Hello! New to this forum as well as PBX system.

Currently Mitel SX-50 misbehaving after a recent thunder storm power outage.

Now, the PBX system rings all incoming call to a x210 and at the main console at same time. Also, same things happens if I transfer a call to any extension withing PBX and it will ring x210.

One other weird problem is that the PBX has x405 used for fax. The line for fax gets a dial tone but it doesn't break after hitting 9 for outside line.

The Alarm lights came on the first 24hrs after the initial problem and it read: A22 0031 Line Loopback Error 02/15. Now the Alarm light comes on only once in a while after I called AT&T cust service and a tech verified the connection upto the demark point.

Any help is appreciated.

Thanks!

Sam
