Remote line access for a multi-line residential telephone
Abstract:
A method for remote accessing a multi-line residential telephone system. Using a first remote telephone, a calling party dials a telephone number associated with a first telephone line of the multi-line residential telephone system. After a predetermined number of unanswered rings at the first telephone line of the multi-line telephone system, the multi-line telephone system prompts the calling party to input a code. After a successful verification of the code, the multi-line telephone system connects the first remote telephone with a second telephone line of the multi-line telephone system so that the calling party receives a dial tone over the second telephone line. The calling party then dials a terminating telephone number associated with a second remote telephone to establish communication with a called party of the second remote telephone.
