Adding VoIP to discord

Discord should have an option to add VoIP numbers to accounts as a paid tier for businesses. That would make discord the perfect chatting platform for every scenario. Right now the company I am with is sitting between switching to discord or staying with our previous Application due to needing to use the VoIP functionality in there for our clients. If Discord added this functionality it would be perfect to use for us and many other businesses as well. Discord hasn't really stepped into the business market yet but they are desperately in need of chat apps of the like but with VoIP functionality.
