Hi Everyone, I have couple of basic questions regarding SIP session setup 1) is it compulsory for UAC to REGISTER to SIP server before session setup? 2) does SIP server checks if the UAC is REGISTERED to the SIP server if it has received an INVITE request from a UAC? If yes then how SIP server handle to the INVITE requests from unregistered UAC?
