Gigaset inter-handset issues

I have a strange issue where my Gigaset handsets (each with a different extension assigned) are able to be called from any other extension, but when another handset calls via FreePBX the call is created, but no audio can be heard.

What is really strange, is that from a technical point of view it is perfectly possible for the handsets to talk to each other via FreePBX, I was able to determine this because calling another handset via a RingGroup works

I have looked at the differences in the log file when the call is successful and unsuccessful and I think the most useful pieces of the log file can be seen below. The big difference here seems to be that the call is only successful when I see Strict RTP learning complete in the log file. Any ideas why it’s not working when I call directly?

FreePBX: 14.0.3.2 (10.200.5.32)
EXT: 201,202,203 are all registered on a GigaSet N300IP (10.200.5.60). Each extension is mapped to a different handset.
EXT: 204 is a Grandstream GCP 1610 (10.200.5.61)

This looks like an extension problem in FreePBX more than a problem with the handset.

Do you have (or have you ever had) any modules installed like CoS or Extension Routing?

Since you are trying to call the handset you are using (they are all on x.x.x.60), there might be something in the setup that isn’t allowing you to connect. It is weird that you can get there through a ring-group, but calling the handset you are on from the handset you are on does seem like an edge case.

Try turning off RTP Symmetric for the Gigaset extensions. If that causes no audio at all, try turning off STUN or other NAT traversal logic in the Gigaset.

If you still have trouble, post a log including SIP trace of the failing case. (At the Asterisk command prompt, type
pjsip set logger on
and then try the failing call.

Thanks so much for looking in to this guys…

Sorry, to be clear…
The Gigaset N300IP (10.200.5.60) has three VoIP enables DECT handsets attached to it. Within the N300IP admin screen I can assign a different FreePBX extension to each handset, so what I am trying to do here is call Handset 2 (ext 202) from Handset 3 (ext 203). I am not calling the same handset that I am using.

This made no change to the situation…

  • Gigaset handset-to-handset call, but no audio
  • Granstream desk phone to Gigaset handset call works perfectly

pjsip set logger on

Here are the pjsip logs for the two calls, I am really not sure what I am looking at here, so any help from @Stewart1 or of course anyone else would be hugely appreciated.
