SX20 ISDN 3241 no video

[It Dep]

Codec cannot reconcile ande establish video with remote site trough ISDN Gateway. But my videophone can.

Where is configuration mistake?

In attach two debugs from ISDN gateway:

1.txt - sx20 call

2.txt - cisco videophone call

This is from SX20. What does it mean?

Hi,

I meet the same issue: no video using SX20 and ISDN GW. Fallback to audio works fine.

Did you resolve your issue?

Is there a bug regarding codec or ISDN GW software version?

Best regards

[Wayne DeNardi]

What software versions are you running on your SX20 and on your 3241? 

I've just tried one of my SX20s - Software version TC6.2.1, through our 3241 - Software version 2.2(1.79)P.  Both inbound and outbound ISDN connections worked correctly.

What is the remote endpoint you are dialling in to?  I know from expereince that some of the earlier versions of the TC software had issues negotiating the right video and this was fixed in TC6.2.1.

Did you ever get a resolve for this, did you downgrade software to the same versions as stated by Wayne DeNardi ?

I have the same issue, I have upgraded from TC7.2.1 to TC7.3.3 and the gateway is running 2.2(1.94)P

I have reset the SX20 to factory and still no joy? I have tandberg MXP's and Polycom VX8000 and other devices working through the gateway no problem.

All devices are running H323, all registered to the Gatekeeper that comes with the gateway and all using the same dialplan/codecs?

Hi,

In my case it was a Service Provider issue

Best regards

[Wayne DeNardi]

It works fine on the newer versions - there should be no need to downgrade.

We've got TC7.3.3 running on all our endpoints, IL1.1.4 on the ISDNLink and 2.2(1.99P) on the 3241.

All working fine.  If you're having issues with your ISDN, as the other poster suggested, get your ISDN Service Provider to check their end.

Thanks for the update, it must be a configuration issue as like I have said all other devices are working fine. It's just the SX20 that reverts back to audio only. I might try reducing the caps set on both the codec and gateway to see if it's a negotiation timeout.
