As noted, the RTCP patch set may provide this within RTP, but that 
patch is not complete .  However, certain devices (SNOM, Cisco 79xx 
SIP loads) may provide some data in the SIP headers which you could 
extract with the SIP_HEADER function.

There is also a patch which probably doesn't work/isn't necessary any more:

I seem to recall some discussion about making Asterisk provide these 
same statistics, which seems pretty easy since I'm betting the 
numbers are stored somewhere inside of chan_sip already...
