Howto convert files from gsm into alaw?

[Hauke Hoffmann]

Hello,

I'm searching for a way to convert the prompts from gsm format into alaw.

I have german prompts from [1], but each file type is gsm and my
callweaver-box, cisco phones andd berofix-card uses alaw (G.711)

I know, there is a "file convert" command[2] in asterisk 1.4, but in my
version of callweaver (CallWeaver 1.2.1 SVN branches/rel/1.2 r5716) this
didn't work.

Does anyone know, how I can convert these files now?

Best Regards
Hauke
