Solved T46S - No Service

[Rob Whitney]

Walked in this morning and all Yealink T46S phones show ‘No Service’ at the top, have little red ‘x’s on all the icons (users and shared parking). I get a dial tone (but can't make or receive calls), can’t park, transfer or buzz other users.Any thoughts?

That means they are unregistered.

start by checking blacklisted IP just in case, then check the phones configuration in 3CX to be sure everything is fine (SBC address, ports, etc.).

Restart the phones and see. That can happen when the Internet connection is unstable or if the phones can't reach the PBX.

Before we can help, need more info on your setup https://www.3cx.com/community/threads/information-to-provide-when-requesting-help.67558/

Does the phone have a valid IP ?
Have you check 3CX activity logs ?

Hi Rob,

Please go ahead as the other members have suggested. Also check that your PBX is actually working (via management console or log into your webclient)

Was just our main computer that has 3CX tunnel software. It crashed overnight doing an automatic Windows update. All set now.

Glad to hear it was resolved
