asterisk users - Nov 2006 - Digium TE405P dtmf issue

Hi Group,

    I have an asterisk running as media gateway with a Digium TE405P 2nd Gen rev
2 with echo cancellation. It is interconnected to a telco carrier via ISDN Pri.
The voice quality is clear except that sometimes a hear a beep sound that occure
around 5 to 10 secs in the middle of the conversation. When I check the logs in
the asterisk, I found this.

Nov 30 00:48:38 DEBUG[27705] chan_zap.c: Exception on 17, channel 5
Nov 30 00:48:38 DEBUG[27705] chan_zap.c: Got event Event 131121(131121) on
