Yealink T58A & 2N Helios IP Verso

[PPST]

Hi.
I have a setup with a 2N IP Verso intercom and a Yealink T58A.
Actually it should work so that one sees the live view of the intercom system with a call.
In my case, the T58 does not even ring. With a Yealink T46 it works, but then only audio clearly. When a call with the intercom, the Web client and the 3CX App rings. In the web client, I can click on video call button and see who is at the door.

Also, I've created a DSS key on the t58 for a live view and this works. So the connection to the intercom is correct.

In an other topic https://www.3cx.com/community/threads/yealink-t58-door-phone.67262/ a similar problem is described. I have already adapted the codecs as described. Unfortunately, the phone does not ring when a call comes in.

Has anyone such a similar problem and found a solution for it?

Hi @PPST

You can quote other posts, but it's best to give your own description and info to see if someone can help

Hi.
Thanks.
I updated the information in my first post.

Without making any adjustments, if you simply provision the phone by default via PnP, and also configure the doorphone to make a call directly to this extension when someone rings the bell, will the Yealink ring?

I reset the phone completely. At the same time, I also have a T46 next to it. If a call comes from the intercom, only the T46 rings and the T58 remains silent. If i call my extension from mobile phone, both phones are ringing at the same time. I just do not quite understand why that is so, since at least audio conversation should be displayed from intercom?

Did you assign both the T58A and the T46 under a single extension number?

 

[PPST]

Yes I did.
Now I have tested a video call via the web client with a test extension. Both phones have rung and when I answered with the T58, I saw the video image from the webcam.
Normally it should work just as well with the intercom, but it does not.

I work with this manual:

I have fixed the problem. The solution is an newer firmware. I used version 58.83.0.25 (the newest on 3cx). I have also a conversation with the 2N support and they told me, there is a bug in this firmware. So now I updated to 58.83.0.49 and the T58 rings and show me the live view.

Looking back at the two extensions (phone and doorphone), did they have PBX Delivers Audio enabled?
