[asterisk-users] Asterisk G722

[SIP]

 From the RFC:

"Even though the actual sampling rate for G.722 audio is 16,000 Hz, the 
RTP clock rate for the G722 payload format is 8,000 Hz because that 
value was erroneously assigned in RFC 1890 
<http://www.faqs.org/rfcs/rfc1890.html> and must remain unchanged for 
backward compatibility. The octet rate or sample-pair rate is 8,000 Hz."
