Call Me Impressed: 8 Inbound Call Tracking Software I Evaluated

I watched it happen in real-time. A sales rep picked up the phone, ready to close, but the caller sounded impatient. “I already spoke to someone,” they said. My colleague at one of my earlier jobs scrambled: there was no conversation record, and they had no idea which campaign brought them in. That call, which could have closed a high-value deal, became another missed opportunity.

That moment made me realize the importance of using the best inbound call tracking software. We were tracking website visits, email opens, and ad clicks. Yet, every time the phone rang, we had zero visibility into where those leads were coming from or how to follow up effectively.

Recently, I evaluated the best inbound call tracking software solutions to help you avoid situations like this. I dug into hundreds of G2 reviews about call attribution, analytics, automation, and integrations, which are everything a business needs to turn every call into an opportunity. Here’s what I found. 

My experience researching the best inbound call tracking software

I see inbound call tracking software as a tool that helps businesses monitor, analyze, and optimize their phone call interactions. It assigns unique phone numbers to marketing channels like ads, landing pages, or social media so users can see which campaigns drive the most calls. When a customer dials one of these numbers, the software captures details like the caller’s number, location, call duration, and even conversation transcripts. This allows users to understand customer behavior, attribute calls to the right sources, and refine marketing strategies for better ROI.

The best inbound call tracking software should do more than just log calls. It must offer dynamic number insertion (DNI) to track calls based on visitor sessions and provide real-time analytics to identify high-quality leads. Seamless integration with CRMs, Google Analytics, and ad platforms is essential for accurate marketing attribution. I also look for AI-powered call recording and transcription to help sales teams understand conversation trends.

How I evaluated the best inbound call tracking software

Here’s what I considered while exploring the best inbound call tracking software solutions. 

• Dynamic number insertion: Users need inbound call tracking software that supports dynamic number insertion to track calls based on user sessions. This ensures they can see which specific marketing source, Google Ads, social media, or organic search, led to a call. Without DNI, you're stuck with static tracking numbers, which don’t provide the granular insights needed to optimize campaigns effectively.
• Call attribution and source tracking: Accurate call attribution is non-negotiable. A good software should tell exactly which campaign, ad, keyword, or webpage drove each inbound call. Ideally, it should support multi-touch attribution, so users can see the full customer journey instead of just the last touchpoint before a call. The better the attribution, the more effectively teams can allocate their marketing budget.
• CRM and marketing platform integration: Inbound call tracking isn’t useful if it operates in isolation. I focus on tools that integrate seamlessly with CRM, Google Analytics, Google Ads, Facebook Ads, and other marketing automation tools. This ensures sales and marketing teams have real-time access to call data, making it easier to follow up on leads and measure ROI accurately.
• AI-powered call recording and transcription: A good inbound call tracking tool should analyze conversations. AI-driven call recording and transcription allow users to review customer interactions, extract key insights, and even identify patterns in sales calls. If the software includes keyword spotting and sentiment analysis, that’s a huge plus for improving sales strategy.
• Call routing and IVR capabilities: If your business handles a high volume of inbound calls, you need smart call routing and an interactive voice response (IVR) system. These ensure that calls go to the right department or sales rep based on predefined rules, improving response time and customer experience. Some advanced platforms even use AI to route calls based on intent analysis.
• Ease of use and customer support: Even the most feature-rich software is useless if it’s too complicated. I look for an intuitive dashboard, simple setup, and easy-to-understand reporting tools. It's also important to have responsive customer support with live chat, phone, and email options, ideally 24/7, especially if the business operates across multiple time zones.

To be included in the inbound call tracking software category, a product must:

• Create unique tracking phone numbers for various marketing campaigns
• Link incoming calls and messages to specific ads, campaigns, or keywords
• Capture and track all inbound calls associated with each tracking number.
• Deliver real-time analytics and detailed call reports
• Sync with marketing and sales platforms to analyze lead data and conversion metrics

*This data was pulled from G2 in 2025. Some reviews may have been edited for clarity.  

1. CallRail

Users appreciate how CallRail helps identify which marketing efforts drive the most calls. Instead of blindly guessing which campaigns are working, they can see concrete data on which ads, keywords, or sources generate phone leads. This feature gives users confidence in marketing spend and helps refine future strategies. They don't have to rely on assumptions or incomplete customer feedback.

One thing I’ve seen G2 reviewers highlight is how helpful CallRail’s AI-powered conversation summaries are. Instead of listening to full recordings or scanning entire transcripts, users can quickly get a summary of each call. It’s a huge time-saver—especially for teams managing a high volume of calls each day.

