Abstract
A telephone apparatus includes: a call signal detecting unit that detects a call signal transmitted via a public telephone line; an identification information detecting unit that detects source identification information transmitted via the public telephone line; and a source identification information detection control unit that controls an operation of the identification information detecting unit. The source identification information detection control unit actuates the identification information detecting unit when the call signal detecting unit detects the call signal and a predetermined condition is satisfied, and stops or does not actuate the identification information detecting unit when the call signal detecting unit detects the call signal and the predetermined condition is not satisfied.
Claims9
A telephone apparatus comprising:
- a first call signal detecting unit that detects a signal transmitted via a public telephone line as a first call signal if the signal has a predetermined frequency and continues for a predetermined time period;
- an identification information acquiring unit that executes an acquiring operation of acquiring source identification information for the signal transmitted via the public telephone line;
- a source identification information acquisition control unit that controls the acquiring operation of the identification information acquiring unit;
- and
- a determining unit that determines whether the identification information acquiring unit has acquired the source identification information,
- wherein when the first call signal detecting unit detects the first call signal, the source identification information acquisition control unit controls the identification information acquiring unit to execute the acquiring operation for the signal transmitted via the public telephone line after the first call signal if the determining unit determines that the identification information acquiring unit has not acquired the source identification information, and does not control the identification information acquiring unit to execute the acquiring operation for the signal transmitted via the public telephone line after the first call signal if the determining unit determines that the identification information acquiring unit has acquired the source identification information.
A program product for enabling a computer of a telephone apparatus including a first call signal detecting unit that detects a signal transmitted via a public telephone line as a first call signal if the signal has a predetermined frequency and continues for a predetermined time period and an identification information acquiring unit that executes an acquiring operation of acquiring source identification information for the signal transmitted via the public telephone line, to perform predetermined operations as an identification information acquisition control device for controlling an operation of the identification information acquiring unit, the operations comprising:
- judging whether the first call signal is detected by the first call signal detecting unit;
- judging whether the identification information acquiring unit has acquired the source identification information;
- and
- when it is judged that the first call signal is detected, controlling the identification information acquiring unit to execute the acquiring operation for the signal transmitted via the public telephone line after the first call signal if it is judged that the identification information acquiring unit has not acquired the source identification information, and not controlling the identification information acquiring unit to execute the acquiring operation for the signal transmitted via the public telephone line after the first call signal if it is judged that the identification acquiring unit has not acquired the source identification information.
