Onyx Phone vs RingCentral
RingCentral is one of the biggest business phone companies, with video meetings, contact center software, and a long list of add-ons. Onyx Phone is a smaller, simpler phone for teams that answer one shared business number. If you need RingCentral's breadth, it's worth the price. If you need a phone that rings and texts, you may be paying for a lot you won't use.
