How Numbers Are Processed

Diva SIPcontrol provides two mechanisms for number processing. Both mechanisms can be used together:

1. Number Normalization Based on a Dialplan as described below.

2. Number

Modification Using Regular Expressions as described on page 78.

Number Normalization Based on a Dialplan

The number normalization based on a dialplan can work in an environment in which Diva SIPcontrol is connected

to a private SIP network and a public switched telephone network (PSTN), optionally with a PBX between the

PSTN and Diva SIPcontrol. If Diva SIPcontrol is used as a gateway between a private circuit switched network

and a public SIP-based network, the number normalization function of Diva SIPcontrol should not be used.

Diva SIPcontrol also supports dialplans using the North American numbering plan (NANP). See North-American

numbering plan: on page 52 for more information.

Number normalization is done in two steps:

1. The received called, calling and redirected numbers are analyzed based on the dialplan configured for the

PSTN Interface or SIP Peer.

2. The number is converted into the configured target result. Six target results are available:

• International number with prefixes: All numbers are converted to an international number with the

prefix for international calls and, if required, an outside access digit.

• International number with number type: All numbers are converted to an E.164 number with the

number type flag set to "international" ("+" is used in SIP addresses).

• National number with prefixes: If possible, all numbers are converted to a national number with the

prefix for national calls and an outside access digit, as required. Exception: Numbers with a different

country code will be converted to an international number with a prefix for international calls and an

outside access digit, if required.

• National number with number type: If possible, all numbers are converted to a national number with

the number type flag set to "national". Exception: Numbers with a different country code will be converted

to an international number with the number type set to "international". Note: This target result should

not be used for calls to SIP networks.

• Extension only with prefixes: All numbers are reduced as much as possible; only the required prefixes

are prepended.

• Extension only with number type: All numbers are reduced as much as possible. Instead of prefixes,

the appropriate number type is set. Note: This target result should not be used for calls to SIP networks.

Important Information about the Outside Access Digit Configuration

• Configure the outside access digit only if there is a PBX between the PSTN and Diva SIPcontrol, 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 whether Diva SIPcontrol

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 in 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 whether Diva SIPcontrol expects

the outside access digit in the called number of external calls. It is normally required to prepend the

outside access digit to call an external number from an internal phone. 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.

Enable this option if the internal users that use SIPcontrol for external calls prepend the outside access

digits in their calls; otherwise disable it.
