Hi Charles,
Thanks for the clarification.

I have some (may be very basic) queries:

- What is the basic difference between transaction/request AND calls?
- Why sipp is not considering sending of INVITE as a call establishment 
process?
- How does people typically deal with such issue OR is it that I have
unique situation here?

Thanks for all the help.
