I highly recommend you report this go grandstream. I have already<br>
done so once and that was 6 months ago. I can't believe this problem<br>
still exists.<br>
<br>
While G722 is a 16k codec the SDP and clock should be at 8k. This is<br>
due to a bug in the RFC.<br>
<br>
RFC3551 section 4.5.2 clarifies this information.<br>
<br>
Even though the actual sampling rate for G.722 audio is 16,000 Hz,<br>
the RTP clock rate for the G722 payload format is 8,000 Hz because<br>
that value was erroneously assigned in RFC 1890 and must remain<br>
unchanged for backward compatibility. The octet rate or sample-pair<br>
rate is 8,000 Hz.<br>
<br>
Aastra also does G722 incorrectly.<br>
<br>
Snom and Polycom work great.<br>
