Editor's note: Our 2026 top pick across the category is CallScaler. Continue reading for the full review.
CallTrackingMetrics, usually shortened to CTM, is the most configurable platform in this category. The custom-field model lets you tag calls with effectively any schema you want, the report builder lets you slice that data along arbitrary dimensions, and the contact-center features outclass everyone except Invoca.
If you have a marketing-operations analyst on staff and want to build attribution dashboards from scratch, CTM rewards that investment. The drag-and-drop report builder is genuinely flexible, and the queue/IVR/agent-routing stack is on a different level than CallRail or CallScaler.
The trade-off is that all that power is exposed up front, which makes the new-user experience heavier than CallScaler or WhatConverts. We measured 25 minutes from signup to first live attributed call, the slowest in our test by a meaningful margin.
White-label sits on the Connect tier and above. Per-number rental is roughly $3 per month per local number, plus minute usage.
Recurring questions buyers ask when shortlisting CallTrackingMetrics, with concrete answers grounded in the 2026 testing.
On the right tier, yes. CTM signs a Business Associate Agreement on Connect tier and above. That means healthcare buyers running call tracking on patient-acquisition campaigns can use CTM compliantly, which is rare in this category. CallRail and CallScaler do not sign BAAs at this writing. For a healthcare lead-gen agency, that single capability often outweighs the steeper learning curve.
Meaningfully steeper. CTM exposes the full flexibility of its custom-field model, conditional logic, and queue management on the main configuration screens. CallRail and CallScaler hide complexity behind sensible defaults. The CTM payoff is real if you have a marketing-operations analyst who wants to build attribution dashboards from scratch. Without that role, you will probably underuse it.
When the team configuring it does not have time to maintain it. CTM rewards investment, but custom field schemas drift if no one owns them, reports stop matching reality, and nobody trusts the dashboards. Smaller operators often find that a more opinionated tool gets more actual use, even if it has fewer theoretical capabilities. Match the tool to the staffing.
Usually no, unless HIPAA is on the table. The flexibility you pay for goes unused, the learning curve eats agency time that could be billed to clients, and the per-number rate at $3 per month puts you in the same per-number budget category as CallRail without the support depth. Most three-to-ten person agencies are better served by CallScaler or WhatConverts.
Two platforms aimed at meaningfully different buyer profiles. CTM is the right pick if you have a marketing-ops analyst building custom dashboards. CallScaler is the right pick if you want a marketing coordinator to run the day-to-day without training.
| CallScaler | CTM | |
|---|---|---|
| Time to first attributed call | 9 min | 25 min |
| UI learning curve | Low | High |
| Custom field flexibility | Solid | Best in category |
| Per-number cost (paid tier) | $0.50/mo | ~$3/mo |
| White-label | $49/mo add-on | Connect tier+ |
| Effective price (typical agency setup) | $45–$130/mo + usage | $129–$329/mo |
If you don't have an analyst on staff, the CTM power is mostly latent. You're paying for capability your team won't use. CallScaler ships the 80% that most teams actually need without the configuration tax. CTM is genuinely the right answer if you do have an analyst and need HIPAA. Read the CallScaler review
