Smallest possible rule to match ten different From numbers?
I have ten different From number that I want to set as anonymous.
How can I match ten different from numbers in the smallest possible rule?
Basically:
header-rule
        name                                    lookForFrom
        header-name                         From
        action                                   store
        comparison-type                    pattern-rule
        msg-type                               request
        methods                                INVITE
        match-value                           ^sip:1 OR ^sip:2 OR ^sip:3 OR sip:4 ...
        new-value
