Solved: CME to CME InterConnectivity

Sriharshaa Prabhakar · ‎05-07-2007

Hi Guys,

We have an existing CME Setup which is configured and running, we would want to add another CME on the same network that caters to another department in the office, however we want the DNs on each other to be reacheable by dialing each others extension.

We are planning to configure H323 Gateway by matching the dial-peers on each end, I would like to know is there something like an Inter Cluster type of configuration that we do on the CCM that can be implmented on the CME.

Setup

VG1(Gi0/0)----Switch-----VG2(Gi0/0)

Regards,

Regular voip dial-peers will work. You can setup something like this. Make sure the DNs dont overlap between the systems, otherwise you may have to use dial access codes like 8+<4digit number> of remote CME.

CME1

dial-peer voice 1 voip

incoming called-number 2...

dtmf-relay h245-alpha

codec g711ulaw

no vad

dial-peer voice 2 voip

destination-pattern 3...

dtmf-relay h245-alpha

codec g711ulaw

no vad

session target ipv4:

Mirror the config on the above dial-peers in the other CME router. With local DNs being 3XXX can dial-peer 2 with destination pattern 2...

If using CUE, remember to give hairpin commands such as

voice service voip

allow-connection h323 to h323

allow-connection h323 to sip

allow-connection sip to h323
