[Freeswitch-users] Voicemail recordings being cut off on the front end.

I need some direction on tracking down why some voicemail recordings are being cut off at the front end. There are instances where the start of the .wav file is a good 5 seconds into the intended message. what FS components could be responsible clipped voicemail recordings? is there silence detection going on? if so, are there any controls such as automatic gain control, fixed volume settings for recordings or other normalizing going on? any advice? thx.
