CallManager & CMExpress Interoptability

I'm attempting to get ip phones registered to a CallManager Server to be able to communicate to ip phones registered to a CMExpress router.

I can dial from an ip phone registered to the CallManager Server to an ip phone registered to a CMExpress enabled router.

However, the reverse does NOT work.

I've setup a DIAL-PEER VOIP on the CMExpress enabled router, pointing to the CALLMANAGER Server, but I just get a BUSY TONE when attempting calls.

I'm not sure if it's possible since it's sort of an IP to IP VOIP call, which is an issue obviously.

Anyone know how to get this working?

Thanks,

Paul

Re: CallManager & CMExpress Interoptability

Paul,

You should be able to place an H323 call from CCME to CCM. However this config is not supported currently because there are a couple of known issues. We will be releasing CCME Rel 3.1 in the next couple of weeks which will support H323 inter-working between CCME and CCM.
