I have a medical supplies startup in the USA and have raised 75% of my target in a seed round. I also have a brand identity and logo paid for by my accelerator. We are starting business cards, we have a website, but I haven’t committed to a business phone number yet. I think it’s time to get one. I am the sole employee now, but anticipate hiring sales reps in the next 90 days.

What free/low-priced phone services have you used or do you recommend? Is there any reason to choose anything other than Google Voice? Thanks.
