CUCM 9.1 SIP trunk to ISDN GW 3241

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.

Ahmed

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

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.