Call routing also gets strong feedback. Reviewers mention that CallRail automatically directs calls to the right person or team, helping potential customers avoid unnecessary transfers or wait times. This improves the caller experience and reduces the risk of missed leads due to unanswered or misdirected calls.

Access to call recordings is another feature that stands out. Many users say it’s valuable for training and quality monitoring. If you’re managing a sales or support team, being able to reference actual conversations makes coaching far more effective than relying on general feedback alone

One of the biggest challenges in marketing is proving ROI, and I’ve seen G2 reviewers mention that CallRail makes this easier. Users appreciate being able to track which campaigns, keywords, or ads drive phone calls, especially for businesses where conversions happen over the phone rather than through online forms. Instead of guessing whether ad spend is paying off, users can clearly see which sources are generating leads.

That said, getting everything set up can be a bit of a hurdle. I noticed feedback from users who found the configuration process a bit time-consuming. For someone who isn’t particularly tech-savvy, this part of onboarding could be frustrating.

Another concern is data reliability. A few reviewers mentioned occasional issues with calls not being logged or recorded properly. When you're relying on call data to evaluate campaign performance, even a small percentage of untracked calls can skew results and lead to inaccurate conclusions.

Notifications are another area where CallRail could improve. While users like getting alerts for important calls, some feel the system isn’t flexible or urgent enough. More customizable notification options would go a long way.

I also noticed reviewers wishing for more automation after a call wraps up. Features like sending a follow-up text or email automatically could add value, but it seems CallRail doesn’t offer much built-in functionality in this area yet. That kind of follow-up would help close the loop and make the tool even more useful for lead management.

What I dislike about CallRail:

• I’ve seen G2 users mention that setting up CallRail can be a bit of a hassle. Configuring tracking numbers and routing takes time, and it’s easy to see how someone who’s not very tech-savvy might struggle with the process. The insights are definitely valuable, but getting everything set up right requires some patience.
• Missing call data is another concern. A few reviewers pointed out that if even a small percentage of calls aren’t tracked properly, it can throw off the accuracy of marketing reports. When you’re relying on that data to make decisions, any gaps make it harder to trust the full picture.

What G2 users dislike about CallRail:

2. Invoca

Users appreciate how Invoca delivers real-time data that allows businesses to act immediately on customer insights. This is critical for industries where quick decision-making can improve conversion rates or customer satisfaction. Having immediate access to call data means that marketing and sales teams can adjust strategies without delays.

Training is often a hurdle with new software, but I’ve seen G2 reviewers consistently highlight Invoca’s onboarding process as a strength. Many users say they were able to navigate the platform effectively after a short training session, which suggests Invoca puts real effort into user education. A well-structured training experience minimizes downtime and helps teams ramp up quickly.

Another standout is the depth of caller insights. I noticed reviewers praising how Invoca goes beyond basic metrics like call duration or phone number, it captures customer intent and behavior. This kind of detail allows for more personalized follow-ups and stronger customer interactions. The more granular the data, the more useful it becomes for refining both marketing and sales strategies

Some tools start great but become unreliable over time, yet Invoca appears to be a consistent performer. I like that users who have used it for an extended period report continued satisfaction, which speaks to the platform’s reliability.

One challenge that stands out in reviews is the lack of built-in support for certain data parameters. This can make it more cumbersome to track specific interactions, forcing users to rely on workarounds. This lack of flexibility in handling custom data slows down workflows and creates additional complications.

What I dislike about Invoca:

• I’ve seen G2 reviewers say that while Invoca is generally strong, downloading large reports can be slow. Users also mention a few areas where there’s room for improvement, like better match rate accuracy with CRM data, more intuitive reporting and filtering, easier Salesforce integration, and a smoother process for expanding licenses.
• Another common pain point is the lack of built-in support for certain data parameters. I’ve noticed feedback from users who had to rely on workarounds to track specific interactions, which adds unnecessary complexity to the process.

What G2 users dislike about Invoca:

“The reporting tools can be a bit clunky. We have not found a way to have collaborative custom reports in-platform, as each can only be viewed by the individual owner and shared (not editable). Also, you must wait for an email link to download reports/data rather than going to your computer's files. Deeper integration with Microsoft Search Ads would be nice as well.”

