Hello,
when a Phone is connected to a service and sends DTMF tones the tones are not recognized. Seems like the Gateway does not transmit the tones.
MGCP uses follwing DTMF configuration with the BRI interface on basic-net3:
- mgcp dtmf-relay voip codec all mode out-of-band
What can i do?
with kind Regards

Could you please try to turn on:
debug mgcp packet
debug vpm signal
debug vtsp tone
and upload the info.
Thanks

Hello,
here is the trace. Seems like the gateway gets the tones.
Regards
Martin
