Grasshopper is a virtual phone system aimed at solopreneurs and small businesses that want a professional business number without new hardware. It offers toll free, local, and vanity numbers, custom greetings, voicemail transcription, call forwarding to a personal phone, and unlimited users and extensions on its higher tiers.
