Sippy B2BUA is 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.
