I am trying to see if there is a way to keep a conference alive in SLA when the Shared Lines drop out of a call, i.e. call comes in, a shared line answers and then conferences out to a gateway or some other non-shared line using i.e. bgapi expand originate sofia/internal/2001@${somewhere} &sofia_sla(uuid_sharedLine) . (now three channels on the call) Presently when the shared line hangs up the entire call ends. I would like the two or more non-shared entities to remain conferenced. Bob McCarthy
