we have a location with a fiber nam. Autoattendant answers all calls, pots lines (6). Frequently, maybe 1 out of 15 calls will be answered directly into a users' mailbox, not the autoattendant. In the past we've rebooted the unit to resolve the trouble but it still returns, sometimes the same day. the trunks do not ring on any phones, they appear only.
what shall we do? Could it be a programming issue?
