32.1.1 What You Can Do in this Chapter
Use the LCR screen to configure settings for your dialing rules for outbound calls routing. See
Section 32.2 on page 521.
32.1.2 What You Need to Know
The following terms and concepts may help you as you read through the chapter.
LCR
LCRs are made up of two components. The first part of an LCR is a set of 1 or more outbound line
groups (see Chapter 30 on page 477). The second part of an LCR is a set of dial conditions, or a set
of pattern of digits that distinguish each individual LCR.
LCRs define which outbound line group(s) that authority groups, trusted SIP peers or outbound line
groups can use to make an outgoing call. This is done via group management, see Chapter 33 on
page 526. Once you create an LCR, you can associate it with:
• Authority Groups - give all the extensions contained in an authority group the right to use the
outbound line groups configured in the LCR.
• Trusted SIP Peers - give the telephones connected to the SIP peer the right to call the ISG50
and then dial out from the ISG50 using the outbound line groups configured in the LCR.
• Outbound Line Groups - give anyone calling in via the associated outbound line group the right
to use the ISG50 to make calls via the outbound line groups configured in the LCR.
Outbound Line Group
The outbound lines define a connection between the ISG50 and PSTN, ISDN, ITSP or your trusted
peer. See Section 30.1 on page 477 for more information.
