E-911 managed call routing
First Claim
1. A method of local call detection and notification for a communication device that communicates with an enterprise system via a secure digital voice connection and locally with the Public Switched telephone system (PSTN) via an analog line, comprising:
- detecting within said enterprise system a dialing sequence at said communication device for which local call routing is to be applied and in response initiating call routing through said enterprise system and sending a request message to said communication device including said dialing sequence;
receiving said request message within the communication device and in response the communication device determines availability of said analog line, and in the event said analog line is available sending a response message to said enterprise system for aborting said call routing through said enterprise system and the communication device locally dialing said sequence over said analog line; and
in the event said analog line is not available continuing said call routing through said enterprise system.

Abstract
A method and system of local call detection and notification are provided for a communication device that communicates with an enterprise system via a secure digital voice connection and locally with the Public Switched telephone system (PSTN) via an analog line. A dialing sequence at said communication device is detected within the enterprise system for which local call routing is to be applied. Call routing is then initiated through the enterprise system and a request message is sent to the communication device that includes the dialing sequence. The request message is received within the communication device, which in response determines availability of the analog line. In the event an analog line is available the communication device sends a response message to the enterprise system for aborting call routing through the enterprise system, and locally dials said the sequence over the analog line. In the event an analog line is not available call routing continues through the enterprise system.

10. In call control for an enterprise system with which a communication device communicates via a secure digital voice connection, said communication device also communicating locally with the Public Switched telephone system (PSTN) via an analog line, the improvement comprising:
-
an Originating Call Process (OCP) for generating an originating call message in response to a call causing said communication device to go off-hook and dialing a sequence of digits; a routing for determining an appropriate terminator destination route from said sequence digits in response to generation of said originating call message, and generating a further message for initiating call routing via said enterprise system; and a call control sub-state for receiving said further message and in response determining whether call routing should proceed via said analog line, sending a request message to said communication device which, in response the communication device determines availability of said analog line and in the event said analog line is available the communication device sends a response message to said enterprise system, and receiving said response message and in the event said response indicates analog line availability then aborting said call routing through said enterprise system, and in the event said response indicates unavailability of analog line then continuing said call routing through said enterprise system. - View Dependent Claims (11, 12)
