if i start Record(...) in my extension, i can't hear the 'beep', which signals starting record. on asterisk cli i can see, that it plays the file without any error. if i add a 'Playback(beep)' before Record(), asterisk tells me the same and i hear nothing too. with the command 'conference play sound channelX beep' i hear it on the related sip-phone. asterisk version is 1.6.1.
