[SIPForum-discussion] Query for Time T4

[lakhan patel]

Hi All,

I have doubt about T4 Timer and what happen if any dialog is in terminated
state and other side tries to communicate with previous dialog which was
terminated?

After INVTE from A to B, B sends *404 Not found* and B received *ACk *for *
404* but when A-side receive *404 *and send *ACK *for *404 *Call goes in *
Confirm* state and after *5second(T4 timer fires) *it goes under *Terminated
*state and after that if we are sending Re-send *ACK *for *404 *it should
reply with *408 Call leg does not exist*.

*Can Any body tell me is it correct call flow or not?*
