The picks
- CallRail — Best for marketing teams tracking multi-channel lead attribution

- Invoca — Best for enterprise lead gen at scale
- Google Ads Call Tracking — Free if you’re already running Google Ads
- OpenPhone — Cheapest option with zero technical setup
#1 Pick
CallRail is the obvious choice for most marketing teams focused on lead gen. It does one thing well: tell you which campaigns are driving phone call leads. The interface is clean, attribution models are straightforward, and you won’t need a week of training to get value from it.
Why I picked this
CallRail handles the core lead gen use case—multi-channel attribution—better than anyone else at this price point. You get dynamic number insertion for your website, keyword-level tracking for paid search, and call recordings that sync to your CRM. The reporting actually makes sense without requiring a data analyst to interpret it.
The integration with Google Ads and Analytics is solid. You can push call conversions directly into your ad accounts, which means your bidding algorithms get the full picture of what’s converting to leads.
The tradeoff: CallRail is purpose-built for marketing attribution. If you need a full phone system with IVR trees, call queuing, and outbound dialing, you’re looking at the wrong category of software.
Skip this if…
- You need a complete phone system, not just lead tracking
- You’re an agency managing 50+ client accounts (pricing gets steep)
- Your call volume is under 50 calls/month (probably not worth the cost)
#2 Pick
CallTrackingMetrics (CTM) shines when you need call tracking to plug into a larger lead gen ecosystem. Their API is more flexible than CallRail’s, and they have deeper integrations with marketing automation platforms, CRMs, and custom webhooks.
Why I picked this
CTM is built for marketing teams that live in Salesforce, HubSpot, or Marketo and need inbound call leads to trigger specific workflows. The conversation intelligence features are more advanced—you can route calls based on what the caller says, trigger automations from call outcomes, and build custom lead scoring models.
If you’re an agency managing lead gen for multiple clients, CTM’s account structure is better designed without the pricing penalties you’d hit with CallRail.
The honest answer: CTM has more features than CallRail, but it also has more complexity. If you don’t need the integrations, you’re paying for capability you won’t use.
Skip this if…
- You want simple attribution without workflow automation
- Your team doesn’t have bandwidth to configure integrations
- You’re not already invested in a marketing automation platform
#3 Pick
Invoca is the heavyweight option for enterprise lead gen. If you’re processing thousands of inbound lead calls per month and need AI to analyze them at scale, this is where you end up. It’s not cheap, and it’s not simple, but for the right use case it’s worth it.
Why I picked this
Invoca’s conversation intelligence is genuinely more sophisticated than the mid-market options. The AI can identify caller intent, detect lead quality signals, and feed that data back into your ad platforms with more granularity. For organizations where a single high-value lead might be worth $10K+, that precision matters.
The platform also handles complex routing scenarios—multiple locations, franchise networks, dealer networks—better than the alternatives.
The catch: Invoca requires real implementation effort and dedicated resources to get value from. This isn’t a tool you sign up for and start using in an afternoon.
Skip this if…
- You’re a small/mid-sized marketing team (you’ll overpay for features you don’t need)
- You don’t have dedicated marketing ops resources
- Your average lead value doesn’t justify the investment
- You need to be live in a week, not a month
Honorable mentions
#4
If most of your lead gen runs through Google Ads, the built-in call tracking might be enough to start. You can track calls from call extensions, call-only ads, and website calls using a Google forwarding number. It’s free, already integrated with your ad account, and feeds directly into your conversion data.
You won’t see this option in most “best call tracking software” articles because it’s free—no affiliate commission for the writer. We’re not affiliate, so we’ll tell you: try this first before paying for anything.
Choose this if: Google Ads is your primary lead gen channel and you want basic call attribution without paying for another tool.
Skip it if: You need to track calls from organic search, social, or other channels—Google’s tracking only covers Google Ads traffic.
#5
OpenPhone is the simplest way to start tracking lead calls if you’re not technical and don’t want to mess with integrations. You get a business number, basic call analytics, and a clean mobile/desktop app. No dynamic number insertion or keyword tracking—just straightforward call logs you can review to see what’s working.
Choose this if: You’re a small team, want the cheapest paid option, and just need to start tracking calls without a learning curve.
Skip it if: You need real marketing attribution—OpenPhone won’t tell you which campaigns drove which calls.
How to choose
Choose CallRail if you’re a marketing team that needs clear lead attribution and wants to be up and running fast. It’s the right answer for 80% of lead gen teams asking this question.
Choose CallTrackingMetrics if you have complex integrations, manage lead gen for multiple clients, or need calls to trigger specific workflows in your CRM or marketing automation.
Choose Invoca if you’re enterprise-scale, process high volumes of inbound leads, and have the resources to implement and manage a sophisticated platform.
Choose Google Ads Call Tracking if your lead gen is mostly Google Ads and you want to start tracking calls for free before investing in a dedicated tool.
Choose OpenPhone if you’re a small team that just needs a trackable business number without any technical setup or learning curve.
The honest take: most marketing teams doing lead gen should start with CallRail. If budget is tight, start with Google Ads’ free tracking and upgrade when you need multi-channel attribution.
