Intercluster trunk between cucm and cme

[cigalahgroup]

Hello,

       I have CUCM 9.0 in my head officed  and CME 4.0 in BO. I have create the ICT from my CUCM and the call flow works fine form HO to BO. 

               I  know CME doesnt supports Inter Cluster Trunk so I have to make the dial peer on the CME, can any one help me sharing the template how to do it ?

Its very simple.

dial-peer voice 1 voip

decsription inbound dial-peer for calls from cucm

incoming called number.

no vad

dtmf-relay h245-alpha

dial-peer voice 2 voip

destination-pattern xxxx (where xxxx=your cucm extension pattern)

session target ipv4: y.y.y.y (where yyyy=cucm ip address

decsription inbound dial-peer for calls from cucm

incoming called number.

no vad

dtmf-relay h245-alpha

dial-peer voice 2 voip

destination-pattern xxxx (where xxxx=your cucm extension pattern)

session target ipv4: y.y.y.y (where yyyy=cucm ip address

dtmf-relay h245-alpha

Dial peer 1 is to receive the calls from CUCM and dial peer 2 is to send the calls to CUCM. If incase the call doesn't work after those configurations, please collect the following debugs Debug voice ccapi inout Debug h225 asn1 Debug h245 asn1

When I am trying to put the command

 incoming called number.  

Incorrect format for E.164 Number
        regular expression must be of the form  ^[][^0-9,A-F#*.?+%()-]*T?(\$)?$

Don't forget to add h323-gateway voip bind srcaddr <ip address>  to the interface of CME.
