On my WhatsApp profile, one of my tag lines is "Hater of the 'What Do
You Do?' culture and WhatsApp Calling". I detest both equally.

But focusing on the latter, if you call me on WhatsApp, I'll cut you off
and call you back via GSM. The only time I'll entertain any WhatsApp
calls is if GSM coverage is poor, or if I know you are traveling and
can't roam, but have wi-fi.

I'd never blame my mobile providers for poor quality WhatsApp calls, nor
would I do the same to my ISP. I have zero patience for WhatsApp voice
calls to sort themselves out when initiated, and yet plenty of people
enjoy using it for whatever reasons, mostly to "save money". Personally,
wasting time exchanging "Can you hear me now?" is more costly than
having a short and concise call over GSM. If we are going to talk for
hours, let's have a beer.

The point is, as much as some "critical" conversations (want to) take
place on WhatsApp, Facebook have zero control of the quality of that
experience once the bits leave their data centre. I don't know if they
will ever fix that given all the variables that exist thousands of miles
from where the service is hosted, but you might not be forgiven for
thinking you can run a voice-based business on WhatsApp. In fact,
recording a voice note and sending it via WhatsApp is like two-way
walkie-talkie radio, but perhaps more reliable :-).

I really don't know how to fix this for hospitals relying on best-effort
infrastructure to deliver critical, priority services to their patients.

Mark.
