What are the top rated call tracking services for 2025?

Hey everyone,

Currently, in the process of evaluating call tracking software for our marketing stack and would love to get your input. We're looking for something that helps us better attribute phone calls to campaigns, understand lead quality, and maybe even unlock insights from conversations.

I was going through G2’s Inbound Call Tracking category, and a few tools consistently show up at the top. Would love to hear if any of you are using these and what your experience has been:

• CallRail: Seems to be the go-to for SMBs and marketing teams- offers keyword-level attribution and integrations with HubSpot, Google Ads, etc.
• WhatConverts: Looks great for capturing all types of conversions (not just calls). Agencies seem to love its reporting.
• Invoca: This one looks more advanced AI-powered conversation intelligence sounds amazing but maybe overkill for smaller teams?
• CallTrackingMetrics: I like that it combines call tracking with business phone features. Anyone using it for both?
• Ringba: Looks built for high-volume call traffic and performance marketers. Curious if anyone's using it outside of affiliate models?

Have you used any of these call tracking tools? What’s made the biggest impact on your conversion visibility? Drop your suggestions below - your insights could help others make smarter attribution decisions.
