Hello list, I have got an asterisk box installed working ok with an b410p card to make and receive isdn calls. All works ok, but when a call is answer and the person starts to speak, always I can ear a "beep" during the call. This beep is ear some times in about 30 seconds between each beep. Pasted bellow I send /etc/misdn-init.conf and /etc/asterisk/misdn.conf Any clue will be apreciated. Thanks.
