Ok gents I have an odd one here......

Have a SV9100 thats using and PRI for trunking and has and 8-port analog blade. Eveything seems to be programmed correctly, you can dial into the fax and it will pickup and receive, but if you go to dial out you get a busy. Tested with buttset and same thing, busy right when it goes off hook. any ideas would be great because im racking my brain on this one.........
