Hi Please find the required usage and difference of B2BUA with respect to proxy as mentioned below:-
The B2BUA is a SIP call controlling component. Unlike a SIP proxy server, which only maintains transaction state, the B2BUA maintains complete call state and participates in all call requests. For this reason it can perform number of functions that are not possible to implement using SIP proxy, such as for example accurate call accounting, pre-paid rating and billing, fail over call routing etc. regards Abhishek Dhammawat Aricent -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Vito Korleone Sent: Monday, February 23, 2009 10:22 PM To: [email protected] Subject: [Sip-implementors] B2BUA vs Proxy with Record Route Hi everybody! I 'm a new member in this group of SIP people :-). So, here's my question, Why "we" need a B2BUA?? Can't we just have the same functionality if we replace him with a proxy and insert the Record Route field to trace all messages between the subscribers?? thanks, Nikos ___________________________________________________________ Χρησιμοποιείτε Yahoo!; Βαρεθήκατε τα ενοχλητικά μηνύματα (spam); Το Yahoo!
