Hi Anita,

As far, I have played with FS. I could notice that FS try to choose the format acording to the media, at least I saw this in my box. Someone from FS, could validate this. Recently, I loaded a set of mexican prompts, all them were in 44KHz format, when I tested, I notice in FS console, FS "converted on fly" to 8KHz.

It is a good idea to have your prompts in all formats (44, 32, 16, 8KHz, gsm, linear), if your box have enough space too keep all your prompts. However, each media have their own restrictions (not FS restrictions). In TDM world, PCMA and PCMU (the correct is u-law and A-law codec) are used. Other media like GSM and SIP/H.323 used other formats, including PCMA and PCMU. The best practice, is to avoid transcoding as possible, to not demand more processing resources.

Yesterday, I saw someone storing his audio prompt files in 44.1 kHz mp3 for playback !!! I am still recovering from the shock!

What will be the correct format to keep prompts in if we are connected via FreeTDM to an E1:

GSM or PCMA?

regards,
Anita
