The GetAddress method can be used to determine if a phone
number is associated with a mobile device and obtain the email
address for the wireless service provider's gateway. This is done by
sending an query to a server that will check the phone number against
a database of known providers and the phone numbers that have been
allocated for wireless devices.
By default, this method will attempt to automatically determine
which service provider is associated with the phone number. If the
service provider cannot be determined, this method will fail and
return an error code. If the Provider property has
been set to to the name of a specific service provider, that provider
will be used to determine the gateway email address.
This method sends an HTTP query to the server api.sockettools.com
to obtain information about the phone number and wireless service
provider. This requires that the local system can establish a standard
network connection over port 80. If the client cannot connect to the
server, the method will fail and an appropriate error will be
returned. The server imposes a limit on the maximum number of
connections that can be established and the maximum number of requests
that can be issued per minute. If this method is called multiple times
over a short period, the control may also force the application to
block briefly. Server responses are cached per session, so calling
this method multiple times using the same phone number will not
increase the request count.
