SCCP to SIP Calls

[Gerard McGrattan]

Hello Cisco Voice World

In my organisation all phones are running on SCCP.

I wish to pass calls from these to a 3rd party conferncing system via a SIP trunk. Will a MTP be required? Is that dependant on whether or not the 3rd party system support EO or DO?

Thanks for your advice.

If you are going to use Deleyer Offer then you shuld not need MTP unless there is DTMF compatibility issue in which case CUCM would insert it per call as needed. If EO is needed then MTP would get engaged unless you route the call via CUBE.
