Thanks for your question. There’s plenty of alternatives to Google Voice for Business but our favorite has been Kall8 for providing standalone, professional-facing 800 numbers that we can forward to our business cell phones. They’re economically priced, send us call notification emails, and much more. You can check out their full list of included features here. Please let us know which one you decide to go with so we can keep our advice up to date. Chau!
