Hi,

Please check the section "A Simple Two-Node Topology with H.323 " of the following CME guide which explains various scenarios of interconnecting two or more CME sites.

Hi manish,

should the ISR be CME or SRST

[Manish Gogna]

Hi Edwin,

This documentation is specific to CME.

YES.  It pretty much boils down to creating dial-peers on both CME routers pointing to each other, with  patterns that constitute your internal number ranges.

hi dennis,

Can you confirm if we use CME in riyadh and CME in Egypt (both sites having CME not SRST license), and both sites are connected together.

Will the user in riyadh will be able to dial an extn in egypt

[Jaime Valencia]

Yes
