Disconnect in the middle of calls

I’m using an asterisk 1.4 with TDM2400p (4 FXO/20 FXS) in our local pbx and often get a
complain from user of disconnection in middle of the calls. I’ve notice in my logs that all the reported
disconnected call has these message " [2010-03-03 17:17:07] DEBUG[4557] chan_zap.c: Something changed out on 146/0 to 125/2, returning -3 to restart " . This happen both inbound and outbound calls.

Here is the sample logs of the call leg…

Regards,
Piker M
