Hello.
Have a SNOM ONE BLUE running pretty good for about 1 month with internal extensions working. Audio is good both ways.
We connected 1 analog line to a SANGOMA port. We cant get NO audio both ways when we dial in to our office # , when we dial out from our office we can be heard yet we dont get audio from that party.
I have been playing around with the RTP in each phone, and when I turn on RTP SYMETRICAL and RTP ENCRYPTION OFF we have audio both ways on just over the extension numbers , no audio from analog lines. If I turn off RTP SYMETRICAL we get no audio on analog lines or extensions.
I have tried every tip on the forum regardin one way audio and cant get audio on analog lines.
