"911 doesn't ring sometimes" in this context means that there's good signal and can call non-emergency numbers using ordinary phone networks, but for some reason can't handle emergency calls correctly (and yes, you could call the GSM-wise non-emergency but legally-wise long emergency number for your area normally, it's just you're more likely to not know it in an actual emergency).

I'm wondering if their 911 service is having problems as a result. If that's the case then it's more of a "try not to need 911, but if you do try to use another network"

This won't solve 100% of cases, but when in doubt (and if life or limb aren't at risk), can't you call 311 and let them tell you, if necessary, to hang up and dial 911 instead?

Just because the call isn't to 911 doesn't mean it wasn't an emergency call.
