Chapter 11. SIP Traffic

Matching From Header

Here you create criterias for the From header of the SIP messages. This is used when matching requests in the Dial Plan table. For a request to match, all criterias must be fulfilled.

You can enter a username and domain or create a regular expression (reg exp) to match the From header.

This table is only available when the Advanced SIP Routing or the SIP Trunking module has been installed.

Name

Enter a Name for this From header pattern. The name is used in the Dial Plan table.

Username

Enter the username that the From header should contain. You can enter "*" to match all usernames.

Domain

Enter the domain that the From header should contain. You can enter "*" to match all do- mains.

Reg Expr

Instead of entering a username and domain, you can create regular expressions to match the From header.

This column is only available when the Advanced SIP Routing or the SIP Trunking module has been installed.

Read about regular expressions at http://www.regular-expressions.info/. 3Com VCX IP Telecommuting Module supports Extended Regular Expressions.

Transport

Select which transport protocol or protocols this should match.

Network

Select from which network the SIP traffic should be sent. Select from the networks created on the Networks and Computers page under Network Configuration.
