  • Atlas 550 with PRI to analog ports is showing a lot of the same Event Logs

    I am getting a lot of the same Event Log Errors saying: Call clearing: TIMER_EXPIRY : Loc=U, Category: Major, Source ISND, Port/Sublink 1. What is causing this? Atlas 550 with an incoming PRI and outgoing analog ports.

  • I have an Atlas 550 that I have configured three BRI slots to hunt, using the same number for In#Accept with incremented SPIDS.  Two questions:  First, is it possbile to have the last BRI in the hunt group hunt next to an FXS port in the box.

    Second, is it possible to have that FXS port call out when it receives a routed call from the hunt group?
