Hi all,
I have got a major problems with DTMF relay (it's not working).
My setup is a CCME using a SIP Proxy server to reach a remote SIP gateway with some PRI lines on it.
The problem is that on the dial-peers for voip we have configured dtmf-relay sip-notify (even tried rtp-nte as well). This is configured at both the SIP GW with the PRI's connected and on the CCME.
DTMF relay still does not work ?? (tried connecting directly through the gateway with an ATA box converted to SIP and it worked beautifully ??)
Did i miss out on something here ?
My debug shows DTMF negotiation:
01:09:45: sipSPIDoDTMFRelayNegotiation: m-line index 1
01:09:45: sipSPICheckDynPayloadUse: Dynamic payload(101) could not be reserved.
01:09:45: sipSPIDoDTMFRelayNegotiation: Payload type (101) is reserved for requested dtmf relay mode.
01:09:45: sipSPIDoDTMFRelayNegotiation: Case of full named event(NE) match in fmtp list of events.
