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

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