Header Filter Rules

Header Filter Rules lets you filter out SIP requests based on the contents of the To and From headers. This could be useful if you want to prevent groups of users to make calls through the Telecommuting Module.

Wild cards can be used: * for any number (zero or more) characters, ? for exactly one char- acter.

Requests that do not match any rule are handled according to the Default header filter policy set beside the table.

No.

The No. field determines the order of the rules. Rules are used in the order in which they are displayed in the table; rule number 1 is first. To change order for a rule, enter the new number in the field and press Save.

From Header

Enter an expression which the From header should match. If this rule should match all From headers, enter *.

To Header

Enter an expression which the To header should match. If this rule should match all To headers, enter *.

Action

Select if this rule should make the Telecommuting Module Process or Reject the matching requests. Rejected requests get a code 403 packet in reply.
