Hi, I am having troubles conncting 2 sites' PBXs. let's call them site A and Site B. the symptom is that when we make a call there is ringing but on the line you hear nothing (or quiet noise). you don't even hear dial\\busy tones. the session is termintaed by itself in 2-3 seconds.
The problematic site is site A. (I now that because site B is currently working fine with other siteC . therefor, i know that the connection to the pbx on site B is ok. on site B we have 3845 router with full E1 and NM-HDV2 ) .
On problematic site A there is 2611XM router installed with the IOS as follows:
System image file is "flash:c2600-ipvoicek9-mz.124-10.bin" Cisco 2611XM (MPC860P) processor (revision 4.1) with 125770K/5302K bytes of memory. Processor board ID FCZ100572MC M860 processor: part number 5, mask 2
2 FastEthernet interfaces 2 Channelized E1/PRI ports 32K bytes of NVRAM. 32768K bytes of processor board System flash (Read/Write)the connection to the pbx is done through cross E1 cable with NM-HDV card with PVDM-12.
here is the configuration file :

here is the log from the router after initiation a call: Mar 9 02:08:21.922: %ISDN-6-CONNECT: Interface Serial1/1:1 is now connected to 204 N/A
