ABSTRACT:
A system and method for automatically examining and correcting telephone numbers to increase the likelihood of establishing communication between a local device, such as a fax card or modem, and a remote device. Proposed telephone numbers are identified and compared against user specified comparison templates to determine if the proposed numbers are proper for establishing communication. If they are, they are approved for dialing. However, if they are not, the proposed numbers are modified according to user specified rules which form output templates. The modified number is then approved for dialing. The system is beneficially implemented using a computer which stores a set of comparison templates and a set of associated output templates in memory. The computer compares a specified number, corrects it as required, and applies it to the local device for dialing.