3. Ozonetel CloudAgent

G2 reviewers appreciate Ozonetel CloudAgent’s depth of call reports. Having access to detailed call analytics helps understand customer behavior and agent performance. The ability to track specific call trends, such as peak call times or frequently asked queries, allows businesses to optimize their customer service strategy.

I’ve seen G2 reviewers point out how Ozonetel CloudAgent excels at distributing incoming calls efficiently. The system helps reduce wait times by routing calls to the right agents based on predefined criteria like department or skill set. For businesses handling high call volumes, this kind of smart routing minimizes congestion and improves the overall caller experience.

Another feature that gets strong feedback is call monitoring. Users appreciate that supervisors can listen to live calls and provide real-time coaching. It’s a valuable tool for training and quality assurance, allowing intervention while the conversation is still happening, rather than waiting for post-call reviews.

Reliability also stands out in reviews. I’ve noticed users mention that the platform experiences minimal downtime, which is crucial for businesses that rely heavily on inbound calls. Knowing the system remains stable and consistently available gives teams confidence that they won’t lose revenue or miss critical customer interactions.

One issue I’ve seen mentioned in G2 reviews is call overlapping during peak times. When there’s a surge in inbound calls, multiple agents may try to pick up the same call, which creates confusion and slows down response times. For businesses that regularly experience high call volumes, this can lead to longer resolution times and frustration for both agents and customers.

While the reporting feature is generally strong, I’ve noticed feedback about occasional inconsistencies in certain reports. When data isn’t accurate or complete, it can lead to misinformed decisions—especially for teams relying on analytics to monitor performance and spot trends. For a call tracking platform, consistent and reliable reporting is essential, so any discrepancies can undermine confidence in the system.

What I dislike about Ozonetel CloudAgent:

• I’ve seen G2 users mention that during peak hours, multiple agents sometimes try to pick up the same call, which leads to confusion and delays. 
• Accurate reporting is also critical for decision-making, so it’s concerning when data inconsistencies show up. 

What G2 users dislike about Ozonetel CloudAgent:

“There are issues with the software. When an agent is on call, the dashboard still shows idle status. There is a restriction on downloading the data; at a time, only two months' data can be downloaded.”

- Ozonetel CloudAgent Review, Ritu L.

4. WhatConverts

Users like how well WhatConverts attributes leads. It tracks calls and provides detailed insights into where those leads originated. This clarity makes it much easier to understand which marketing channels perform best. Optimizing campaigns can feel like a guessing game without this kind of insight. Knowing which ads, keywords, or sources drive quality leads is a huge advantage.

I’ve seen G2 reviewers consistently highlight how WhatConverts stands out with its clear and straightforward reporting. Unlike other tracking tools that can feel overly complex, users say this platform makes it easy to interpret data and act on it quickly. As a marketer, I really value being able to identify high-quality leads without spending extra time deciphering reports.

Lead tracking accuracy is another strength. I’ve come across reviews mentioning that WhatConverts reliably captures calls and attributes leads correctly. For businesses that depend on phone inquiries, having consistent, trustworthy data is critical, and it’s something this tool seems to deliver well

I’ve seen G2 users mention that while WhatConverts is generally cost-effective, the pricing structure can be a bit unclear. It’s not always obvious how costs scale with usage, which can be frustrating for businesses that need predictable expenses month over month.

Another point that comes up is its limited functionality as a CRM. WhatConverts excels at tracking leads, but it doesn’t offer full client management features. For teams already using an established CRM, this isn’t a big issue—but for those looking for an all-in-one solution, the lack of built-in CRM capabilities might be a drawback.

I’ve also noticed feedback suggesting that WhatConverts is primarily geared toward U.S.-based businesses. For international users, things like phone number formatting, support hours, or region-specific features may not be as well-aligned, which could create some friction for global teams.

What I dislike about WhatConverts:

• While G2 reviewers often describe WhatConverts as cost-effective, some note that the pricing structure can be tricky to navigate. It’s not always clear how costs scale with usage, which can make budgeting and forecasting more difficult.
• WhatConverts is praised for its lead tracking capabilities, but users point out that it doesn’t function as a full CRM. For those who need deeper client management features, integrating an additional tool is often necessary. This can be a drawback for businesses looking for an all-in-one solution.

What G2 users dislike about WhatConverts:

“At this stage, we don't have much to discuss regarding dislikes. Initially, we found their pricing confusing, but it makes much more sense once we dive in.”

- WhatConverts Review, Donovan R.

5. CallTrackingMetrics

Users like CallTrackingMetrics’ ability to attribute calls effectively. It can pinpoint whether a call came from paid ads, organic search, or other sources, providing detailed insights into campaign performance. This level of attribution helps marketers like me fine-tune their marketing strategies without relying on guesswork.

