Abstract: System and methods are disclosed for configuring the sharing of resource pools and individual resources in the resource groups among enterprise communication systems. In certain embodiments, the resource pools are trunk groups and the individual resources that comprise the trunk groups are communication resources. Digital PBXs components associated with different enterprise communication systems are registered and assigned shared use of a trunk group. Communication services are provided to the digital PBXs using the channels of the shared trunk group. Each enterprise may reserve channels within the trunk group for exclusive use by the enterprise, while sharing use of other channels in the trunk group. Each enterprise can be guaranteed a minimum calling capacity while providing improved resource utilization due to fewer idle communication channels.
