A method and system of local call detection and notification are provided fo r a communication device that communicates with an enterprise system via a secur e 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 includ es 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.
