Can the emergency elevator phone use VOIP/Internet to call out for help?

If so, can you recommend what equipment, module, service you would use?

Would you just connect it to a Ooma or magic jack, something like that or is there a better way to do it?

My building has 24/7 Internet connection so I was thinking instead paying for a phone line that is never used, maybe it could go out over the internet via VOIP.

Thanks.
