We have a N720 DM with 3 Base stations installed at one of our customers and until SP6
we didn't have any issues with audio. Everything was working fine till then. This weekend
the update to SP6 was done and since monday issues with audio on the Handsets.
We haven't changed a single thing in the configuration. The handsets have PBX delivers audio on.
No Stun, no SBC or any of the know limitations specified on https://www.3cx.com/sip-phones/gigaset-n720/
We can't seem to pinpoint the problem. A Server reboot resolves the problem temporary,
but we'll have the customer back on the line in a couple of hours. Anyone can help or point us in the right direction. Here is the verbose log of one of the calls made:
