• LCRs (LCR is the outbound dialing rule) - When you create links from an
outbound line group to an LCR, you allow incoming calls from that outbound line
group to make outbound calls via the outbound line groups configured in the
LCR. For example, someone calling from outside your organization can use the
X6004 to forward their call to another outside line.
In the following example, outbound line group TrustedPeer is associated with
LCR1. LCR1 is comprised of two outbound line groups: a SIP trunk to your VoIP
service provider - ITSP and a connection to your local traditional telephone
company - PSTN/ISDN. Calls coming in via the TrustedPeer connection can
use the ITSP and PSTN/ISDN connections to complete their calls.

• Ring Groups - Links from an outbound line group to a page or hunt group are
known as a ‘ring group’. You can allow calls coming in via that outbound line
group to call the page or hunt group configured within the ring group.
In the following example, outbound line group Sales is associated to Ring
Group A. Ring Group A consists of:
• Page Group 1: allows you to call all the extensions within Page Group 1
simply by dialing the page group number (888).
• Hunt Group 1: allows you to call extensions within Hunt Group 1 based on
the algorithm defined in the hunt group setup simply by dialing the hunt
group number (999).
All calls coming in via the outbound line group ITSP can call Page Group 1 or
Hunt Group 1.
