I am trying to setup video conferencing thru the Magix via PRI.. I have renumbered three adjunct numbers to reflect numbers within my DID range . I also programmed those adjuncts as 2B-data. The video conferencing equipment has 3 BRI jacks built in. I have made video calls up to 256K but can't get it to 384K. which the video equipment can handle. Has anyone done something like this before with a Magix system ?? If so, am I missing a step ??
