asterisk users - Apr 2006 - Problem with playing old gsm files

Hello,

I upgraded to 1.2 version and all of my old gsm files that I created by
converting from wav are not being played anymore.

this is my file characteristic:


[root@voip sounds]# sox -V closed.gsm -e stat
sox: Detected file format type: gsm

sox: Input file closed.gsm: using sample rate 8000
        size bytes, encoding gsm, 1 channel

Do I have to convert those files to different format?

Thx
