Dialogic® Diva® SIPcontrol™ Configuration

Dialplans

With help of the local phone settings, Diva SIPcontrol is able to convert a received call address to a normalized

form, e.g., the E.164 format. This not only eases the definition of subsequent conditions or maps, but it also

converts the call to the format 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 can be used.

• Adding and removing the line access code: If not present, dialed numbers are automatically prepended by

the digits needed to access the public telephone network.

• Support for the North American numbering plan: Up to 10 area codes can be configured to be treated

differently. For example, in many areas, dialing into neighboring areas does not require dialing 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 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 of 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 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.

• Diva SIPcontrol's number normalization function does not remove outside access digits as a PBX can do

for external calls. If Diva SIPcontrol 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.

To add a dialplan, click the Add button. To change the configuration settings, click the Details button on the

right hand side. To open the online help for a specific parameter, click the parameter, and a window with the

help text will appear.

Update Interval (sec) Update interval in seconds for the cache. The longer the update time, the longer the

data is kept in the cache. It is recommended that you leave the default value. A long

update interval takes more time to update because of the big cache, but a short update

interval uses both Diva SIPcontrol resources and LDAP server resources too often.

Default is 86400 seconds.

Persistent Save If set, the gateway accesses the persistent cache first without connecting to the LDAP

server. If the next update time is within the range configured in Update Interval (sec),

the gateway uses the saved cache; otherwise, it tries to connect to the LDAP server in

order to update the cache.

This option is not set by default.
