Business Trunking is a service that provides a new framework and introduces the concept of a "Trunk Group" used to serve PBX-type customer premises equipment. This framework provides better support for intelligent customer premises equipment (CPE) such as PBXs, while still allowing Broadcore services to be offered to CPE users. The trunk group allows for licensing a configurable number of simultaneous calls that can be handled by a selected group of users, referred to as trunk users.
The CPE can pull some services from Broadcore, such as:
- Account/Authorization Codes
- Calling Plans
- Auto Attendant
- Hunt Groups
- Call Centers
- Series Completion
The CPE can pull network services from Broadcore, such as:
- Abbreviated dialing
- Voice VPN
- Far-End Hop-Off
Trunk group name - This is name for the trunk group, which is unique within the group.
Call capacity - This is the maximum number of concurrent calls that can be processed by trunk users in a trunk group. Call capacity can also be configured for incoming and outgoing calls. When the maximum number of calls is reached for a trunk group, or for incoming and outgoing capacities, the call is released with a BUSY release cause for a blocked termination and a FORBIDDEN release for a blocked origination.
List of trunk users - These users are mapped to the CPE, using the trunk as an access method. All calls processed for these users are accounted for by the trunk group call capacity.
Trunking device - This device is the access device that represents the CPE (and which holds the IP address and port information). There can only be one trunking device per trunk group, so all trunk users make use of that trunking device. Any group device can be used for the trunk.
The enhancement, Trunk Group Hosted User Capacity Sharing, allows regular Broadcore users to be included in a Trunk Group for call capacity management.
Business Trunking, adds three key functionalities to the Trunk Group service:
- Allows burst call capacity for Trunk Groups.
- Allows actions to be assigned to the Trunk Group on device unreachable and call capacity exceeded conditions.
- Allows DIDs and main numbers for basic calling and enhanced calling with Call Accounting Reporting.
The trunk group is added as a virtual user in the system and the web is similar to other virtual users (Auto Attendant, Call Center, and so on). Items specific to the trunk group are the device associated with it, the call capacity for the trunk group and the authentication password. When modifying the trunk group, the same attributes are shown in addition to a list of group users using the trunk group. If any users are currently using the trunk group, the device selected may not be changed.
The trunk group is associated to the user as if it were a device in the profile page of the user. The group administrator selects the trunk group and fills in the line port that is displayed based on the rules of the device associated with the trunk group.
