# A technician is unable to make outbound calls through ServiceTitan mobile

## Problem

The technician is trying to call customers through the app on his mobile device. The calls do not go through.

## Solution

### Call the technician's number

Call the technician's number directly. The system calls the number in the technician's profile first. If there are any issues with this, an outbound call fails.

- If you are unable to get through to the technician number, the issue is not related to ServiceTitan. Contact the technician's phone provider and continue troubleshooting.
- If you are able to get through to the technician's phone directly, continue on Step 2.

### Resolve any device-related issues

- Add your office *Outbound Caller ID* as a contact in the technician's device.
- Ensure no apps are installed that block spam calls (IOS).
- Ensure *Focus* mode is turned off (Android).
- Make sure *Do not disturb* is turned off.
- Uninstall the mobile app and reinstall if it is on the same device receiving calls.

### Call the customer's number

Find the customer's number in their ServiceTitan Customer Record.

- If you are unable to connect, there is an issue with the customer's phone number.
- If you are able to connect, continue troubleshooting.

Replace the number on the customer profile with another one and place an outbound call to check if the call goes through.
