We have an Asterisk 1.4.22 box with 2 PRI (5ESS). I’m using the server for IVR. There are a few IP phones used primarily for testing and when we go live, we will be strickly using PSTN.
I’ve recorded all of my system prompts in WAV format. Hard Disk space is not an issue but I would like to avoid having Asterisk do the Codec conversion “on the fly” for every call.
Could someone please explain if PRI actually uses a Codec?
Should I leave my prompts in WAV format or do a massive conversion before going live?
When a new prompt is recorded by a caller, should I record as WAV ?
