Sorry .. my mistake :) Got confused with the callee , caller terminology for a second .. Gautham's right we can send a BYE to an early dialog from the caller side and the early dialog can be cleared up after 64*T1 secs after the first 2xx .. Cheers , Sayan

I though section 15 says you cannot send a BYE from the caller on an early dialog just wanted to clear this up :) Markus , you have written the UAS sends a INVITE , I assumed that's a typo and you meant the UAC sends an INVITE am I right ?

And, it can clean up any existing early dialogs 64*T1 seconds after receiving the first 2xx response, per 13.2.2.4 Thanks and Regards, A. N.

The proxy forks the INVITE and two provisional response with different to tags are coming back.
