18.1 Overview

This chapter shows you how to manage outside lines on the X6004.
The following diagram shows the X6004 connected to the various types of outside
connections:
• FXO/PRI/BRI Trunk (A): shows the X6004 connected to the PSTN (Public
Switched Telephone Network) or ISDN (Integrated Service Digital Network) via
an FXO/PRI/BRI port on the X6004. You can also use the FXO ports to connect
to a traditional analog PBX, use the PRI port to connect to a primary rate
interface, use the BRI port to connect to a basic rate interface, if your
organization has one. You must have an FXO/PRI/BRI interface card installed on
the X6004 to configure these connections.
• SIP Trunk (B): shows the X6004 connected to a SIP gateway at your VoIP
service provider (ITSP: Internet Telephony Service Provider). You can use the
SIP trunk to connect to a SIP gateway on which you have an existing SIP
account.
• Trusted Peer (C): shows the X6004 connected to another X6004 (for example,
at your branch office). You can establish a trusted peer connection with another
SIP server that lists your X6004 as a trusted peer.
