Hi,

I need one clarification on INVITE server transaction. 

After UAS gets INVITE, when TU sends 2xx response, then UAS immediately transits to 
"Terminated" state and gets deleted. From then onwards, TU will handle the 
retransmissions of 2xx response and its corresponding ACK. 

Now, if we assume that, after UAS receives INVITE, the 100 sent by it is dropped in 
the network. Similarly when UAS sends 2xx, lets assume that 2xx is also dropped. Since 
2xx is sent, UAS transaction is deleted. Since UAC has not received any response, it 
will again retransmit INVITE. Now, when this retransmitted INVITE comes to the 
destination, will a new server transaction be created. If so, how is this 
retransmitted INVITE handled?? 

Thanks & Regards
 Krishna
