This menu is accessed from the System page by selecting Update Trunk Configurations.

This menu is accessed from the Admin Tasks list by selecting Trunks.

If a PRI trunk with the Line Subtype of ETSI is selected in the list of installed trunks, its settings are displayed below the list of installed trunks.

IP500 PRI Channel Licenses
The IP500 PRI 1 trunk daughter card supports the use of its first 8 channels unlicensed. Use of additional channels require licenses to be added to the configuration. The maximum number of channels depends on the current Line Sub-Type setting of the PRI trunk.

ETSI PRI/BRI Trunks
In PBX System mode, all incoming call routing is done using the trunk's DID Mapping Table. The table includes a default non-editable entry that routes any calls for which there is no other match to the Operator Group.

Installed Trunks
This table displays information about the trunk cards installed in the phone system. Selecting a trunk in the list displays its trunk settings below the list.

For non-North American locales, the Line Subtype of PRI trunks is ETSI.

Card/Module
Indicates the card slot or expansion module being used for the trunk device providing the line. 1 to 4 match the slots on the front of the phone system from left to right. Expansion modules are numbered from 6 upwards.

Number of Channels
The number of channels supported by a trunk depends on the Line Type and Line Subtype. Each channels can be used for a separate external call (incoming or outgoing) and can be represented by a line appearance button.

For a PRI card (ETSI), up to 30 channels are supported. The number of channels should be set to match the number supported by the line provider.

PRI Trunk Channel Setup

Channel: For information only, not editable. Not that this indicates the maximum number of channels, not the number of licensed channels usable.

Appearance ID: Default = Auto-assigned
This number is used to uniquely identify the telephone line or channel. The number can be assigned to programmable buttons on extensions to allow the users to make and answer calls on that line or channel.

Local Number
Information only. Use to any associated number for test calls to the line.

Anonymous: Default = Off
If selected, withhold sending caller ID information on outgoing calls. For PBX Mode systems this may also be invoked or overridden by the ARS selector used to route the call.

Coverage Destination: Default = None. System Mode = Key System
This option sets where incoming calls should alert in addition to alerting on those extension that have a line appearance button programmed for the line. When the phone system is in night service mode, calls alert at the members of the Night Service group.


None
If set to None, incoming calls will only alert on user extensions with line appearance buttons that match the line's Appearance ID.


Extension
Route incoming calls to a particular extension.


Phantom Extension
IP Office Release 6.1+ supports phantom extensions. One of these can be selected as the destination for calls.


Hunt Group
Incoming calls can be routed to one of the 6 rotary hunt groups.


Calling Group
For systems with their System Mode set to PBX System, incoming calls can be routed to one of the 4 collective calling groups.


Operator Group
For systems with their System Mode set to PBX System, incoming calls are routed to the Operator Group.


Voicemail
Route incoming calls to the systems voicemail to collect messages. This requires the caller to know the mailbox number and passcode.

Unique Line Ringing: Default = 1. Software level = 6.1+.
Selects the ring pattern that should be used for calls when alerting on an extension. Calls forwarded, sent to call coverage or to a hunt group will always use the line ring pattern. Calls direct to an extension will use the line ringing pattern unless the user has Override Line Ringing set. Not used for calls presented to the user as a member of the Operator group. This feature is also not used for BST phones.

 

DID Mapping Table

This table is used to set the destination for incoming calls that include DID digits. These are routed by matching the DID and ICLID information received with the call to an entry in the table. This overrides the Coverage Destination settings of the channel on which the call was received. Calls routing by DID mapping are not affected by the phone system being put into night service.

If the system is in Key system mode and no match is found, the call is routed to the first extension in the system. If the system is in PBX mode and no match is found, the call is routed to the Operator group.

The table is applied to all channels.

DID Number
If the incoming DID of a call on the trunk matches the DID set here, it will be routed to this destination. The system supports up to 4 digits DID (additional digits after the first 4 are ignored). Leave blank if only CLI matching is required.

Incoming CLI
If the incoming caller number on the trunk matches the Incoming CLI set here, it will be routed to this destination. Leave blank if only DID matching is required.

Destination
When this field is selected, the drop down list allows selection of the destination for matching calls. The options differ depending on whether the system's System Mode is set to Key System or PBX System.
