[Asterisk-Users] size and quality of audio clips effect the playback??

[Gabriel Afana]

Hi,
    I've been having issues with asterisk playing back recorded messages.
They sound clear..but there are lots of breaks during playback (like its
losing packets).  I got top-end hardware and I'm on a killer network so its
not that.  I've talked over my SIP line using a regular telephone and it
sounds great, so its not the VOIP provider.  Asterisk is working great with
no other problems.  So I'm thinking one of two things:

More Obvious:  The other thing I noticed is I get a warning on asterisk when
I start the console saying the chan_oss it requested 8000 Hz but got 48000
Hz -- sound may be choppy.  I am using the onboard sound card.  Does
Asterisk use a sound card to play the audio over VOIP or is sound card only
needed if I have a physical phone hooked up to the computer?

Less Obvious:  Will the size and quality of a GSM audio file effect the
playback?  all my files were converted from wav files (22k 16bit stereo) to
8k mono GSM....the sound quality is fine, its just playback is choppy and
wondering if playing with the actual GSM file format would change anything.
