Software is able to convert a received
call address to a normalized form, e.g., the E.164 format. This does not only ease the definition of subsequent
conditions or maps, but it also converts the call to the format as required by the receiver.
The dialplan module supports the following features:
• Number expansion and reduction: called, calling, and redirected numbers are converted to one of the following
formats: international, national, local, or internal (extension-only) format; for each format, either prefix digits
or digital number type flags may be used.
• Adding and removing of the line access code: If not present, dialed numbers are automatically prepended by
the digit(s) needed to get access to the public telephone network.
• Support for North American numbering plan: Up to 10 area codes may be configured to be treated differently.
For example, in many areas dialing into neighboring areas requires to not dial a long-distance prefix.
Important information about the outside access digit configuration
• Configure the outside access digit only if there is a PBX between the PSTN and the Diva SIPcontrol software,
and if this PBX requires the outside access digit for external calls. If you need to configure the outside access
digit, also configure the following related options:
•
Incoming PSTN access code provided by the PBX
:
This option defines if the Diva SIPcontrol software
expects the outside access digit in the calling number in external calls from the PBX.
The PBX normally prepends the outside access digit to the calling number of incoming external calls in
order to enable callback functionality at internal phones. If this is the case, enable this option.
•
PSTN access code provided by the SIP caller
:
This option defines if the Diva SIPcontrol software
expects the outside access digit in the called number of external calls from SIP to the PSTN.
It is normally required to prepend the outside access digit to call an external number from an internal
phone, in this case, these are phones on the SIP side; however, in some configurations this is not required,
such as a configuration that is part of the North American numbering plan (NANP), where an internal
number can be identified based on its length. If it is possible to identify an internal call purely by the
length of the called number, this option can be disabled. In all other configurations with outside access
digits this option has to be enabled.
It is recommended to have this option enabled in dialplans with the outside access digit set.
• The Diva SIPcontrol software's number normalization function does not remove outside access digits as a
PBX can do for external calls. If the Diva SIPcontrol software needs to behave like a PBX with an outside
access digit for external calls, use the Address Map functionality in combination with a Routing module.
