that's right - calling and called parties are both registered to same cucm cluster. Thanks for tip with OnNet and OffNet. I'll look at this in detail.
I think, Route Pattern '8000' can be created and put in Partition_1, that listed 1st in existing CSS, but then it should go to any gateway and return back to CUCM.
On Gateway config page u wil need to configure CSS for inbound calls without Partition_1, so call will go to CC.
So it will be difficult Dial Plan.
Why don't you want tot try change Calling Party Number Type from Cisco CallManager to any other in Translation Pattern?
Mat be it will be treated as offnet call?
we are facing a similar issue . All internal calls are routing via E1 PRI hence we are being charged by service provider for IP phone IP phone calls .both calling and called parties are registered in the same CUCM .E1 PRI is terminated to an H.323 Gateway .what need to be done for this ??
