Poly
Register a Poly VVX x50 or Edge E series IP phone on your desk phone line.
You need the line's SIP credentials from Settings → Call routing — see Desk phones for how to reveal them.
Connect the phone to your network and power, let it boot to the home screen, then read its IP address under Menu → Settings → Status → Network → TCP/IP Parameters.
In a browser on the same network, open https://<phone-ip> and sign in
as Admin (factory password 456 — change it while you're there).
Go to Simple Setup (or Settings → Lines → Line 1) and fill in:
- SIP Server Address:
sip.telnyx.com, port5061, transport TLS - SIP Outbound Proxy: leave empty
- Phone Display Name: your practice name
- Address, Auth User ID: the line's username
- Auth Password: the line's password
Under the line's Registration settings, set the expiry to 180
seconds if the field is exposed; the default re-registration also works.
Click Save. The line key on the handset turns solid once registered.
Call the number from a mobile — the handset rings. If the line is two-way, dial out to confirm outbound.
Poly's documentation lives at docs.poly.com, and the carrier's guide is Polycom: setup with Telnyx.
