CHAPTER 18
Outbound Line Group
This chapter shows you how to manage outside lines on the X6004.
18.1 Outbound Line Group Overview
The following diagram shows the X6004 connected to three possible types of outside
connections:
• FXO Trunk (A): shows the X6004 connected to the PSTN (Public Switched Telephone
Network) via an FXO port on the X6004. You can also use the FXO ports to connect to a
traditional PBX, if your organization has one. You must have an FXO interface card
installed on the X6004 to configure these connections.
• SIP Trunk (B): shows the X6004 connected to a SIP server at your VoIP service provider.
You can use the SIP trunk to connect to a SIP server 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.
Figure 141 Outbound Line Overview
The outbound lines define a connection between the X6004 and PSTN, ITSP or your trusted
peer. To make calls from extensions on your network you still have to define LCRs, which are
outbound dialing rules (See Chapter 20 on page 185). You also have to configure an auto-
attendant to handle the forwarding of incoming calls (See Chapter 19 on page 175).
