What codecs does Zipier Phone System use

Answer. Zipier's default codec is G.722.

All calls on Zipier Phone System use standard SIP.

G.722 uses not much bandwidth at 80 kbit/s and great audio.

You can also use G.711's PCMU (U.S.) or PCMA (non U.S.) (same bandwidth at 80 kbit/s and acceptable audio).

You can learn more about the bandwidth requirements of these codecs at 3cx.com/blog/docs/bandwidth-utilised-for-voip
