I believe I read on this mailing list that someone was implementing some

can't seem to pull up anything.
Can someone please tell me what the proper name is for call statistics
collecting and what the status is of this effort in Asterisk?
If I remember correctly these statistics are collected in both
directions? The far end-point reports back statistics via SIP to the
server.

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...
