[SIPForum-discussion] Invite Client Transaction

[Sumeetkumar Bhardwaj]

Hello Mahee,

Could you please let us know which part of ICT you didn't understand? . The timers are used for UDP mode which control the retransmission part of ICT.

Also you can read article from the site below:

Subject: [SIPForum-discussion] Invite Client Transaction

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
