US Patent 7455304 Telephone quick dialing and re-dialing

A telephone is equipped to enable a user to enter a dialing prefix, an append indicator, and a dialing request to quickly place a call to a callee from a location where calling the callee requires the dialing prefix. In response, the telephone places the call to the callee using the dialing prefix and a last placed call number. In an alternate embodiment, a previous dialed number may be used instead. In yet other embodiments, the telephone detects for a dialing error, using voice recognition technology, and either re-places the call or facilitates re-placement of the call in a corrected manner. In one embodiment, the telephone is a wireless mobile phone; in another, the telephone is a wired or cordless telephone handset.
