not sure if this helps at all, but I have the same symptoms when I connect a PRI to a Nortel. The fix is to use the hidden command "isdn flip-chan-flag" on the interface.
Hope this helps!

Subject: [cisco-voip] Problems with 2811 as H.323-Gateway, CCM 4.1
Hello,
I try to configure a Cisco 2811 with VIC2-2BRI-NT/TE and a PVDM2-16 to act as gateway between our CCM and our PBX.
We had a test-equipment in July 2000 for 6 months with 2600 and a CCM 3.00, and it worked with the following config (see below).
Now I tried to get the 2811 working with a new CCM 4.1, I know it is a different config, but no success, and after hours and hours of
reading, I don't know any further... I think I read every single CCO-Document ;-).
When I turn on a "debug isdn q931" I can see that an IP-Phone-Call (8200-->1234) reaches the router,
but will not be forwarded to the PBX (Cause i = 0x85B2 - Requested facility not subscribed).
When I call an IP-Phone (8200) from the PBX (1234), the call reaches the router, but will not be forwarded
to the CCM (Cause i = 0x80A2 - No circuit/channel available). Debugs see below.
We have a CCIE-Voice-Consultant here to help us next week, but I want to get this work, that I can play around a little bit.
The rest works fine, CCM 4.1, 7912, 7940, 7960 with 7914, ATA with analog phone, SRST-Fallback, Phone Services,
Global Directory and all the stuff, but this router.....
Sorry for the "newbie"-question, maybe you can help me or point me to a newbie-discussion/forum.
Thanks in advance and have a nice weekend,
HP
