ABSTRACT:
An IP-based node in communication with IP-based gateway devices is configured for executing circuit selection for a prescribed trunk group having multiple sets of connected trunk groups, the multiple sets of connected trunk groups managed by the respective IP-based gateway devices. The prescribed trunk group is configured for connecting with a two-way trunk group of a switch, for example a PSTN-based switch, having substantially more circuits than any one of the multiple sets of connected trunk groups for the IP-based gateway devices. The IP-based node executes circuit selection at least based on a first message, received from one of the IP-based gateway devices via an IP connection and specifying circuit availability for at least a portion of the corresponding set of connected trunk groups. The IP-based node outputs to the one IP-based gateway device an IP-based selection message specifying a selected circuit within the corresponding set of connected trunk groups, enabling the one IP-based gateway device to select the selected circuit for communication with the switch based on the IP-based selection message.
