For a start: 

* upgarde to the current release of 1.6.2.x
* does that message play when you call it without a forward (302) on your 
admin phone?
* convert the .gsm prompt to a .wav or .alaw or .ulaw prompt and see if 
that improves matters
* do a "RTP debug" to see if there is any RTP being sent at all
* consider ChanSpy for listening in (although I doubt that'll help you)
