The High Frequency Communications system (HF) must have SELCAL capability to process the ground station contact and alert the crew through audio or visual means. This eliminates the aircraft crew from monitoring the HF frequencies on a regular basis and the subsequent background noise as a result. Selective Calling or SELCAL is a technique by which an aircraft has a unique identifier and a ground station can contact the aircraft for communication.

But the number of unique tone combinations using QCI is limited compared to QCII. What happens is that the unique 2-tone combination in the QCI tone set is used to activate 2-tone pagers. Oh yeah, you don't find too many pagers equipped to decode QCI, either. I think that over the years it was discovered that 2-tone signaling (Quik-Call II, Plectron, etc.) was secure enough for public safety, so QCI is not as much in use as it once was. The original Moto Quik-Call I system was developed to provide a very secure alerting system to prevent accidental tripping, and was very robust. So, if departments used PL for monitor and siren activation, there would be sporadic cases of sirens blowing and pagers beeping because of far-away transmissions on the same frequency. But, PL is widely used on public safety channels, and if you have skip (low bands particularly) it is not unusual to have another user coming across with the same or similar PL. And it has to be continually present to keep the squelch open. PL is not susceptible to falsing because the tones lie below the 300-3000 Hz frequency range, and the tone detect tolerance is very tight.

Statistically, there are some combinations of human voice characteristics plus background noise that can cause a 2-tone decoder to trip, but the probability is very small. The real answer to this question, I think, is that two-tone decoders are much less susceptible to falsely decoding voice and/or other noise on the channel than other methods of signaling.
