PhoneNumber Resource


The Phone Numbers subresource contains the list of Phone Number instances associated with a SIP Trunk.

To purchase a new phone number for your trunk or manage your numbers more generally, you'll need to use the IncomingPhoneNumbers Resource. The SIP Trunking PhoneNumbers Resource is only for adding, removing, and viewing phone numbers associated with a SIP Trunk.
