Fanvil
Register a Fanvil X-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. Press Menu → Status to read its IP address.
In a browser on the same network, open http://<phone-ip> and sign in
(factory login admin / admin — change it while you're there).
Go to Line → SIP and, for SIP Line 1, fill in:
- Line Active: ticked
- Display Name: your practice name
- Username and Authentication User: the line's username
- Authentication Password: the line's password
- Server Address:
sip.telnyx.com, Server Port:5061 - Under Global Settings (or the line's advanced settings), set the
transport protocol to TLS and the registration expiry to
180seconds.
Under Line → Audio (or the line's codec settings), keep PCMU, PCMA and G722 enabled.
Click Apply. The line shows Registered on the status page.
Call the number from a mobile — the handset rings. If the line is two-way, dial out to confirm outbound.
Fanvil's documentation lives at fanvil.com/support, and the carrier's guide is Fanvil X-series: IP phone.
