# Migrate a COEX number to 360Dialog

Businesses that are using a Coex number with an alternate BSP can migrate the number to 360dialog. But the process requires disconnecting the number from both the API and Business App and then using the Embedded Signup to re-register the number. 

## **How to migrate a phone number**

### Disconnect the number from the Cloud API
