Video calls over ISDN does not connect.

I got a problem. remote sites can video call me on ISDN but when i try and call them my link speed drops from 384k to 64k, and phone just rings, no answer. they dont even see my calls coming through to them. when they call me i get connected at 320k even though we bot have 384 (3x64k ISDN lines) Calling any where using IP on the same system is fine.

Re: video calls over ISDN does not connect.

I would check all your ports on the firewall. Test with a trusted user with all ports open. If that works, then you know you have to narrown the ports down.

How do I find the MAC Address for my Polycom ViewStation ISDN Video Conference?

I just called Polycom and the guy said it starts with 0003 or 0004. Sure enough I had one of those numbers, it was the same as the serial number on the box the phone came in. This number is found on a sticker on the back side of the phone. Easy to find, but not labeled as a "mac address"

Polycom ViewStation H.323 Red Blinking Light

Are you able to move the camera using the remote?
If not, then you may have a hardware issue.
If yes, then try to connect to the Viewstation (web interface) using its IP from a Computer.

Let me know what happens
