Abstract

A telephone system with a caller ID logging feature includes a plurality of telephone stations which share a plurality of telephone lines connected to the telephone system. Each one of the plural telephone lines is associated with one or more of the telephone stations. A control processor (CPU) monitors the incoming calls on the telephone lines connected to the telephone system, and also receives caller ID information from the Central Office of the telephone service provider. For unanswered incoming calls and answered calls which are to be stored, the CPU stores the associated caller ID information in a memory as a caller ID record including data indicating the telephone lines on which the incoming call was received. The stored caller ID records for each telephone line are accessible from telephone stations that are associated with that telephone line. Therefore, only one record is required which all users may access, thereby increasing the efficiency of the memory over prior art systems. The memory includes a minimum capacity per line so that a minimum number of records are allocated for each telephone line.

Claims

1. A method of storing incoming caller ID information records in a memory of a business telephone system connected to a plurality of telephone lines and including a plurality of telephone stations, comprising the steps of:

(a) associating one of said plurality of telephone lines with one of said plurality of telephone stations;

(b) monitoring all incoming calls on the plurality of telephone lines with a processor;

(c) receiving incoming caller ID information from a Central Office for each incoming call on the plurality of telephone lines;

(d) storing in the memory the received caller ID information for each unanswered call as a caller ID record so as to associate the stored caller ID information with the telephone line on which the call was received; and

(e) allocating a minimum number of records in the memory for each of said plural telephone lines.

3. The method of claim 1, wherein said step of storing further comprises:

(f) temporarily storing the caller ID information in the processor of the telephone business system;

(g) determining that an incoming call is unanswered; and

(h) storing the caller ID information for the incoming call determined to be unanswered in step (g).

4. The method of claim 3, wherein said step (h) further comprises:

(i) checking the memory for a free record in which a new caller ID record may be stored;

(j) storing the caller ID information for the incoming call in the free record if a free record is found in said step (i);

(k) determining an oldest caller ID record for all telephone lines having more than a minimum amount of caller ID records stored in the memory, if a free record is not found in said step (i);

(l) erasing the oldest caller ID record found in said step (k); and

(m) storing the caller ID information for the incoming call in the erased caller ID record of said step (l).

5. The method of claim 1, further comprising the steps of determining if answered calls are to be stored, and storing the caller ID information for an incoming call when the incoming call is answered if it is determined that answered calls are to be stored.

6. The method of claim 1, further comprising the step of accessing, from the one of plural telephone stations, a stored caller ID record in the memory associated with the one of the plural telephone lines.

7. The method of claim 6, wherein said step of accessing the stored caller ID record comprises:

selecting one stored caller ID record from among a plurality of caller ID records stored in the memory and that were received on the one of the plural telephone lines that is associated with the one of the plural telephone stations; and

transmitting the one of the plural of stored caller ID records to the one of the plural telephone stations.

8. The method of claim 7, further comprising the step of transmitting a next one of the plural stored of caller ID records to the one of the plural telephone stations.

9. The method of claim 7, further comprising the step of sorting the plural stored caller ID records for transmission to the one of the plural telephone stations in reverse chronological order;

and

said step of transmitting a selected one of the plural stored caller ID records comprising transmitting a newest in time of the plural stored caller ID records to the one of the plural telephone stations.

10. The method of claim 7, further comprising the step of transmitting one of a next newest and a next oldest of the plural stored caller ID records to the one of the plural telephone stations.

11. The method of claim 1, wherein said step of allocating further comprises the steps of allocating a first minimum number of records in the memory for a first of said plural telephone lines and a second minimum number of records in the memory for a second of said plural telephone lines, wherein said first minimum number and said second minimum number are based on a number of calls normally received on each of the first and second of said plural telephone lines.

2. A method of storing incoming caller ID information records in a memory of a business telephone system connected to a plurality of telephone lines and including a plurality of telephone stations, comprising the steps of:

(a) associating one of said plurality of telephone lines with one of said plurality of telephone stations;

(b) monitoring all incoming calls on the plurality of telephone lines with a processor;

(c) receiving incoming caller ID information from a Central Office for each incoming call on the plurality of telephone lines;

(d) storing in the memory the received caller ID information for each unanswered call as a caller ID record so as to associate the stored caller ID information with the telephone line on which the call was received; and

(e) selecting selected ones of said plurality of telephone lines to be monitored for incoming calls, and wherein said step of monitoring further comprises monitoring only said selected ones of said plural of telephone lines and said step of storing further comprises storing the caller ID information only for the selected ones of said plural telephone lines.

12. A device for logging incoming caller ID information records for unanswered incoming calls on a telephone system having a plurality of telephone stations and connected to a plurality of telephone lines, said device comprising:

a processor having a dynamic memory for storing incoming caller ID information as a caller ID information record so that each said stored caller ID information record is associated in the memory with the one of the telephone lines on which it was received, and wherein said memory allocates a minimum number of record spaces for each of said plural telephone lines; and

each of said plural telephone stations connected to said processor comprising means for accessing selected ones of the stored caller ID records in said memory and a display for displaying a currently selected one of the stored caller ID records.

13. The telephone system of claim 12, wherein each of the plural telephone stations is associated with a selected one of the plural telephone lines for receiving at the said telephone station incoming telephone calls on the selected one telephone line, and wherein said means for accessing comprises means for accessing on each telephone set only ones of the stored caller ID records that are associated with incoming telephone calls on the selected one telephone line associated with the each telephone station.

15. The telephone system of claim 12, wherein said processor is operatively connected for temporarily storing incoming caller ID information for each incoming call, for determining whether the incoming caller ID information should be stored in the memory as a caller ID information record, and for storing the incoming caller ID information in the memory as a caller ID information record associated with the telephone line in which the incoming telephone call identified by the incoming caller ID information record was received.

16. The telephone system of claim 12, wherein said processor is operatively connected to said plurality of telephone lines for storing incoming caller ID information as a caller ID record by searching the memory for a free record, and
