I have an axxess 4.4 that if I do a unsupervised conference with an inbound call on a t-1 to an outbound call on the same t-1 it works fine. but if I try to conference in bound t-1 to outbound pri card I lose audio. If I direct access the pri trunk group it works fine, its only when I allow the ars to route the call. Any ideas, I am thinking a timer issue?

thanks,
Ross
