[Taduru Hariprasad]

Hi,

I started to learn sip. Currently going thru rfc 3261. Can i have th
answers for the
following doubts.

1) BRANCH and CSeq parameters will get change for every transaction?

2) How Ack is treated as one transaction if the final response is 200-ok for
   an INVITE?

3) How to detect loops and overcome them?

And also please mension/attach the docs if you have for my referrence.

Thanks
Hari
