[Freeswitch-users] playback terminator

is there any playback terminator for phrase macros? e.g. when you do: <action application="phrase" data="saymoney , 2.31"/> or <action application="phrase" data="timeleft , 33"/> I'd like to make FS stop playing on any pressed digits... something like: <action application="set" data="playback_terminators=#*0123456789"/> but seems not to be working ... any ideas ?
