I  tried to change setting in sip trunk (dtmf signaling method) and  it is not working

Please advise.

what is the call flow?

CUCM---sip---CUBE---sip---Provider?

what is the DTMF method set on the CUCM SIP Trunk configuration?

if it is CUBE, what is the dtmf method configured on the inbound & outbound dial-peers?

[eran moyal]

CUCM---sip---Box ---Provider

Dtmd signaling Method:OOB and RFC 2833

[Suresh Subramanian]

I assume the Box you mean here is Cisco Gateway (CUBE).

can you post the running config? what is the dtmf method your provider expects to receive?

can you collect "debug ccsip message" and post the log?

[eran moyal]

 The box doesn't Cisco Gateway.

i dont access to box.

Perhaps, you should try setting 'RFC2833' first in the CUCM SIP Trunk or 'No Preference.

You can collect CCM Traces and check what is the DTMF negotiated between CUCM & the Box.

I change setting and DTMF doesn't work.
