Cordless telephone active-call enabled intercom
View Patent ↗A method of using an intercom on a cordless telephone during an active call. The active call is put on hold while the intercom is in use. Once the call is re-activated, the intercom is shut off. This system may be designed for a cordless telephone with one handset or a plurality of handsets.
1. A cordless telephone system comprising:
a base station including first control circuitry for controlling operations at said base station; and
at least two cordless telephone handsets for communicating with said base station, each including second control circuitry for controlling operations at said cordless telephone handset;
said first and second control circuitry operating in response to initiation of an intercom communication at a first of said cordless telephone handsets to place an active call at the first cordless telephone handset on hold during said intercom communication, the intercom communication permitting voice communication between at least two of said cordless telephone handsets.
2. The system as in claim 1 , wherein said first control circuitry causes said active call to be placed on hold when said intercom communication is initiated during said active call and initiates said intercom communication between said cordless telephone handsets.
3. The system as in claim 2 , wherein said first control circuitry causes said active call to be re-engaged when one of said cordless telephone handsets terminates said intercom communications.
4. A cordless telephone system comprising:
a base station including first control circuitry for controlling operations at said base station; and
at least first and second cordless telephone handsets for communicating with said base station including second and third control circuitry for controlling operations at said first and second cordless telephone handsets respectively;
said first, second and third control circuitry operating in response to initiation of an intercom communication at one of said first and second cordless telephone handsets to place an active call on hold during said intercom communication, the intercom communication permitting voice communication between at least two of said cordless telephone handsets.
5. The system as in claim 4 , wherein said first control circuitry causes said active call to be placed on hold when said intercom communication is initiated during said active call and initiates said intercom communication between at least two of said cordless telephone handsets.
6. The system as in claim 5 , wherein said first control circuitry causes said active call to be re-engaged when at least one of said cordless telephone handsets terminates said intercom communication.
7. A cordless telephone system comprising:
a base station including first control circuitry for controlling operations at said base station and separate intercom buttons for each of a plurality of cordless telephone handsets, said plurality of cordless telephone handsets comprising at least first and second cordless telephone handsets for communicating with said base station and including second and third control circuitry for controlling operations at said first and second cordless telephone handsets, respectively, and a separate intercom button for said base station and each other of said cordless telephone handsets;
said first, second, and third control circuitry operating in response to initiation of an intercom communication at one of said first and second cordless telephone handsets to place an active call on hold during said intercom communication, the intercom communication permitting voice communication between at least two of said cordless telephone handsets.
8. The system as in claim 7 , wherein said first control circuitry causes said active call to be placed on hold when said intercom communication is initiated during said active call and initiates said intercom communication between at least two of said cordless telephone handsets.
9. The system as in claim 8 , wherein said first control circuitry causes said active call to be re-engaged when one of said cordless telephone handsets terminates said intercom communications.
