Back-to-Back User Agent (B2BUA) enables the EdgeMarc to control all aspects of a call that are defined in a SIP INVITE request or in subsequent SIP methods that inherit the header contents of a SIP INVITE request. B2BUA provides the system administrator with the ability to finely tune the rules by which SIP traffic is distributed between a SIP Server and a PBX on your network.

Note

B2BUA is not available when Multi-port is enabled.
