asterisk users - Feb 2008 - logging the estimated RTT using SIP

Is it possible in Asterisk 1.4 to log by somehow the estimated roundtrip
time (RTT) between server and some peer, which Asterisk computes based on
the sending of OPTIONS and the receiving of the responses to those OPTIONS?

Regards,
Ricardo Carvalho.
