Patent ID: 7242760

Claim:
A method for automatically detecting when an agent is available, comprising: connecting a telephony server between a user station and a call center not having call back capabilities via a telephone switching network, the call center in communication with at least one agent station; connecting a browser server to the telephony server and the user station and the agent station; the telephony server receiving a request from the user station via the browser server for a call-back from an agent; the telephony server configured to encode information received from the web server into a dual tone multi frequency (DTMF) string, the telephony server also calling the call center using said DTMF string; the call center connecting the call to the agent station; entering an agent ID, by an agent at an agent station when the agent answers the call from the telephony server, the agent ID entered yielding DTMF tones encoding the agent ID corresponding to the agent; detecting, by a telephony server, the DTMF tones resulted from the agent ID entered by the agent to detect that the agent is available; and the telephony server calling back the user station and bridging a call back between the user station and the available agent.
