Source note · Codec selection and bandwidth planning
G.722 audio is sampled at 16,000 Hz, but its RTP clock rate is 8,000 Hz. RFC 1890 assigned that value in error, and it is kept for backward compatibility.
Checked 2026-09-24
the RTP clock rate for the G722 payload format is 8,000 Hz because that value was erroneously assigned in RFC 1890
