Chapter 11. SIP Traffic
Matching From Header
Here you create criterias for the From header of the SIP messages. This is used when match-
ing 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.
