+%global _description\
+This ia a RFC3261-compliant Session Initiation Protocol (SIP) Back-to-back\
+user agent (B2BUA) server software.\
+\
+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. 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.\
