Image 66: Filter settings and regular expression matching example
In the example shown above, we have defined two filter expressions which are used to match against the
destination caller ID. According to this filter rule, all calls placed to phone numbers starting with +15 and Skype
account names starting with the name “shrek” and followed by zero or more digits [0‐9] will be denied. For
example, calls to +1 (515) 978‐1234 or to Skype accounts with user name “shrek”, “shrek1”, “shrek2”, etc. will
be denied for all callers. Alternatively, we could define a specific user or a group of users to restricting outgoing
calls using the “Apply This Rule to” field.
