Hybrid PBX

A hybrid PBX is a traditional PABX which mostly uses traditional analogue or digital phones, but which has been expanded (usually by plugging in an additional, costly card) to allow it to communicate using the SIP IP-protocol. This allows it to connect to IP phones or to connect to a remote IP system. In addition this supports clients with a multitude of various cabled infrastructures giving them the ability to merge old and new technologies.

A hybrid PBX has many of the same great features you can expect from VoIP services, including call rules, auto-attendant, and hold queues. The hybrid PBX also has the capacity for virtual conference rooms, fax over IP, and videoconferences. The hybrid PBX also can do SIP trunking. The most important feature of the hybrid PBX is that if either the legacy PBX or the VoIP server isn’t working, it automatically switches over to the other network.
