Hello,
I have a Cisco CallManager 4.1(3), a Cisco 2821 and a video conference station.
In the video conference station, there are 4 ISDN ports. When you call the
station on its main port, other ports should open.
In my Cisco 2821 voice gateway, I have an EM-HD-8FXS/DID card with an expansion module
EM-4BRI-NT/Te. These 4 BRI should provide the 4 ISDN lines for the video conference station.
Here is the config of a BRI:
"interface BRI2/0
no ip address
no ip mroute-cache
isdn switch-type basic-net3
isdn overlap-receiving
isdn protocol-emulate network
isdn layer1-emulate network
isdn incoming-voice data
isdn bind-l3 ccm-manager service mgcp
isdn sending-complete
isdn static-tei 0
isdn skipsend-idverify
line-power"
A "voice only" call can be made from and to this station but I
can't receive any video when I call another video conference station.
Do somebody have any idea?
Thanks in advance if you can help me.
Rgds.

Check if any access-lists are affecting/restricting the Video trafiic. If so, you can reconfigure the same to remove the restriction.

IOS 12.4(11)T now supports termination of video calls on ISDN interfaces

Please note, H.323 and not MGCP is used, and the EM-4BRI-NT/TE is not listed as supported hardware, but it might be worth a try.
