However, theres no documentation about setting the forwarding numbers. Is it possible to do that currently?
Since this call was initially asked and answered, we have released an API for managing Call Forwarding and Call Flip rules and phone numbers. We suggest you consult the following documentation:
POST /restapi/v1.0/account/255537016/extension/255537016/forwarding-number HTTP/1.1There are also APIs to modify and delete forwarding numbers (usual PUT and DELETE). You can send a support request to get access to full documentation about forwarding numbers API (and other advanced APIs) for your account.
