Hi all,
We have DTMF issue when accessing the third party vm system. We have CS1000 REL 5.0. Does anyone know, how the DTMF tones are sent on the network. Is it inband(DTMF within the RTP) or out-of-band (MGCP signalling). If out-of-band, would it be possible to debug the MGCP signalling to find out if the DTMF signall are sent out on the network?.
Thanks in advance.
