[Freeswitch-users] ivr script, originating a call

Hello I'm launching a javascript that originates a call to a user and then records a file. The problem is that the soundfiles ("record after the beep" and "message saved") sounds strange (choppy/vibrating, yeah I know, sucky explanation). The same phrases sounds fine when played for an incoming call. Is it a bitrate issue or something like that? Regards, Jonas
