[reSIProcate] support for PRACK(rfc 3262)

[Basavaraj Puttagangaiah <basavaraj.puttagangaiah@xxxxxxxxx>]

Hi all

I am trying to implement offer/answer model using PRACK.
I am using resiprocate-0.9.0-5019. According to documentation there is
no support for  PRACK in this release. 

But in old "reSIProcate" mailing list(around Nov 2004) i could see
discussions regarding implementing support for PRACK.
When will this implementation be available? 
Has any body already implemented this for resiprocate and is the
reference implementation available?


Thank you
  Basavaraj
