Used by the routine at 30675. On entry, A holds the identifier of either the telephone that Sam is holding (which was ringing when he picked it up), or the telephone that Sam is calling. If there is a message for Sam, it will be queued unless Sam needs to identify himself first, in which case message 37 ('A VOICE SAID 'WHO'S THERE?'') will be queued instead. If there is no message for Sam, the message that is queued will depend on who Sam is calling (Daisy, the police, or someone else).
