AT&T IP Flexible Reach Customer Portal: Enterprise Administrator Support

About Group Trunk Groups

 

Trunking is a concept that enables a communications system to provide 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.

 

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.

 

As part of managing group trunk groups in your role as an Enterprise Administrator for the IP Flexible Reach Customer Portal, you can:

  • Edit group trunk group profiles.
  • Edit the associated trunk call routing schemes.

 

Note: You must have the appropriate permissions to view and edit trunk call routing schemes.
