Abstract

A system and method are disclosed herein for providing a unidirectional outage bypass for incoming communications via a hosted Voice-over Internet Protocol (VoIP) private branch exchange (PBX) system to a session initiation protocol (SIP) device. An outage monitoring system is in communication with both the unidirectional bypass system and one or more bypass enablers that act at the direction of the unidirectional bypass system. The outage monitoring system detects outages and overloads, as well as, network failures between network components, the VoIP PBX, Client Devices and the public switched telephone network (PSTN). The unidirectional bypass system, in response to detection of an outage, determines error-handling procedures for the unidirectional bypass based on bypass configuration data. The bypass enablers forward incoming communications between the PSTN and a bypass destination following a bypass route in accordance the error-handling procedures, by bypassing components that are currently experiencing failures or overloads.

Claims

1. A system for providing a unidirectional outage bypass for a hosted Voice-over Internet Protocol (VoIP) private branch exchange (PBX) system comprising:

a client device or a group of client devices in a network in communication with the VoIP PBX and with an outage monitoring system, wherein;

the outage monitoring system in communication with a bypass configuration system and in communication with one or more bypass enablers that act at the direction of the bypass configuration system wherein;

the outage monitoring system monitors the network components, the VoIP PBX, as well as, network connections between the VoIP PBX, client devices and the public switched telephone network (PSTN) for outages, failures and overload conditions;

the bypass configuration system, in response to an outage detection by the outage monitoring system, directs the bypass enablers to route incoming communications between the PSTN and the client devices while bypassing the network components and/or VoIP PBX components that are currently experiencing failures or overloads; and

wherein;

the bypass configuration system directs the routing of the incoming communications via the bypass enablers based on a set of bypass configuration data.

2. The system according to claim 1, wherein a predetermined set of rules for responding to outages and overload conditions in the VoIP PBX system is included in the bypass configuration data.

3. The system according to claim 2, wherein the bypass configuration system directs the bypass enablers to route the incoming communications to the client devices based on the predetermined set of rules.

4. The system according to claim 3, wherein the edge server provides Internet protocol (IP) addressing information associated with a specific client device on the network to allow the incoming communication to bypass the VoIP PBX such that the incoming communication can be routed directly to the specific client device.

5. The system according to claim 2, for configuring the edge server based on the predetermined set of rules for forwarding the incoming communications to an alternate number.

6. The system according to claim 2, wherein the bypass configuration system forwards an incoming communication to a voice mail system based on the predetermined set of rules.

7. The system according to claim 2, wherein the bypass configuration system routes an incoming communication to a caller notification system for playing a pre-configured audio message to a caller.

8. The system according to claim 2, wherein the bypass configuration system routes an incoming communication to a caller notification system for playing a pre-configurable audio message to a caller in response an incoming communication from a specific phone number.

9. A method for providing a unidirectional outage bypass for a hosted Voice-over Internet Protocol (VoIP) private branch exchange (PBX) system comprising:

providing a client device or group of client devices on a VoIP PBX network;

monitoring a VoIP PBX network with an outage monitoring system in communication with a bypass configuration system and in communication with one or more bypass enablers that act at the direction of the bypass configuration system wherein;

monitoring the hosted VoIP PBX system for outages and overload conditions, as well as for network failures between the VoIP PBX and a public switched telephone network (PSTN) and/or for network failures between the VoIP PBX and a client device or a group of client devices;

directing the bypass configuration system, in the event of a detected failure by the outage monitoring system, to route incoming communications between the PSTN and the client devices via the bypass enablers; and

using the bypass enablers to direct the routing of the incoming communications based on a set of bypass configuration data.

10. The method according to claim 9, for including a predetermined set of rules for responding to outages and overload conditions in the VoIP PBX system in the bypass configuration data.

11. The method according to claim 10, for directing the bypass enablers to route the incoming communications directly to the client devices based on the predetermined set of rules.

12. The method according to claim 10, for using an edge server provides Internet protocol (IP) addressing information associated with a specific client device on the network to allow the incoming communication to bypass the VoIP PBX such that the incoming communication can be routed directly to the specific client device.

13. The method according to claim 10, for routing incoming communications to a client device based on the predetermined set of rules.

14. The method according to claim 13, for routing incoming communications to an alternative phone number based on the predetermined set of rules.

15. The method according to claim 10, for routing incoming communications to a caller notification system for playing a pre-configured audio message based on the predetermined set of rules.

16. The method according to claim 10, for routing incoming communications to a caller notification system for playing a pre-configured audio message based on the phone number of the incoming call.

17. A system of providing a unidirectional outage bypass for a hosted Voice-over Internet Protocol (VoIP) private branch exchange (PBX) system comprising:

an outage monitoring system configured to detect outages and overload conditions of VoIP network components including the VoIP PBX, as well as, network failures between the VoIP PBX, a public switched telephone network (PSTN) and one or more client devices; and

a bypass configuration system in communication with an edge server, the outage monitoring system and one or more bypass enablers for routing incoming communications based on a set of bypass configuration data.

18. The system according claim 17, wherein a predetermined set of rules for responding to outages and overload conditions in the VoIP PBX system and network components are included in the bypass configuration data.

19. The system according claim 18, wherein the predetermined set of rules can direct the unidirectional outage bypass system to play a configurable audio message to callers attempting an incoming communication.

20. The system according claim 17, wherein the unidirectional outage bypass system, in response to a network outage, directs incoming communications from the public switched telephone network (PSTN) to a client device by bypassing the VoIP PBX.

21. The system according to claim 17, wherein outages, overloads, and failures of the hosted VoIP PBX include any interruption in network, hardware, or software services.

22. The system according to claim 21, wherein failures of the hosted VoIP PBX hardware and software services includes an inability to complete incoming and/or outgoing communications through the hosted VoIP PBX.
