21.1.2 Managing Outbound Line Groups

Outbound line groups include SIP Trunks, FXO Trunks and Trusted Peers as defined in
Chapter 18 on page
via these channels based on the outbound line group they are part of. You can manage
incoming calls by associating (linking) outbound line groups with:
• Authority Groups - When you create an outbound line group it is by default linked to all
authority groups created on the X6004. This means that calls coming in via this outbound
line group are authorized to call any extension created on the X6004. You can remove the
link from an outbound line group to an authority group to stop incoming calls from an
outbound line group from going to a specific authority group.
You must also configure auto-attendant settings before calls coming in from
outside lines can call the extensions created on the X6004. See
page 175.
The following example shows a configuration with three outbound line groups. ITSP
represents a SIP trunk to your VoIP service provider. PSTN represents a link to your local
traditional telephone service provider and TrustedPeer is a connection to your branch
office. Incoming calls from ITSP and from PSTN are allowed to only reach extensions of
your sales team (AG1). Calls coming in from TrustedPeer are allowed to reach the
extensions of both the sales (AG1) and research (AG2) departments. This configuration is
accomplished by removing the association to AG2 from the ITSP and PSTN outbound
line groups.
