MGCP PRI-Back-to-Back

Hi,

Router1(mgcp)--E1(cross--(mgcp)Router2--CCM(4.1(3)sr4). Router1 E1 & Router 2's MGCP gateways are registered to CCM. show isdn status display "multiple frame established". controller configuration on both end is pri-group timeslots 1-3,16 service mgcp.

Problem I'm facing here is, when phones behind Router2 calls phone behind Router1, debug isdn q931 on both router shows "no circuit/channel available". I've tried changging B-channel order selection, but same results.

Any pointers?

Thanks

If you configure the full E1, same results?

Make sure you have configure the following:

Try Top-down...

Re: MGCP PRI-Back-to-Back

You may have to do it as CAS connection, and yes change make one Top down and the other bottom up.
