When should a business switch from VoIP to UCaaS?

Question

Accepted Answer

Switch from standalone VoIP to UCaaS when employees are running 3 or more disconnected apps for calls, video, and chat, when remote staff exceed 30% of headcount, or when the current VoIP contract is within 12 months of renewal [1][2]. If the only need is dial tone for under 10 in-office seats, basic VoIP still wins on price [3].
