Module B2bua

This module is in charge of intercepting requests and routing them to the back-to-back user agent server.
Requests filtering is based on the "User-Agent" header value, thus 'b2bua-server/user-agent' values must match both on Proxy and B2BUA servers.

filter

A request/response enters module if the boolean filter evaluates to true. Ex: from.uri.domain contains 'sip.linphone.org', from.uri.domain in 'a.org b.org c.org', (to.uri.domain in 'a.org b.org c.org') && (user-agent == 'Linphone v2'). You can consult the full filter documentation here: https://wiki.linphone.org/xwiki/wiki/public/view/Flexisip/Configuration/Filter%20syntax/
