I have a Polycom viewstation 512 which has not been used in about a year. IP calls work fine but ISDN is no longer working. We receive the following.
Cause No. 50 - requested facility not subscribed.
This cause indicates that the user has requested a supplementary service which is implemented by the equipment which generated this cause but the user is not authorized to use.
Local Telco tested IDSN and lines are good. The configuration got wiped out and we had to re-enter SPIDs and video #'s. I think maybe we are not entering them in the right order or menu. Is there a differen between ISDN #'s and Video #'s. PLEASE HELP

You need to have your ISDN BRI provider monitor/capture your D-channel to see what facility is being requested that they are not supporting on your line. You might also TELNET into your VS and capture the syslog messages to see if there are any clues there.

Thanks,
Its been a while since working with SPIDs and I knew I was missing something. I was able to get past this original error, however now it seems all 4 channels connect (all 4 spheres go green) and we say connected but the screen goes blue and no audio. I've tried down grading to 128 and we get audio but a blue screen with no video.
