supports describes the number that was asked about, NOT one of your own
lines. It is a point-in-time answer rather than a property of the number:
someone who changes device or turns a service off stops being reachable, so
treat a true as a strong signal for picking a channel, not a promise that a
later send is delivered.
The answer to "what can this number receive?".
