[cisco-voip] ISDN q921 error

[Ruben Montes (EU)]

Hi,

 

Problem was fixed adding the mgcp bind commands. 

 

 

Now my problem is that if I configure a route pattern to go through this
trunk, I get this error doing a 'debug isdn q931':

 

Jan 31 10:54:52: ISDN Se0/0/0:15 Q931: TX -> SETUP pd = 8  callref =
0x0002

                Standard = CCITT

                Transfer Mode = Circuit

                Transfer Rate = 64 kbit/s

                Plan:Unknown, Type:Unknown

Jan 31 10:54:52: ISDN Se0/0/0:15 Q931: RX <- RELEASE_COMP pd = 8
callref = 0x8002

        Cause i = 0x81D2 - Identified channel does not exist

 

Any idea?

 

Regards,

 

Ruben

let's try a little different look.  what does 'debug ccm-manager
backhaul' give with mgcp config?

 

MGCP 'registered' is a little different from successfully bringing up
the TCP session for q931 backhaul to tcp:2428 on CM.

Yes, it is registered. I've tried with H323 and works fine. Maybe an
issue with the IOS? It seems the router doesn't negotiate with the PBX.

I'm not very familiar with qsig trunking so I could be way off buIt
sounds like d-channel backhaul is not working.  

If you do a show ccm-manager, are you registered to the call agent?

Hi,

I've got this error configuring a trunk E1 qsig between Cisco 2821 MGCP
and MD110 BC9. It seems the router doesn't respond to the sabme
packets... ANy idea? Maybe a hardware problem? 

The controller E1 is up with no alarms and isdn status TEI ASSIGNED.
