I have 2 bases. A C47H and a 550A IP BASE (both from Gigaset).
The first one works fine.
With the second I have no sound on both sides.
I use asterisk-22.4.0.
I must say that with 2 softphones linked to the asterisk server work well, even with NAT.
It’s only the hardphone connected to the 550A IIP BASE that has this issue.
In its conf there is only one rtp port that can be configured. Its value is 10000.
In asterisk rtp.conf I have the 10000-20000 interval defined.
The problem is only in the sound part.
It would be nice if someone could help me searching.
I have spent 3 days looking for the cause, I have viewed numerous tutos.
I’m here today because I’m lost.
Thanks @david551
That’s exactly what I don’t understand.
Hardphone is configured for using rtp port 10000.
I must add that it’s not possible to configure a range.
Can it be a hardware failure ?
The phone (and its base) is new.
If it was only a matter of caller port it would could work in the way caller - callee. It’s not the case.
