Hi, folks, Now, most SIP system uses B2BUA?
If we do NOT use B2BUA, can't we prevent re-trasmitting of 200 OK? That is to say, if we do NOT use B2BUA, we need much time to receive ACK for 200 OK, especially in Internet. Then, we have re-transmitting of 200 OK. The solution of that is B2BUA. Accordingly, most SIP system ( though Internet) adopt B2BUA. Am I right?
