A method and system are described for servicing a second line service (“SLS”) based communication request originating from a subscriber's telecommunications device (“TD”) even if the call signal does not include sufficient information to identify the phone number from which the subscriber initiated the call. The method involves associating the SLS phone number of the subscriber, the primary number of the subscriber and the primary number of a third party via a special relationship number.
