[SIPForum-discussion] Invite Client Transaction

[mahee max]

Hi,
can anybody elaborate me on the ICT(Invite Client Transaction), I have read
it in RFC 3261, but I find it bit more difficult to understand, since they
mix both reliable and unreliable transports with lots of timers and stuff. I
really got confused and lost.

Since I am only concentrating on unreliable  transport i.e UDP, can anyone
give a brief description of how ICT works for UDP, for example like a small
flow diagram or something like a skeleton of a piece of code.

Regards
