System and method for dynamic telephony resource allocation between premise and hosted facilities
View Patent ↗A population of networked Application Gateway Centers or voice centers provides telephony resources. The telephony application for a call number is typically created by a user in XML (Extended Markup Language) with predefined telephony XML tags and deployed on a website. A voice center provides facility for retrieving the associated XML application from its website and processing the call accordingly. The individual voice centers are either operated at a hosted facility or at a customer's premise. Provisioning Management Servers help to allocate telephony resources among the voice centers. This is accomplished by suitably updating a voice center directory. In this way, the original capacity at a premise, predetermined by the hardware installed, can be adjusted up or down. If the premise is under capacity, it can be supplemented by that from a hosted facility. If the premise has surplus capacity, it can be reallocated for use by others outside the premise.
1. In a networked computer telephony system, a method of processing telephone calls for a subscriber, comprising: providing a first set of application gateway centers in a hosted facility and a predetermined second set of application gateway centers at a premise of the subscriber for receiving and processing telephone calls; providing a directory for routing a telephone call identified by a telephone number to an application gateway center among either the first set or the second set, the directory designating an application gateway center as a function of the telephone number, predefined routing rules and operating capacities of individual application gateway centers of the first and the second set; updating the directory at predefined time intervals on the operating capacities of the individual application gateway centers; providing a user interface for a user to update user-specified routing rules in the directory; and routing the telephone call to a application gateway center according to the directory.
2. The method as in claim 1 , wherein:
the user is a subscriber, and routing rules configurable by the subscriber include telephone calls to be preferentially processed by an application gateway center on premise from the second set and to be processed by a hosted application gateway center among the first set in the event of the operating capacity of the second set fall below a predetermined threshold.
3. The method as in claim 1 , wherein:
the user is a host operator, and routing rules configurable by the host operator include telephone calls to be processed by an application gateway center among the second set in the event of the operating capacity of the first set falls below a predetermined threshold.
4. The method as in claim 1 , wherein:
the user is a subscriber, and routing rules configurable by the subscriber include telephone calls with predefined dialed numbers that must be processed by an application gateway center on premise among the second set for security reasons.
5. The method as in claim 1 , wherein:
the user is a subscriber, and routing rules configurable by the subscriber include telephone calls to be preferentially processed by a hosted application gateway center among the first set when the telephone calls are associated with a first predefined set of telephone numbers.
6. The method as in claim 1 , wherein:
routing rules configurable by the user include routing a predetermined percentage of call traffic to application gateway centers on premise among the second set.
7. The method as in claim 1 , wherein:
routing rules configurable by the user include basing on geographical location of the call to be processed.
8. The method as in claim 1 , wherein:
routing rules configurable by the user include basing on time schedule.
9. The method as in claim 1 , wherein:
routing rules configurable by the user include basing on the carrier the call originates from.
10. The method as in claim 1 , wherein:
routing rules configurable by the user include avoidance of predefined network routes.
11. The method as in claim 1 , wherein:
the user is a subscriber, and routing rules configurable by the subscriber include routing from one premise to another premise of the subscriber.
12. The method as in claim 1 , further comprising:
providing a plurality of Extended Markup Language (XML) documents being hosted by web servers on the Internet, each of the XML documents constituting a telephony application associated with a specified call number and including telephony-specific XML tags instructing how a telephone call to the specified call number is to be processed;
providing a telephony application directory for locating the telephony application for the specified call number; and wherein:
the application gateway center the specified call is routed to retrieves the associated telephony application according to the telephony application directory.
13. The method as in claim 12 , wherein:
the telephony application for the specified call number exists in multiple versions; and
the version retrieved by a application gateway center depends on the location of the retrieving application gateway center.
14. A networked computer telephony system, comprising: a plurality of Extended Markup Language (XML) documents being hosted by web servers on the Internet, each of said XML documents constituting a telephony application associated with a specified call number and including telephony-specific XML tags instructing how a telephone call to the specified call number is to be processed; a plurality of application gateway centers distributed over a plurality of locations, each application gateway centers having a predetermined capacity to receive and process the XML documents associated with specified call numbers; a directory of application gateway centers, the directory designating an application gateway center as a function of the call number, predefined routing rules and operating capacities of individual application gateway centers of the first and the second set; and a provisioning management server responsive to the plurality of application gateway centers for updating said directory at predefined time intervals the operating capacities of the individual application gateway centers.
15. A networked computer telephony system as in claim 14 , wherein: said provisioning management server further comprises:
a user interface for a user to update user-specified routing rules in the directory.
16. A networked computer telephony system as in claim 15 , wherein:
the user is a subscriber, and routing rules configurable by the subscriber include telephone calls to be preferentially processed by an application gateway center on premise from the second set and to be processed by a hosted application gateway center among the first set in the event of the operating capacity of the second set fall below a predetermined threshold.
17. A networked computer telephony system as in claim 15 , wherein:
the user is a host operator, and routing rules configurable by the host operator include telephone calls to be processed by an application gateway center among the second set in the event of the operating capacity of the first set falls below a predetermined threshold.
18. A networked computer telephony system as in claim 15 , wherein:
the user is a subscriber, and routing rules configurable by the subscriber include telephone calls with predefined dialed numbers that must be processed by an application gateway center on premise among the second set for security reasons.
19. A networked computer telephony system as in claim 15 , wherein:
the user is a subscriber, and routing rules configurable by the subscriber include telephone calls to be preferentially processed by a hosted application gateway center among the first set when the telephone calls are associated with a first predefined set of telephone numbers.
20. A networked computer telephony system as in claim 15 , wherein:
routing rules configurable by the user include routing a predetermined percentage of call traffic to application gateway centers on premise among the second set.
21. A networked computer telephony system as in claim 15 , wherein:
routing rules configurable by the user include routing a predetermined percentage of call traffic to application gateway centers on premise among the second set.
