Hi
I am facing some issue with my SIP trunk.
My setup is like CUCM > Router>ITSP link.
I am able to make outgoing call but when after a call i am dialing a pin from my CUCM ip phone which are SCCP phone the digit are not getting passes to the service provider.
My CUCM ver is 7.0
Plz let me know what to look for and also if any configuration example document you have plz share the same.
what all command shall i look for so that we can check what digit are getting dialed in the router.
Any help will be appreciated.
Thanks

Ask you ITSP: do they support DTMF relay ?

Hi
The image that i am runnig on the router is c1841-advsecurityk9-mz.124-3g.bin.
The isp support dtmf relay.
What else can be done

Which type of dtmf-relay do they support ?
02-10-2010 04:18 AM
they support dtmf signalling RFC 2833.
Also the call is gettig established but it is not passing those digit.
there is no voice related config in the router.
Also i have configured the same standard RFC2833 in the sip trunk configuration and kept the media termination point enable.

So router is not involved in telephony.
Check CM settings.

Is in trunk i have enabled media termination point
CUCM has its software MTU registered
dtmf signalling method is rfc 2833 in the sip trunk config.
what else can be checked,

Does the SIP trunk belong to the Media Resource Group List in which the MTP is in?
