Version 5.8 447 October 2009
SIP User's Manual 8. Auxiliary Configuration Files
The Dial Plan must be prepared in a textual ini file with the following syntax:
îš„ Every line in the file defines a known dialing prefix and the number of digits expected
to follow that prefix. The prefix must be separated from the number of additional digits
by a comma (',').
îš„ Empty lines are ignored.
îš„ Lines beginning with a semicolon (';') are ignored.
îš„ Multiple dial plans may be specified in one file; a name in square brackets on a
separate line indicates the beginning of a new dial plan. Up to eight dial plans can be
defined.
îš„ Asterisks ('*') and number-signs ('#') can be specified as part of the prefix.
îš„ Numeric ranges are allowed in the prefix.
îš„ A numeric range is allowed in the number of additional digits.
Note: The prefixes must not overlap. Attempting to process an overlapping
configuration by the DConvert utility results in an error message specifying
the problematic line.
An example of a Dial Plan file in ini-file format (i.e., before converted to *.dat) that contains
two dial plans is shown below:
