DigitMap Setting
Digitmaps are templates that match different sequences of digits that users dial as part of their interaction
with their phone system. After the user dials, when there is a match between the digits dialed and the
digitmap, the MTA device sends the digits to the server to initiate the call. If there is no match, the system
waits for the user to enter more digits or press the send key to indicate dialing is complete.
Load the SIP device with the digitmap pattern which corresponds to the dial plan selected by the service
operator. The digitmap is expressed in a format derived from the UNIX system command, “egrep.” You must
build the digit map based on the dialing plan which you wish to support.
