You can do it with a one-time conversion. This will require a single g729 license: *CLI file convert foo.wav foo.g729 There are embedded Astrisk distros like Astlinux that target small form factor hardware. They have distributed the standard prompts in various encodings for quite some time. I think that they may have been amonst the first to do so. Platforms like the Soekris Net4801 could only sustain a couple of G.729 transcodes, making native prompts a practical necessity.

Asterisk will attempt to use prompts encoded with the same codec being used for the channel. So, unless you have a channel that is using MP3, Asterisk would have to transcode the prompt every time it is used. Why would you want to burn CPU cycles for this useless activity? You should strive to have prompts available in all the channel encodings actually used by your system. I have systems that only use ULAW, so all of my prompts are encoded as ULAW. (Sometimes I cheat and use WAV files since they are easier to work with and transcoding from WAV to ULAW is cheap.) -- Thanks in advance, - Steve Edwards sedwa...@sedwards.com Voice: +1-760-468-3867 PST Newline Fax: +1-760-731-3000 ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- AstriCon 2009 - October 13 - 15 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
