One Way audio
Hello guys,
My topology:
Provider -> SBC -> GW to Qosig
I have a strange behavior with my 3900 SBC ECZ8.1.0 MR-1 Patch 8. For some calls i have one way communication even the end side is sending RTP. With Packet tracer i hear the voice in both direction but after the sbc to the provider there is only one way.
Bad case:
Good case:
For good case we see that the RTP is passing and i can hear ring back tone.
The same call from the same equipments.
Do you have any clue where to look further?
BR
Adrian
