I believe I read on this mailing list that someone was implementing some
form of call quality metrics for Asterisk but I've tried searching and I
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.
I stand corrected, and should pay more attention to the SVN mailing
list. The RTCP patch was indeed committed to trunk back in June by
Olle, and I somehow missed putting that in my notes.
The values can be extracted in the dialplan, I assume at the end of the call:
${RTPAUDIOQOS} RTCP QoS report for the audio of this call
${RTPVIDEOQOS} RTCP QoS report for the video of this call
