HI!There , I have had customers change to Rogers Cable tel lines over the years ,, and sometimes the lines would get locked ,, rebooting was the fix ,, Sometimes i would change the Nortel Cics Trunk Programing to Short Pbx , and that seems to solve the lock up ,, but with the 3x8 dr5 ,,it hasn't that option ,, anybody run into this ,, i was thinking of turning on Supervised Disconnect ,, but not sure if it will cause any other issues.Any Ideas ,, Rogers cable is a Canadian provider. Thks
