The front desk is the most guest-visible radio position in the hotel. A loud speaker, a squelch burst or a shouted reply is immediately noticeable in the lobby. The radio has to work like a discreet earpiece, not a walkie-talkie on the counter.
At the same time, the front desk is the hub for room moves, luggage, taxis, VIP arrivals and emergency coordination. The configuration has to keep the audio private without slowing down the response.
