Hierarchically organizing logical trunk groups in a packet-based network

Described are methods and apparatus, including computer program products, for defining logical trunk groups in a packet-based network. A plurality of logical trunk groups are defined for a first media gateway in communication with a packet-based network. Each of the plurality of logical trunk groups is associated with one or more media gateways in communication over the packet-based network with the first media gateway. Data associated with a call that is received or transmitted by the media gateway is associated with a first logical trunk group of the plurality of logical trunk groups. Calls and call traffic can be monitored and managed by employing control features associated with logical trunk groups, including managing by using resource parameters. Some embodiments feature hierarchical configurations of logical trunk groups to implement monitoring and management features.
