Group Calling Line ID

Group Calling Line ID

Description

Use the Group Calling Line ID feature if you want to use a single Calling Line Identity for:-

• All Users within a given Site
• A Group of Users within a given Site (e.g. sales department, HSIPT Trunking Users)

If you assign a Calling Line Identity to a Site or Group of users, the identity will be displayed to external parties who receive calls from Users at the Site or from the Group.  It provides a similar end user experience to the traditional ISDN ‘Bearer Number’.  A Group Calling Line Identity is composed of a name and a valid public phone number (presentation number) that is authorised for use by all Users or Groups of Users within the Site.

A Group or Company Administrator can set a ‘Group Calling Line ID’, using numbers added to the Site or Company through the Add New Numbers or Number Import journey. Where the number to be used is a free text presentation number, such as a Non-Geographic number or International number, then only the CP Administrator can add this to the Site.

Function

By default, all Users on a Site (excluding HSIPT extension only Users) will display their own personal number assigned to them as part of the order journey.  When the Group Calling Line Identify feature is used, then the Users Calling Line Identity number is overridden with a number selected or entered into the configuration of this feature.  External parties see the Group Calling Line Identity, not the identity of the User. For calls between Users within the Site, each User will see the other User’s personal Calling Line Identity information, even when a Group Calling Line ID is configured.

Similar to enabling Users to present an alternative Calling Line ID, this can be applied to a Trunk to allow calls made using the Trunk Phone Number (pilot number) to present an alternative identity.

This feature allows the Group or Company Administrator to:

• Define a default Group Calling Line ID (CLID) for HSIPT Extension only Users
• Define a default Group Calling Line ID (CLID) for all Users on the Site
• Define a new Calling Group using available Company numbers only as the Group Calling Line ID (CLID)
• Add or remove Users from a Calling Group
• Add or remove a Trunk Phone Number (pilot number) from a Calling Group
• Define a default Calling Group for new Users added to the Site
• Define whether the default Site Name as well as the number should override the User’s own name for outgoing on-net calls.
• Add or remove users from a Presentation Number group, added by the CP Administrator

This feature allows the CP Administrator to:

• Define a new Calling Group using a custom, UK or International, free text number as the Group Calling Line ID (CLID)
• The options for CLID for outbound calls made from the Site can be set as follows:
• Present each individual Users DDI (default)
• Present each individual Users DDI and HSIPT Extension only Users present a default Site number
• Present a default Site number for all calls from a Site or Group
• Present a single Custom UK or International number for all calls from a Site or Group

In all cases, if the User making a call has blocked the delivery of their Calling Line ID, either for a single call or for all calls, the presentation of the Group Calling Line ID is also blocked. 

Where a Hosted Centrex User has calls diverted by the IC-Talk 3 platform to another number, the original caller’s CLI will be presented.  Calls diverted by a PBX using the Diversion Header are also permitted to present the original caller’s CLI (for PBX configuration details refer to the specific SIP Device Configuration guide).

When using SIP Trunking, Class 5 CLI can be configured from the PBX instead of using the GCLID feature. Please refer to the PBX CLI pass-through option with the ‘Trunks’ feature configuration section for more information.

Configuration

The Group or Company Administrator can configure most of the Group calling Line ID feature options through the Business Portal on the Site Feature Settings page under ‘Group Calling Line ID’.  However, only a CP Administrator can create a custom number and Calling Group, but a Company/Group Administrator can add or remove people from this Calling Group.

To configure the Group Calling Line ID navigate to:

• Sites (select Site) > Features > Management > Group Calling Line ID

As default the Employee Phone Number option is selected which means all calls from the site will present the User phone number.

Please ensure you remove the number from the Group Calling Line ID before making changes to that number’.

NOTE: to meet our 999 obligations, where Group Calling Line ID is used the following will occur:

• FROM header in the SIP messaging will contain the Group Calling Number, known as the presentation number.
• The P-Asserted (PAID), network number, will contain the Users actual number, which will have an address on the ESDB database.
