Unless you are using the gsm codec close to exclusively on the wire,
there is no important reason to use it for the on-disk files.

Try to get your AE to save them as mono 16bit signed-linear wav files.
He should understand that and be able to do so.  

This will save the decode from gsm step when playing those files.  It
will also slightly improve the quality when compressing to some other
codec.  Especially if it is one of the lower bandwidth codecs.

(If you are only ever sending the files out over zap channels, the
best file format to use is ulaw or alaw as applicable to your area.
But that may be as difficult to get from your engineer as gsm.)
