CCME connect to CCM 5

Unanswered Question
Dec 13th, 2007

Hi All,

My Customer say that CCME can not trunk to CCM5, Is it True?

From My understanding,

as long as the dial peer on CCME is done, it should be ok.

Assuming CCME extension is 10..

and the call manager side is 20..

On the CCME

dial-peer voice 1000 voip

destination-pattern 20..

session target

dtmf-relay h245-alphanumeric

What Should be done at the CallManager Side? A trunk ?

Is there any more config that should be done at the CCME ?

I have this problem too.

I haven't tried this with this version of CCM, but it should work fine. It can either be done with a trunk or a gateway on the CCM side. Make sure the codec is the same on both sides or that there is a transcoder available. Also, on CCME, you will need an incoming dial peer for calls from CCM to CCME.

Hope this helps.

Curious, why is a incoming dial-peer be configure, for the simplest setup

Should not the dial peer be create in the CCM?

For incoming calls from CCM to CCME an incoming dial peer is required on the gateway. There are no dial peers created in CCM, only route patterns.

Adding your CME box as a H.323 gateway in CCM will be the easiest way to manage that connection.
