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).
