Has anyone had a problem with volume spiking up after 2-3 min of conversation, this is a Nortel Opt 11 with a t-1 trunk feed also 4 remote sites linked by t-1's. All sites and main Opt 11 have this problem, oldtelman
That has already been tried and I'm not fully confident that they can effectively test end to end without coming on site but they are. I am looking at ordering a tmdi or t-1 card and clock controller but I don't feel that confident.
