Phones not ringing on anonymous calls

[JessicaVerschelling]

Hi,
We have a problem with incoming anonymous calls.
When an incoming call is anonymous the phones are not ringing. In activity log we see 'has failed; Cause: 480 Temporarily not available/INVITE from xxx'
When we use the same extension in the 3CX android app the extension is ringing.
We're using Fanvil X4 phones and a Yealink W52P. Firmware of both phones is up to date.
Some of the Fanvils are working, but can't see any difference in phone config.

3CX and phones are up to date. Trunk is a supported trunk.

Someone any idea where to watch?

Hi,

For the Yealink please check in Web User Interface:
Account > Basic > Local Anonymous Rejection is "Off"
If it is set to 1 (On), the IP DECT phone will automatically reject incoming calls from users enabled anonymous call feature. The anonymous user’s phone LCD screen presents “Forbidden".

As for Fanvil I can't help you.

Do you have inbound rules filtering something on anonymous calls?
Nothing set on provider side to filter anonymous calls ?

Thanks for the answers. We've found the solution for the Fanvil. Very stupid, anonymous on the blacklist on the Fanvil itselfs..

We don't have set any filters on inbound rules or on provider side.

For the Yealink we didn't found the solution yet. The local anonymous rejection is 'off' .
For this calls we get:
Call to XX has failed; Cause: 487 Request Cancelled/INVITE from XX

Maybe the easist way for the Yealink is to reset the base to factory default and re-provisioning it again.
