  • initiating a conversion process that involves a change from a first communications platform to a second communications platform;

    initiating a conversion script to provide a dial plan corresponding to the second communications platform;

    receiving a plurality of sequences of digits;

    generating, by a processor, one or more patterns from the sequences of digits, the patterns used to collect digits in the second communications platform and generated by;

    evaluating, by the processor, a first digit of two or more sequences of digits;

    designating, by the processor, the first digit as a significant digit of a pattern; and

    including, by the processor, one or more wildcard digits into the pattern to summarize the two or more sequences of digits, the pattern allowing for selection of call destination information for a string of dialed digits that match the pattern; and
