I assume with the "lock button" you mean the (hardware) power button?

Calls itself doesn't do any blanking itself. The shell usually does.
E.g. phosh does this *based* on what gnome-calls exposes on DBus *and*
the state of the proximity sensor (also read from iio-sensor-proxy via
DBus).

So the thing to check on your device is what exposes incorrect results
or if the shell interprets them the wrong way.

>From what you write it looks as if your shell assumes the proximity
sensor is on as soon as the first call starts so I'd start debugging
there (e.g. in the case of phosh by using
`G_MESSAGES_DEBUG=phosh-proximity`).
