6.10 Dial Number Detection and Digit Map

A digit map consists of a set of digit strings, called rules, which describe the dialing plan of the device.
During the process of collecting DTMF digits, the device matches the receiving digit string with the rules
in the digit map. The receiving process is completed when a match situation is encountered. A well
defined digit map helps to speed up the call setup.
