tdm04b incoming calls fine, outgoing VERY WEIRD

Incoming calls work fine. Outgoing calls ring the destination out on PSTN… when the destination answers, the calling party continues to hear ringing AND the party whom they called! Furthermore, the called party also hears the ringing. The call then drops with the timeout parameter is triggered in Dial.

Using asterisk 1.7.2.1, zaptel 1.2.5, and Wildcard TDM400P REV I Board 1.

Thanks!
