Users, Departments, Contacts and Meet Me Conferences can be assigned to different Companies so that
in a multi-tenancy system Users are unaware of the usage of the system by other businesses. An Auto

Trunks
Trunks are the method used for outgoing or incoming communication with the system whether via ISDN,
SIP, or H.323. Each Trunk port available on the system can be configured individually. Please refer to the
Working with Trunks section from page 159 for further details.
Trunk Groups
A Trunk group allows the grouping together of multiple Trunks for delivery of calls. This is very useful in
geographically organising the flow of calls, and can also be used to differentiate levels of service, by
keeping spare capacity for high priority calls. Please refer to the Working with Trunks section from page
161 for further details.
DDI Call Plans
Direct Dial In Call Plans determine how incoming ISDN calls will be routed. Please refer to the Working
with DDI Plans section from page 169 for further details.
LCR Plans
LCR Plans apply to all calls that will be routed to a trunk via a gateway. It allows the best selection of a
trunk and selection of service providers, based upon the number dialled and time of day. It can also be
used to control the geographic exit point from the network, eg all calls to London numbers would exit via
a London trunk module, but calls to Edinburgh would exit via the Edinburgh trunk module. If a trunk
should be busy or fail then alternate translations and trunks would be used. Please refer to the Working
with LCR Plans section from page 175 for further details.
Voicemail Ports
A Voicemail Port determines the facilities provided by a Call Server’s voicemail service. Where more than
one Call Server is active on a system Voicemail Ports allow different capabilities to be assigned to each
Call Server providing a voicemail service. Please refer to the Working with Voicemail section from page
188 for further details
Music Channels

from an internally stored WAV file or via an external source. Please refer to the Configuring Music
Channels section from page 177 for further details.
Events

company information etc. A Relay Input port or a Dial Plan entry can activate an Event. Please refer to
the Using Events section from page 181 for further details.
