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 sedwards at sedwards.com Voice: +1-760-468-3867 PST Newline Fax: +1-760-731-3000

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.
