Ok, thanks. I should have asked this in the first place: what I'm really getting at is that I need to record (or convert) prompts in many languages. I have a number of Windows based tools to do this. I want to end up with prompts that asterisk can play with the least CPU effort, ie. without transcoding. Would this be the gsm format? If so, it sounds like I should record in Wav format, 8-bit samples? How to convert to gsm?
Thanks again! Scott Scott M. Stingel Emerging Voice Technology Inc.
