in some hybrid codec scenarios, Ive seen people suggest Signed Linear.. this saves transcoding from PCMA to SLIN then to G729 for instance.. On 27 February 2012 11:09, Steve Underwood <steveu@coppice.org> wrote:

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 I'm shocked. You don't want to store your prompts in a wideband format, and be prepared for the future? :-)
If you have a pure E1 system, use PCMA. That is the codec for E1s. GSM will give poorer quality and require transcoding.
