Method and apparatus for changing a telephone number after entry

1. A computerized system for assisting a user with placing a telephonic call, comprising a user interface, computerized processing, and computerized storage for:

a user specifying an originally-specified telephone number to place an intended telephonic call, which telephone number, as originally-specified, for at least one particular reason, cannot be used to successfully complete the intended telephonic call;

after specifying the originally-specified telephone number, later specifying later-specified telephone number elements, including the possible deleting, ignoring or changing of part of said originally-specified telephone number and/or related dialing elements; and

causing the telephonic call to be successfully signaled using said originally-specified telephone number in combination with said later-specified telephone number elements, without the user having to re-specify said originally-specified telephone number; wherein:

said originally-specified telephone number is stored in a redial memory, for purpose of said deleting, ignoring or changing and signaling, until the user initiates a brand new dialing effort to place a new telephonic call.

2. The system of claim 1 , wherein:

said originally-specified telephone number comprises a telephone number entered without an area code;

said at least one particular reason comprising that the telephonic call cannot be successfully completed without specifying said area code; and

said later-specified telephone number elements comprising said area code.

3. The system of claim 1 , wherein:

said originally-specified telephone number comprises a telephone number entered without a dialing prefix;

said at least one particular reason comprising that the telephonic call cannot be successfully completed without specifying said dialing prefix; and

said later-specified telephone number elements comprising said dialing prefix.

4. The system of claim 1 , wherein:

said originally-specified telephone number comprises a telephone number for which at least one telephone number digit is not correct;

said at least one particular reason comprising that said at least one telephone number digit is not correct; and

said later-specified telephone number elements comprising at least one correction to said at least one telephone number digit which is not correct.

5. The system of claim 1 , wherein:

said originally-specified telephone number comprises a telephone number which could have been used to successfully complete the intended telephonic call under a superseded dialing plan;

said at least one particular reason comprising that the superseded dialing plan has been superseded by a superseding dialing plan; and

said later-specified telephone number elements comprising telephone number elements required, in combination with said originally-specified telephone number, to successfully complete the intended telephonic call in accordance with the superseding dialing plan.

6. The system of claim 1 , wherein:

said originally-specified telephone number comprises a telephone number entered without an area code;

said at least one particular reason comprising that it is intentionally desired to have the user dial all calls so as to include an area code; and

said later-specified telephone number elements comprising said area code.

7. The system of claim 1 , further comprising determining that said originally-specified telephone number cannot be used to successfully complete the intended telephonic call.

8. The system of claim 7 , further comprising determining said at least one particular reason, and providing a prompt advising the user to specify said later-specified telephone number elements.

9. The system of claim 1 , further comprising determining said at least one particular reason, and providing a prompt advising the user to specify said later-specified telephone number elements.

10. The system of claim 1 , further comprising:

storing a number which has been successfully dialed in a reference database for assisting a caller in successfully completing future calls; and

causing a future telephonic call to be successfully signaled using one or more telephone number elements from said stored number.

11. The system of claim 1 , further comprising determining that the user has initiated a brand new dialing effort.

12. The system of claim 11 , further comprising determining that the user has initiated a brand new dialing effort based on the number of digits changed by said later-specified telephone number elements, and/or whether said changes are to the area code or to another part of the telephone number.

13. The system of claim 1 , further comprising: as a default if some other action is not timely taken, causing said telephonic call to be successfully signaled using said originally-specified telephone number in combination with said later-specified telephone number elements.

14. The system of claim 1 , further comprising: after the user specifying the originally-specified telephone number, a computerized system later automatically specifying later-specified telephone number elements.

15. The system of claim 14 , said telephone number elements later specified by the computerized system comprising the possible deleting, ignoring or changing of part of said originally-specified telephone number and/or related dialing elements.

16. The system of claim 1 , further comprising: after the user specifying the originally-specified telephone number, the user later specifying later-specified telephone number elements.

17. The system of claim 16 , said telephone number elements later specified by the user comprising the possible deleting, ignoring or changing of part of said originally-specified telephone number and/or related dialing elements.
