[OpenSER-Users] How to account INVITEs and not "200 OK"s?

BTW our Cisco gateway sends Start exactly then INVITE arrives.

Actually all I need is to make sights of redirected calls. For example
if UserA calls UserB and UserB wants to redirect all calls to UserC
and UserC redirects all calls to UserD in case of failure etc.

The main problem is that if I make a huge number of rewrites or RURI
all I can send to RADIUS in Start-message is a combination of
from-uri, to-uri and request-uri. All intermediate steps will be
completely lost -  - in the upper example RADUIS won't know anything
about UserC. That's not good fo me.

To resolve this problem I initially decided to log all INVITEs even
they and the best way to do so is to mimic the behavior of Cisco which
sends Start-messages on each INVITE and not on 200OKs.

Maybe there are other ways to keep information about previous
Request-URI in the body of SIP-message?
