AT&T IP Flexible Reach Customer Portal: Group Administrator Support
About Group Trunk Groups
Trunking is a concept that describes how a communications system provides network access to many users by sharing a set of lines or frequencies, instead of providing the lines or frequencies individually. A trunk is a single transmission channel between two points, one point being the switching center and one the node.
The term trunk refers to the structure of the system, which can be compared to a tree with one trunk and many branches.
A group trunk group is the path that a call takes between AT&T IP Flexible Reach and your organization's PBX (private branch exchange), and ultimately the user.
The group trunk group has a set maximum number of calls, incoming and outgoing, that it can handle simultaneously.
A trunk call routing scheme enables you to:
- Bundle one or more group trunk groups and assign the bundled group trunk group an identity.
- Place rules on that identity that select which one of the bundled group trunk groups receives an incoming call.
When you create a group, IP Flexible Reach creates a single group trunk group and adds it to a trunk call routing scheme created for that group. You can then add other group trunk groups to that trunk call routing scheme.
As part of managing group trunk groups in your role as a Group Administrator for the IP Flexible Reach Customer Portal, you can edit your group trunk group profile.
