Configuration of shared trunk groups in an IP telephony network
View Patent ↗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.
1. A method for configuring a communication network, the method comprising:
registering a first PBX (Public Branch Exchange) as part of a first enterprise communication system operated by a first enterprise;
registering a second PBX as part of a second enterprise communication system operated by a second enterprise;
selecting the first and second enterprises based upon a first time zone of the first enterprise communication system and a second time zone of the second enterprise communication system;
assigning a first resource pool for shared use by the first plurality of digital PBXs and the second plurality of PBXs, wherein the first resource pool includes communication resources associated with the second PBX for shared use between the first and second enterprise communication systems for providing communication services to the first plurality of digital PBXs and the second plurality of digital PBXs;
specifying a first portion of the communication resources that are reserved for use by the first PBX;
assigning a second portion of the communication resources for dedicated use by the second enterprise communication system, wherein the first portion of the communication resources provides a number of communication channels above a maximum number of channels allowed for use by the first enterprise communication system;
enforcing the maximum number of channels allowed for use by the first enterprise by limiting a number of shared channels in the shared communication resources that are available to the first enterprise communication system; and
permitting an emergency communication at the first enterprise using a number of channels above the maximum number of channels allowed for use by the first enterprise communication system.
2. The method of claim 1 , further comprising:
specifying a first maximum number of communication resources that may be simultaneously used by the first and second enterprise communication systems.
3. The method of claim 2 , wherein the number of resources in the first portion of the communication resources is specified as a percentage of the first maximum number of communication resources.
4. The method of claim 1 , further comprising:
reserving a subset of the first communication resources to be used for expanding ongoing communications by the first enterprise communication system.
5. The method of claim 1 , wherein the first enterprise communication system is associated with a first internet domain and the second enterprise communication system is associated with a second internet domain.
6. The method of claim 1 , further comprising:
specifying one or more directory numbers associated with the first PBX.
7. The method of claim 1 , further comprising:
reassigning the first PBX to a second communication resource group in response to detecting insufficient capacity in a first communication resource group.
8. A system, comprising:
a processor; and
a memory coupled to the processor, the memory including computer-readable instructions that, upon execution by the processor, cause the system to:
register a first PBX (Public Branch Exchange) as part of a first enterprise communication system operated by a first enterprise;
register a second PBX as part of a second enterprise communication system operated by a second enterprise;
select the first and second enterprises based upon a first time zone of the first enterprise communication system and a second time zone of the second enterprise communication system;
assign a first resource pool for shared use by the first plurality of digital PBXs and the second plurality of PBXs, wherein the first resource pool includes communication resources associated with the second PBX for shared use between the first and second enterprise communication systems for providing communication services to the first plurality of digital PBXs and the second plurality of digital PBXs;
specify a first portion of the communication resources that are reserved for use by the first PBX;
assign a second portion of the communication resources for dedicated use by the second enterprise communication system, wherein the first portion of the communication resources includes a number of communication channels above a maximum number of channels allowed for use by the first enterprise communication system;
enforce the maximum number of channels allowed for use by the first enterprise by limiting a number of shared channels in the shared communication resources that are available to the first enterprise communication system; and
permit an emergency communication at the first enterprise using a number of channels above the maximum number of channels allowed for use by the first enterprise communication system.
9. The system of claim 8 , wherein the computer-readable instructions, upon execution by the processor, cause the system to:
specify a first maximum number of communication resources that may be simultaneously used by the first and second enterprise communication systems.
10. The system of claim 9 , wherein the number of resources in the first portion of the communication resources is specified as a percentage of the first maximum number of communication resources.
11. The system of claim 8 , wherein the computer-readable instructions, upon execution by the processor, cause the system to:
reserve a subset of the first communication resources to be used for expanding ongoing communications by the first enterprise communication system.
12. The system of claim 8 , wherein the first enterprise communication system is associated with a first internet domain and the second enterprise communication system is associated with a second internet domain.
13. The system of claim 8 , wherein the computer-readable instructions, upon execution by the processor, cause the system to:
specify one or more directory numbers associated with the first PBX.
14. The system of claim 8 , wherein computer-readable instructions, upon execution by the processor, cause the system to:
reassign the first PBX to a second communication resource group in response to detecting insufficient capacity in a first communication resource group.
