What is the best codec to use?


I want to implement FreePBX in my platform. In general, I’ll use 1 canal (in&out) calls and my bandwidth available to this is 100Mbps. So, What codec is recommended?


It doens’t matter. Your bandwidth is overkill for a single call.

The default ULAW/ALAW takes 100k

The standard codec that is used for calls to the pstn is G711.

For internal calls you can use G722, which sounds noticeably better than G711.

That is what a lot of people do.
