Address Normalization
You can configure the following parameters in the Address Normalization section when you define or modify
a SIP Peer:
Minimum session
expires:
If Use session timer is enabled, you can set a time in seconds between two session refresh
messages that Diva SIPcontrol will accept. The minimum value is 90 seconds.
Dialplan: Select the local dialplan to be used by the dialplan module of Diva SIPcontrol. Configure the local
dialplan under D
ialplans, as described on page 51, before you select it here.
The dialplan selected here applies only to outgoing calls.
Number format
(outbound):
This parameter determines the shortest format allowed that is sent in calls to this SIP peer. You
can modify this parameter only if you selected a dialplan from the drop down menu. The following
options are available:
• Unchanged: The number signaled in the SIP message will be used unchanged for dialing.
• International number: The number is always converted to an international number, including
country and area code.
• National number: The number is converted to a national number unless it is an international
number with a different country code.
• Extension: The number is reduced as much as possible. An internal number is reduced to its
extension only.
For more information about number formats, see How Numbers Are Processed
on page 77.
Encoding
(outbound):
Determines if numbers in calls to this SIP peer should either be encoded as unknown numbers
with national or international prefix digits or as national or international numbers with type flags.
Address map

Name of the regular expressions list applied to the addresses received on calls from this SIP peer.
See Address Maps

Regular expressions can be used to add or remove dial prefixes required by a PBX or to rewrite
public phone numbers of different number ranges into a common format. See the Examples
on