G2 reviewers often highlight how CallTrackingMetrics goes beyond basic call counts by offering detailed call analytics. The platform gives users a clear view of customer interactions, including caller behavior, call duration, and trend patterns. This level of granularity is especially helpful for adjusting customer experience strategies in real time based on actual call data.

Location-based insights are another standout. I’ve seen feedback from users who found it valuable to understand where calls are coming from, particularly for businesses operating across multiple regions. These insights help teams identify which areas generate the most engagement, making it easier to optimize local marketing efforts or guide expansion strategies.

Another benefit reviewers mention is that even businesses using a single phone line can still take advantage of CallTrackingMetrics’ tracking capabilities. Users like that they don’t need to manage multiple tracking numbers to get meaningful insights, simplifying the process without sacrificing visibility into performance.

I’ve seen G2 reviewers mention that while CallTrackingMetrics is feature-rich, the onboarding and setup process can take longer than expected. Some users reported delays stretching months beyond initial timelines, which can be frustrating for businesses that need a call tracking solution up and running quickly.

Spam filtering is another area where users see room for improvement. I’ve noticed feedback about the platform not effectively blocking unwanted calls. For businesses that receive a high volume of spam, this can skew reporting and require manual cleanup—adding unnecessary work and affecting data accuracy.

Customization also has its limitations. While CallTrackingMetrics offers strong tracking features, several users pointed out that deeper customization can be difficult without API access. For teams with specific workflow requirements, the lack of more flexible, built-in customization options can lead to workarounds or additional development effort

What I dislike about CallTrackingMetrics:

• I’ve seen G2 reviewers mention that setting up CallTrackingMetrics can take longer than expected. For businesses eager to start tracking and optimizing their marketing efforts, these delays can be frustrating and slow down momentum.
• Spam calls are another common issue. Users note that unwanted calls can still show up in reports, cluttering the data and affecting accuracy. For businesses that receive a high volume of spam, this can become a recurring hassle.

What G2 users dislike about CallTrackingMetrics:

“The learning curve can be challenging for users unfamiliar with call tracking analytics. Small businesses with limited budgets may also find the pricing too expensive.”

- CallTrackingMetrics Review, Supriya R.

6. Vonage Contact Center (formerly NewVoiceMedia)

G2 reviewers like Vonage Contact Center’s competitive international calling rates. While inbound call tracking is often tied to domestic operations, having a reliable and cost-effective way to handle international calls is a game-changer. It ensures users don’t have to worry about excessive charges when dealing with customers from other countries. 

G2 reviewers often highlight how Vonage Contact Center uses AI-driven analytics to improve inbound call handling. Users appreciate features like AI-assisted call routing, sentiment analysis, and even automated responses. These capabilities help reduce the workload on human agents while providing deeper insights into customer interactions. Instead of just logging calls, the platform enables data-driven decisions by identifying trends and pinpointing areas for improvement.

Scalability is another area where Vonage gets strong feedback. I’ve seen reviews noting that the platform can handle high call volumes without lag or dropped calls, which is essential for businesses that rely heavily on inbound communication. That kind of reliability helps ensure customer satisfaction and prevents missed opportunities.

Call flow customization is also a key strength. According to users, the ability to tailor routing paths and direct callers to the right agents or departments makes the platform especially valuable for teams managing complex service requests or multi-step support workflows.

Some users have mentioned experiencing issues with messaging functions, which can be a drawback for businesses that rely on omnichannel communication. If inbound call tracking software is expected to integrate seamlessly with SMS or other messaging platforms, reliability in this area is necessary. Users dislike that inconsistent messaging features could lead to missed messages or delayed responses, negatively impacting customer experience. 

I’ve seen G2 users point out that while Vonage Contact Center offers powerful AI-driven features, there can be a learning curve, especially when diving into the more advanced tools. These capabilities may not feel intuitive right away and often require training or extra resources to use effectively.

Customer support is another area where reviewers see room for improvement. Some users mention delays in getting help when issues arise, which can be especially frustrating for businesses that depend on uninterrupted customer communication. Timely assistance is critical when managing high volumes of inbound calls, so gaps in support response can become a real pain point.

What I dislike about Vonage Contact Center:

• A few users have reported issues with Vonage’s messaging functions, which makes omnichannel communication less reliable. Delayed or missed messages can create unnecessary frustration for businesses and customers.
• Some businesses might find the learning curve for Vonage Contact Center’s advanced features challenging. While AI-driven tools are powerful, they require time and training to use effectively.

