your testing methods are flawed.
as the signal degrades from your wifi connection, the phone will seek out for a cellular connection. if you discontinue the signal before it tries to connect elsewhere, of course the call will drop... just like if you were on a non-wifi connection.
it does not maintain a connection to both cell and wifi at the same time... if it did, then your method of testing would end in a positive result.
