You can forward incoming calls on any number of your choice via our Flow Builder or through the API.
When you have purchased a Voice-enabled virtual mobile number, you can easily forward all incoming calls to another phone number or SIP URI by using our Flow Builder.
Check How to forward calls to another phone number or SIP URI for a step by step guide on how to set this specific flow.
