Apparatus and method for qualifying telephone numbers for a telephone network |
摘要 |
An apparatus and method for qualifying telephone numbers for a telephone network according to whether the telephone network services the particular area associated with a dialed telephone number, and whether the dialed telephone number is associated with a particular type of terminal equipment. The method according to the present invention comprises the steps of: monitoring a telephone line for outgoing calls; intercepting an outgoing destination telephone number on the telephone line; comparing the outgoing destination telephone number to at least one destination telephone number stored in a database; making a connection between the telephone line and a selective telephone network if the outgoing destination telephone number matches the at least one stored destination telephone number; and making a connection between the telephone line and a standard telephone network if the outgoing destination telephone number does not match the at least one stored destination telephone number. In the event that a connection is made with a standard telephone network, the telephone line is monitored for activity and if activity is detected, the outgoing destination telephone number becomes qualified and is then stored in the database.
