My goal is one number (2) systems. CUCM and OCS.
Clearly, I can use RDP to setup and ring different extension on OCS. Incoming DID comes into CUCM x4000. x4000 has RDP setup to ring 4155553000 which is on the OCS trunk. Both end points ring.
I know dual forking has always been talked about where we could have x4000 ring CUCM device *and* and another device through the SIP trunk on OCS or another system. Has there been any changes to make this happen in CUCM 8.x or with newer IOS?
CUIMOC is my next suggestion and create shared line on CUCIMOC and my primary CM Device.
