[Sip] History-Info vs Diversion

[Sigrid Thijs <sthijs at androme.com>]

Hello,

I'm taking a closer look to SIP extensions that keep track of call 
diversions. Both the History-Info and Diversion header seem to be valid 
candidates.
I found the following documents defining these extensions:
- history-info: draft-ietf-sip-history-info-06.txt, expires July 17th, 2005
- diversion: draft-levy-diversion-08.txt, expires February 25,2005
What is the current status of these extensions? Is there still being 
worked on, are there new drafts on the way?

kind regards,
Sigrid Thijs
