In a perfect world we'd be using speex (compresses/sounds better than GSM, is BSD-style licenced so should work everywhere and is officially supported on Fremantle), but sadly asterisk doesn't have a format_speex.so yet :-(

In a perfect world we would use an open licensed compressed codec that came pre-installed on the majority of platforms.

This is the essence of my first query. While I want to be able to hear the voicemail on my n900, I also want to be able to hear it on any old machine that I happen across and can get to my email with. And the vast majority of those will be Windows, and will not have uncontained gsm or speex codec installed. They will however be able to decode wav49, as do most linux distros out of the box.

So the fastest if not best route to getting a cross platform compressed voicemail format for asterisk that will work with the n900 is to get the n900 to support wav49

What exactly is wav49? Can you point to a good source documenting it?

I think I have fount the problem as to why my .wav voice mails that arrive by e-mail wont play.

On my n810 I installed MPlayer and was able to play them with out a problem, don't now how to use the command line version of Mplayer and KMPlayer doesn't play my Voicemail .wav files.

Excuse my ignorance but cant a codec be added or included with something like the "Extra Decoders Support" Application?

I this any help

So glad I stumbled on this thread, I have been going nuts trying to find a solution to this problem. At least I now know there is no good solution available at the moment.

Hopefully the codec can be added to the N900.

Shouldn't we be adding a bug report or feature request to have the codec added?

Aah, perfect. Should have thought of this myself.

I just changed /usr/share/applications/defaults.list and modified x-wav to load up hildon-kmplayer.desktop rather than hildon-mediaplayer.desktop

Now wav files are loaded in kmplayer, and I have altered the player for these to mplayer and now wav49 voicemails work perfectly.

Thanks...

One already exists, feel free to vote for it (but please avoid "me too" comments).

How do you alter the player to mplayer?

Thanks in anticipation.
