> The **Profile Guesser integration** connects an external caller-lookup service, so an incoming caller's name and company appear on the phone of whoever answers. Unlike most integration types it can be configured more than once, for tenants using several lookup services.

## Overview

Profile Guesser is an integration type that links your PBX to a third-party caller-lookup service. When a call comes in, the PBX asks that service who the number belongs to and shows the result to the person answering.

## What it does

On an incoming call, the PBX queries the configured Profile Guesser endpoint and surfaces the returned caller name and company on the answering phone. The endpoint is a POST that accepts a JSON payload containing a `phone_numbers` array, and each request carries an access token for authentication. Both the endpoint URL and the access token are set on the integration:

- **Profile Guesser URL** - the POST endpoint that accepts the `phone_numbers` array.
- **Profile guesser access token** - the token sent with each request to authenticate against that endpoint.

This type can be configured more than once if you need to connect to more than one lookup service.
