call routing and forwarding between to different CME systems

Unanswered Question
Jun 6th, 2010

I have a setup with two separate CME systems that can talk to each other using 3 digit extensions over a WAN link but each has its own SIP trunks for PSTN calls.  If a call comes into CME_A on its SIP trunk can it be forwarded to an extension on CME_B?  What about call routing?  Can an incoming call on CME_A over its SIP trunk be made to ring an extension on CME_B?

Thanks in advance,


I have this problem too.

Hello Diego,

That should be possible, the but you need to hardpin that call, because the TISP will not know the IP address of the second CME box.

Walter, could you give me an example of how I would do a hardpin for this?  I am not familiar with this technique.
