I spoke with Telecomtech1 on Sunday. He took a Tadaran pbx to his site and the problem could not be duplicated. When I first installed my customer about a year ago we had a T-1 in it and problems. Vertical said to have the switch settings changed to dms100 or something because it would work better. Then we swapped out to a PRI. I can not find anything from Vertical about what switch to use. Last Friday night they said they are going to send me a PRI card and as of Wed I have yet to see it. I will call on Thurs to find out that ball got dropped.
