Cordless (DECT)
Register a Yealink W-series DECT base station so cordless handsets ring on your desk phone line.
A DECT base station registers with the line once; cordless handsets then pair with the base — useful for surgeries where the phone moves around. You need the line's SIP credentials from Settings → Call routing — see Desk phones for how to reveal them.
Connect the base station (for example a Yealink W70B or W73P bundle) to your network and power. Pair a handset with the base (OK → Settings → Registration, then press the base's pairing button).
On the paired handset, press OK → Status to read the base's IP address.
In a browser on the same network, open https://<base-ip> and sign in
(factory login admin / admin — change it while you're there).
Go to Account → Register, pick Account 1, and fill in:
- Line Active: Enabled
- Label and Display Name: your practice name
- Register Name and User Name: the line's username
- Password: the line's password
- Server Host:
sip.telnyx.com, port5061, transport TLS - Server Expires:
180
Under Account → Number Assignment, assign the account to every handset that should ring.
Click Confirm, then call the number from a mobile — the cordless handsets ring. If the line is two-way, dial out to confirm outbound.
One base station supports multiple handsets, and they all ring together — you rarely need a second registration.
