asterisk users - May 2005 - TDM zap channel Exception on 15, channel 1

Hello everybody.

I have an customer asterisk 1.0.5 running well since 3 monthes, 2 TDM 
cards 4 FXO, 4 FXS. Since one week, unable to pass call between Zap and 
Sip getting the "exception on 15, channel 1"

The * box is connected to an eads PBX and it seems that failure started 
when they make some changes on the PBX. Have someone an idea and what is 
causisng this failure? Here are the logs, the SIP phone is never ringing.

Connected to Asterisk 1.0.5 currently running on inet-tel (pid = 1223)

inet-tel*CLI> verbose 5

No such command 'verbose' (type 'help' for help)

inet-tel*CLI> set verbose 5

Verbosity was 0 and is now 5
