The interesting thing to check here is if you can place a call TO the phone while it's marked as UNREACHABLE. Unreachable means that asterisk has sent an OPTIONs message 7 times without getting a reply at all. If it's LAGGED, we've got a reply, but far too late. If we can't get multiple OPTIONs through, how can we get an INVITE through? /O _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
