DomainToPhone Whois

From Paterva Wiki

This transform performs a recursive whois query on the supplied domain and parses the output for phone numbers. The idea with the transform is to provide the phone number of the owner of the domain. The whois information itself is stored as a property of the domain ('Domain Whois'). You should always manually inspect this data to give context to results - or see if the parsing of the phone number failed (it is difficult to correctly parse all forms of phone numbers). For more information about whois see the Wikipedia entry here [1].
