Summary:                    RTCP jitter incorrect
Description: 
RTCP IA jitter field seems to be calculated incorrectly. The code in
res_rtp_asterisk says:

rtcpheader[5] = htonl((unsigned int)(rtp->rxjitter * 65536.));

Where (rtp->rxjitter) seems to be calculated based on local time (instead
of rtp timestamps), so it's expressed in seconds. If that's true, then
(rtp->rxjitter) should be multiplied by (rate) instead to get the proper
value included in RTCP.

That's the case since 1.4 till the current svn-trunk.
