Memory call origination system for automatically originating a call to a calling party

DETAILED DESCRIPTION It is therefore an object of the present invention to provide a memory call origination system capable of recording a telephone number of the calling party included in a transmitted call signal.
Another object of the present invention is to provide a memory call origination system capable of extracting the telephone number of the calling party from the call signal transmitted over the control channel.
Yet another object of the present invention is to provide a memory call origination system capable recording a telephone number of the other party via a radio channel.
It is further object of the present invention to provide a memory call origination system capable of recalling a stored telephone number to originate a call to the other party who sent the recorded speech message.
The telephone answering system according to the present invention is capable of extracting and storing the telephone number of a calling party and, thereafter, automatically originating a call to that party by recalling its number from the memory.
However, unlike the systems of the prior art, the system of the present invention extracts the calling number from a digital signal transmitted over the common control channel.
This provides better reliability and accuracy.
The extracted number is recorded digitally in a RAM and can be used to originate a call to the calling party.
When the calling party calls the number where the system is installed, the system receives a digital channel signal including an ID number of the calling party via a common control channel.
The system extracts and records the ID number of the calling station.
It then transmits a recorded message inviting the caller to leave a speech message.
If a speech message is received from the calling party via a communication channel, the communication device records the received speech signal.
The user may then instruct the system to read the recorded ID number and commence automatic calling of the recorded ID number.
More definitely, the communication device according to the present invention, receives a channel signal including a first identification number of the called station and a second identification number of the calling station over the control channel, and a speech signal over the speech channel
