We are having an issue with a voice over ip architecture where basically we have one pbx on one end connected to a 3825 through a qsig E1 and same thing on the other end. Both routers are connected through the LAN since this is a lab environment before putting it into production.
The call goes through from one end but not from the other. It does go through if we initiate the call from the router instead of the PBX on the not working side.
While troubleshooting, we found the isdn error "invalid call reference value" and the L3 BadPeerMsg.
Apart from this, the configuration is straight forward with session targets and the call does get routed to the pbxs.
Please if you have seen this kind of error before, let us know how you dealt with it.
