# Call Data impact.com offers a call tracking solution that enables brands to easily track a partner's pay-per-call performance. The system makes it simple to track calls and resulting conversions, provides optional call recording, optional IVR (Interactive Voice Response) qualification script, and detailed call analytics. You can easily provision new cost-effective phone numbers for each of your ads. impact.com also offers a web-based javascript technology that can change the telephone numbers on a website to match the ones assigned to a partner so that both calls originating from ads and web landing pages can accurately be attributed back to the partners. The `Call Data` endpoint can be used to log call data from call tracking providers. You can log your call data using the `POST` or `GET` method, and the call data is specified in the request parameter or `POST` form. The list of supported call tracking providers includes, but is not limited to: * Invoca * DialogTech * Retreaver * TalkDesk {% hint style="success" %} **Note:** Reach out to your CSM (or [contact support](https://app.impact.com/support/portal.ihtml?createTicket=true)) to find out how you can configure call tracking for your program. {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
