Dialing Plan

The Dialing Plan object provides the ability to override the dial plan normally used by the MetaSwitch NE to interpret dialed numbers. This allows the use of additional codes specific to the Business Group, defined by the Dialing Plan's child objects.

The Dialing Plan is a child of the Business Group object. There can be at most one Dialing Plan object for each Business Group.


If you do not configure a Dialing Plan object, or if you delete an existing one, the users within the parent Business Group will be unable to make outgoing calls or calls within the Business Group (although incoming calls will still be accepted).

Object-Specific Actions
Generate Diagnostics Log To generate diagnostics log data about the Dialing Plan, click on this pushbutton. Normally you will only need to do this if requested by MetaSwitch support personnel to help solve problems with your dialing plan configuration. This information is written to the NE's standard log database, but is intended for use by MetaSwitch support personnel.

Access

Description
External line code Change The code that a subscriber in this Business Group dials to obtain an external line (for a number that is not an intercom code or short code). Specify a code consisting of 1-5 characters corresponding to telephone keys; the first character may be #, *, or one of the digits 0-9, and any remaining characters must be digits 0-9. The default is 9. This code must not match any Short code or any value in an Intercom Code Range defined for this Dialing Plan. To use Assume 9 dialing, delete any existing value and leave this field blank. You also need to configure the Business Group Number Blocks in this Business Group to use a Subscriber Group with an appropriate Digit Map for Assume 9 dialing. See the Knowledge Base on the MetaSwitch Customer Portal (http://support.metaswitch.com) for more information. If the Business Group includes SIP subscribers, the code must not match the initial digits of any Call Services access code or vice versa. For example, do not configure an external line code of *3 if you use *345 for an access code, and do not configure an external line code of *88 if you use *8 for an access code.
Simple matching automatically applied Read only Specifies whether the NE has switched automatically to the use of simple digit matching to interpret codes dialed by subscribers in this business group. The NE uses simple digit matching automatically when the business group's dialing plan configuration becomes large and complex; it reverts to the standard digit matching process if the configuration is simplified. Simple digit matching reduces the size of the dialing plan configuration data, but means that dialed codes are recognized only after a 4-second delay or a terminating # character (instead of being recognized as soon as they are dialed). Values:
  • True
    Simple digit matching has been selected automatically.
  • False
    Simple digit matching has not been selected automatically. The Force simple matching field can be used to switch between standard and simple matching if required.
Force simple matching Change Some Access Devices may have difficulty in matching dialed digits correctly to a Business Group's Dialing Plan using the standard digit matching process. In these cases, this field allows you to force the use of simple digit matching. Use this option if you are having interoperability problems with access devices, or as recommended by your MetaSwitch support personnel. If the Simple matching automatically applied field is set to True, this field is read-only because you cannot override the automatic selection. Values:
  • True
    Use simple digit matching.
  • False (default)
    Use the standard digit matching process.
Diagnostic log correlator Read only Identifier of the log message for the most recent diagnostic log data created by the Generate Diagnostics Log pushbutton.
