7.4 Dial Plan File
The Dial Plan file contains a list of up to eight dial plans, supporting a total of up to 8,000
user-defined, distinct prefixes (e.g. area codes, international telephone number patterns)
for the PSTN to which the device is connected. The Dial Plan is used for the following:
ISDN Overlap Dialing, FXS, and FXO collecting digit mode (Tel-to-IP calls): The file
includes up to eight patterns (i.e., eight dial plans). These allow the device to know
when digit collection ends, after which it starts sending all the collected (or dialed)
digits (in the INVITE message). This also provides enhanced digit mapping.
CAS E1 MF-CR2 (Tel-to-IP calls): Useful for E1 MF-CR2 variants that do not support
I-15 terminating digits (e.g., in Brazil and Mexico). The Dial Plan file allows the device
to detect end-of-dialing in such cases. The CasTrunkDialPlanName_x ini file
parameter determines which dial plan (in the Dial Plan file) to use for a specific trunk.
Note: To use this Dial Plan, you must also use a special CAS *.dat file that supports
this feature (contact your AudioCodes sales representative).
Prefix tags (for IP-to-Tel routing): Provides enhanced routing rules based on Dial Plan
prefix tags. For a detailed description, see Dial Plan Prefix Tags for IP-to-Tel Routing
on page 418.
The
Dial Plan file is first created using a text-based editor (such as Notepad) and saved
with the file extension *.ini. This ini file is then converted to a binary file (*.dat) using the
DConvert utility (refer to the Product Reference Manual). Once converted, it can then be
loaded to the device using the Web interface (see ''Loading Auxiliary Files'' on page 337).
The Dial Pla
n file must be prepared in a textual ini file with the following syntax:
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 (',').
Empty lines are ignored.
Lines beginning with a semicolon (';') are ignored.
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.
Asterisks ('*') and number-signs ('#') can be specified as part of the prefix.
Numeric ranges are allowed in the prefix.
A numeric range is allowed in the number of additional digits.
Notes:
• The prefixes must not overlap. Attempting to process an overlapping
configuration by the DConvert utility results in an error message
specifying the problematic line.
• For a detailed description on working with Dial Plan files, see ''External
Dial Plan File'' on page 415.
