One of our customer having CCM 5.1 and IPCC 4.5.For the IPCC calls are getting through a sip server.Recently i changed the script with an option of dialing the Extn number.Upto the sip server the DTMF is working fine and and while its connecting through the IPCC DTMF is not working.I tried all the possible ways,using MTP and changing the DTMF signalling method everythig but still its not working.

Anybody hav idea abt this

Thanks in advance

Arun

Which type of DTMF method you are using for connecting the SIP server and CCM?

If you turn on detailed CCM|SDI and SDL trace do you see the DTMF tone coming into the server?

In traces i can see that DTMF is coming to the callmanager and the strange thing is when i am making calls from the CCM through the sip trunk and sip server the DTMF is working fine.i am enclosing the SDL traces
