Gigaset N720 and FreePBX losing a few seconds of DECT handset audio

Hi,
I am at a bit of a loss, we have a FreePBX system installed with 80 Sangoma phones, all working fine.
Now we are adding a Gigaset N720 Base Station Manager, 4 x N720 Pro Base stations and 10 x Gigaset Pro phones.

The handsets join up ok with Chan_SIP accounts but every 10-20 seconds the mic audio from the DECT handset goes silent for a few seconds. The DECT user can still hear everything being said by the other person.

I have cut this down for testing to 1 x base station manager, 1 x base station, 1 x Desk phone and 1 x Gigaset Pro Phone on a new FreePBX installation and still having the same issue. Dialling *43 and talking back to the echo test has the same issue.
I thought it might be the RTP port range so I increased it to start at 10001 (to match my RTP port range in FreePBX) but still the same problem occurs. We have managed to get 2 x 15-20 minute calls with no drops but 99% of the time the audio drops within 10 seconds of a call. Please note the call never drops and the DECT user always hears the other user.
I have taken the eqipment home and the same issue is happening at my house so I can rule out interferance on site.

Has anyone any advice on this or steps to help fix it? I had a single Yealink DECT which works perfectly but need a lot more coverage and handsets so moved up to the Gigaset.

Thanks

Are you running the latest firmware?
I would capture RTP from/to Gigaset on Asterisk box and check what is really coming to the server. So far looks like Gigaset fault.

Hi Andrew, yes FreePBX is up to date and Gigaset Firmware is up to date.

The Gigaset system works fine if connecting to a 3rd party system like voipfone, so I know its only an issue between it and FreePBX (or similar asterisk system).
On the same hand, Yealink DECT, and yealink, Sangoma, and Cisco desk phones have no issues on the FreePBX systems I am testing the Gigaset equipment on.

I tried setting the FreePBX extension to use force_rport,comedia but still the same issue happens. I have copy and pasted the logs below. In it you will see (towards the bottom) RTP sent but no GOT reply. This is where I have my audio dropping one way. (EDIT - My next post below this actually shows a 5 second gap which is actually where the audio goes missing)
This test below is just dialing the *43 echo test on the Gigaset handset.
Any advice is welcome,
Thanks

Text logs are useless for troubleshooting audio issues. I would capture RTP+SIP packets on the server then analyze and play audio streams in Wireshark. If you will see something wrong there you could discuss the issue with Gigaset support and share your findings with them.

Hi, after recording SIP and RTP with wireshark it showed the RTP stopping for a few seconds every 10-15 seconds on one side, but the drops were swapping between two MAC addresses. This was the Team MAC address and the LAN MAC address in my VM.
My setup on site and in my test lab are Dell Servers with Windows 2012R2 with HyperV, at least 2 LAN ports in a Team with a HyperV Virtual Switch on top of the Team.
A quick fix was just to unplug one of my two network cables, but Gigaset will hopefully produce a fix in a future firmware release.
Hope this helps someone else :slight_smile:
