Yes it does. I fitted a switch in its DC power supply to disable it
when expecting a call it would block - like say from a hospital
switchboard. Quicker than doing it with their software.

Does the hospital switchboard not present a number that you could
whitelist?

I've got the main one listed. But they may have outgoing lines which
appear as a different number to it.


If they have set up their hospital switchboard correctly, then
even the direct-inward-dialling numbers should only show the
main switchboard number on caller-id, and not the actual number
of that extension.
