[arm-allstar] WAV To GSM Converter?

[K0LNY ??]

Hi Group,
I saved my original node-id.gsm file, and I made a WAV using a TTS I like better, and tried an on-line wav to gsm converter.
I have nothing to use to test it in windows, but I sent the file via Teraterm to the AllStar and placed it in
/etc/asterisk/local and after saving the node-id.gsm to a backup, I renamed the one I made and converted to the node-id.gsm, and rebooted, and it did not play.
The IP address still came through though.
So I'm wondering if there is a better way to convert these to play what we want?
Thanks.

Glenn
