Sounds like a problem that should be (rather easily) fixable in the Operating System, no?

If the emergency call doesn’t go through, try the call over a different network. This would also mitigate problems we see from time to time where emergency calls don’t work because the uplink to the emergency call center was impacted either physically or by a bad software update.

Very few phones have the calls handled by the OS. It usually is handled by something called the baseband, which is more like firmware

Yes, seems to be a deficiency in the gsm spec as this affected most/all devices.

I didn’t think this failure mode was even possible.
