asterisk users - Dec 2004 - what the heck? codec_gsm.c:135 gsmtolin_framein: Huh?

I park a call and instead of the parked extension
being returned, I get silence and the log shows
a bunch of the following messages

WARNING[26220]: codec_gsm.c:135 gsmtolin_framein: Huh?
A GSM frame that isn't a multiple of 33 or 65 bytes long from
(null) (320)?

what does this mean?

BTW these messages are intermittant. sometimes it works fine
other times i get the above message



Regards
Greg Cirino
