MGCP doesn't work with CallManager 4.1(2)<-->1760. But why?

Hi

I'm experiencing troubles with Cisco CallManager 4.1(2) and 1760 router (IOS Version 12.3(11)T3) as a MGCP-gateway. I'm trying to get CM and 1760 to work with MGCP and have succeeded to establish some sort of connection between them (as shown in **debug mgcp packets**). Gateway Configuration in CM also shows "Registered with Cisco CallManager". 1760-gateway has been configured basically from the CM with some commands to router side also (**show running-config**).

My problem is that I have not managed to receive any MGCP packets other than these while trying to call through gateway (debug mgcp packets on) and the call won't go through (I'm using ISDN BRI port and line to connect 1760 to PBX and it should be OK.). I have also created a Route Pattern to CallManager and it should also be correct. Does anyone have any ideas about this? Why won't I see any other MGCP-packets? Why won't call get routed?

sh run, sh isdn status, sh int bri 0/1, debug mgcp packets and sh mgcp

-command outputs are attached.
