Phone companies are required to make sure 911 works on their phones. Random people on the internet aren't required to make sure 911 works on random apps, even if they look like phones.

The comment you're replying to literally has an example of an internet calling service being fined $20,000 for not properly directing 911 calls.

I guess Vonage should try to appeal the case and say pocksuppet said they're not required to do that.

Vonage sells phone services that happen to use the internet. This is not the same as being WhatsApp.
