Cucm to be connected with different cucme

[techguy]

I have one site where some ip phones are connected with our main cucm. But rest of the phones are created at local cucme (router 2951). Is it possible that 5 phones connected with CUCM can reach to local created phones???

Yes, on CME configure a voip dial peer to CUCM and on CUCM configure that CME as an H323 GW.

Can i configure inter cluster trunk between cucm and cucme ?

[Jaime Valencia]

No, that's for CUCM CLUSTERS only.

thnaks alot. Its much appreciated if someone can give me a template/example of how CUCM and CUCME (both cucm and router having cucme can reach each other via wan connection) can be inter-connected.

Do i need to create separate Router pattern, Router List, Route Group and Route Partition & CSS ?

On Gateway side, what will be the voip dial peer ?

Hi,

You can find this document as a guide to configure the CallManager:

http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_configuration_example09186a00808ebbfe.shtml

The dial-peer in the CME should be something like this:

dial-peer voice 1 voip

    destination-pattern xxxx

    session target ipv4:

    dtmf-relay h245-alphanumeric

    voice-class codec 1

Remember to add the h323-gateway voip bind srcaddr command under the interface that has the IP address that you configured in the CallManager.

Hope it helps, please rate if it does.

Regards,

- Adrian.

The ip phones configured on CME Router ( not on the cucm, their tftp server is itself that cme router ) can call to the ip phones configured on cucm ?

[Adrian Saavedra]

Yes, as long as:

1.- A dialpeer VoIP is configured in your router towards the CUCM (just like the one I put in the previous post).

2.- The CME IP address is defined as an H.323 gateway in CallManager and has a CSS assigned to reach the CallManager endpoints.

Hope it helps, please rate if it does.
