Extension Mobility Cross-cluster Call routing

Guys,

Just have a quick query. In EMCC, for a visiting phone to be able to make calls to the PSTN using the visiting cluster's gateway;based on his home cluster dialling pattern or habit, do you have to configure the RP for the dialled pattern on the visiting cluster?

According to SRND, the EMCC SIP trunk CSS, performs digit analysis for the dialled number when the call is sent to it from the phones home cluster. The question is, the route pattern for the visiting phone is not define on the visiting cluster, how then does the call route.

With Emergency calls, you define the Visiting clusters pattern on the home cluster. Is this similar for all calls too?

Hi.

You have to define RP on home cluster to visiting cluster only if you want to use local pstn access of visiting cluster.

Emergerency call should ,of course, be routed to local pstn access.

Carlo,

Thanks for your response. From a desgin point. it looks like it is better to route calls using your home cluster pstn gateway because it can become quite unstainable to be defining route patterns for each cluster and countries in those cluster(s) that will visit a location. That loosk like a nightmare. So i tak eit that it is better to only use local PSTN for emergency calls only

Yes sure, in a multi site envirorment could very hard to define the route plan.

I followed the same thought.. only emergency calls via visiting PSTN

Regards.
