Hello all,
I have a setup with CUCM 9.1, VCSC 7.2 and ISDN GW 3241 (2.3). I have created a SIP trunk. Between CUCM and ISDN GW. Voice calls are working fine but if I do a video call (I see the 6 b channels up as configured for 384k), the call setup is done but I fall to a voice call. So looks like discussion call capabilities fail. Codec?..
I was not able to find a step by step configuration document for such setup (CUCM - ISDN gateway 3241 SIP trunk).
Any one have an idea why video call is not working? any hints/comments/advise is welcome.
Thanks.

Hi,
I must configurer CUCM with GW 3241, can you please explain how you configured the SIP trunk + equivalent of search rule on CUCM
I'm agree I can't find any thing about configuration CUCM ISDN GW 3241
Thank you,

I would have thought you'd have the SIP trunk between the CUCM and the VCS. The ISDN Gateway would be register ed to the VCS. You wouldn't have a trunk straight from the CUCM to the ISDN Gateway. The search rules on the VCS-Control (or the dial plan prefix it's registered on) would then route the calls out the ISDN.
