[Asterisk-Users] IVR Load

[WipeOut]

Hi,

Thinking about an IVR application and trying to get a handle on the best 
way to structure it so that the maximum number of concurrent calls can 
be achieved..

If the voice prompts were stored in a GSM format and were being played 
out through an IAX trunk that uses GSM compression would asterisk do a 
decompress/compress on the audio or would it simply pass through the GSM 
encoding?
Obviously if I could eliminate the decompress/compress activity is would 
make the server far more scalable..

Thanks..
