I am using a T serv 2, I did switch it out with no change. This problem just started out of nowhere one day it worked the next it started dropping. Which of coures points to the carrier. I am working with MCI here if that tells you anything. Verizon has checked and laid the blame square on MCI, What gets me..no errors on the T-1 screens no slips no alarms, the 228 see's nothing wrong and the busy signal I get when these calls drop. On the Executone you get dead air if the system drops it in most cases. Sometimes on an outbound long dist. call I get the busy signal and the "C" screen shows the call connected.

Thanks
