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. Unlike PBX-type solutions such as Asterisk for example, +the B2BUA doesn't perform any media relaying or processing, therefore it +doesn't introduce any additional packet loss, delay or jitter into the +media path. + +The Sippy B2BUA is distributed under version 2 of GNU Public License (GPL). |
