Page disconnecting calls

For some odd reason, out of the blue no less… pages will disconnect calls.

It will happen to more than one person at a time. I’m using aastra phones (57i, 9133i) FreePBX and asterisk 1.4.20.

It never used to do this, and the logs don’t really tell me much about it. Any ideas? Anyone else had this problem?

What version of the firmware are you using on the phones. There was a known bug with the Aastra 9133i phones in a previous version of the software doing this.

using the newest firmware for 57i and 9133i phones. for 9133i
57i is the one that was just released a few weeks ago.
