Chapter 4 XE IP PBX Configuration
4.1 XE IP PBX Overview
The XE IP PBX supports both session initiation protocol (SIP) and H.323
recommendation, and thus is suitable for complex networks deployed with both SIP
and H.323 devices. The XE IP PBX can serve as a location server (LS), a process
server (PS) and/or a media server (MS).
A PS can serve as an H.323 gatekeeper and/or a SIP server, depending on your
configuration. An LS can store the device and number information, and allow the PS to
query the information. An MS can provide media services and media processing.
