Phone numbers API: Five9, RingCX, and required SIP domain
You can now import Five9 and RingCX numbers through the POST /custom-numbers endpoint.
For all other providers on that endpoint, termination_uri (SIP domain) is now required. Five9, RingCX, and Zoom are not affected; Synthflow still sets their SIP domain automatically.