What G2 users dislike about Vonage Contact Center:

“The wait time for a customer is a bit too long, especially when the customer care is meant to be there for the customer immediately when required.”

- Vonage Contact Center (formerly NewVoiceMedia) Review, Arshdev S.

7. Ringover

Ringover’s call quality is frequently praised by users. A strong and stable connection makes a significant difference when handling customer inquiries. Clear conversations reduce misunderstandings, ensuring you can provide accurate information without asking customers to repeat themselves. Many providers struggle with maintaining consistent audio clarity, but knowing that Ringover prioritizes this aspect gives users confidence in its reliability. 

I’ve seen G2 users appreciate that Ringover offers call transcriptions, making it easier to track conversations without the need for manual note-taking. Even if the transcription isn’t flawless, reviewers say it provides a solid reference point for reviewing past calls and analyzing customer interactions.

Quick implementation is another standout feature. Many reviewers note that Ringover can be set up and running faster than other call tracking platforms. For businesses trying to avoid long onboarding processes or technical delays, this speed is a major advantage. It’s a relief when a tool delivers on the promise of easy setup without requiring extensive support.

One issue I’ve seen in G2 reviews is the accuracy of Ringover’s call transcriptions. While having a written record is helpful in theory, it can become a hassle if the transcript includes frequent errors. Misinterpretations could easily lead to confusion, and for industries that rely on precise documentation, this lack of accuracy means extra time spent double-checking details manually.

Call connection issues, though not constant, are another concern. Some users mention that occasional dropped calls or audio delays can disrupt conversations and impact customer experience. Even if the overall call quality is good, these intermittent issues can cause unnecessary follow-up or frustration for both teams and customers.

I’ve also noticed feedback about the complexity of managing inbound call tracking settings. Configuring routing rules or adjusting tracking parameters sometimes takes more steps than expected. While users appreciate the platform’s advanced features, they often say those tools should be easier to access and modify, especially for non-technical users who need to make quick changes on the fly.

What I dislike about Ringover:

• While call transcriptions are a helpful feature, I’ve seen G2 users point out that frequent errors can make them unreliable. 
• Even though call quality is generally strong, occasional connection issues still come up in reviews. Users mention that dropped calls or audio delays, while not constant, can disrupt communication. 

What G2 users dislike about Ringover:

“Sometimes the transcript makes a few errors, but nothing major.”

- Ringover Review, Josh F.

8. 800.com

Users love how 800.com's toll-free number gives them a more established and credible image. You can also get a custom number that aligns with your brand, making it easier for clients to remember. It’s a simple yet effective way to improve customers' perception of your business.

I’ve seen G2 users highlight the reliability of 800.com’s call forwarding as one of its key strengths. The consistent forwarding ratio and reduced number of dropped calls give teams peace of mind, especially when handling high-value leads or urgent customer inquiries. Knowing that business calls will reach you regardless of your location is a major advantage.

The platform also gets praise for its flexibility when setting up toll-free numbers. Reviewers mention that you're not locked into a one-size-fits-all setup. Whether it’s configuring a vanity number or customizing routing options, users say they can tailor the service to fit their specific needs. That level of control helps businesses fine-tune how they handle calls and improve overall customer engagement.. 

One downside I’ve noticed in reviews is that 800.com can be more expensive than other pay-as-you-go services. While the features are useful, the pricing might not be ideal for businesses needing occasional call tracking. Some competitors offer more budget-friendly options, making you consider whether you are getting the best value for your needs. 

G2 reviewers also mention that while the verification rules for setting up a toll-free number are understandable, the process can feel restrictive. There are specific compliance requirements to meet, and making changes isn’t always straightforward. If the steps aren’t followed exactly, users report delays in getting numbers properly set up. It would be helpful if the verification process were more streamlined, with less back-and-forth to get everything approved. 

What I dislike about 800.com:

• One drawback I’ve noticed is that 800.com can be more expensive than some other pay-as-you-go options.
• I’ve seen G2 reviewers mention that while the verification rules for setting up a toll-free number make sense, the process can still be frustrating. There are compliance requirements that need to be followed closely, and if any changes are needed, it can quickly become a hassle.

What G2 users dislike about 800.com:

“While the service is good, it is slightly more expensive than some competitors, which might be a consideration for small businesses on a tight budget.”

- 800.com Review, Boris V.
