Multiple Parameters in Fraud Protection

We regularly use the Fraud Protection feature to block in bound SPAM callers.
This question is, can we have multiple parameters.
What I am after is block caller from xxxxx calling into yyyyyy
Example of what I am thinking is,

<userEntry>

    <from-phone-number>495*</from-phone-number>
    <to-phone-number>34917*</to-phone-number>

     <realm>*</realm>

</userEntry>

So that would be block all calls from German with area code starting 5, when trying to call into Spanish number are code 17 (Madrid)of

Is this concatenation for from and to allowed.
