I strongly recommend it to anyone who makes external calls for work!

I couldn't imagine using my personal phone number at work both for my own privacy but also because I never pick up all the spam calls I receive. OpenPhone allows me to sift through what calls I need to answer just by separating out personal vs professional. I strongly recommend it to anyone who makes external calls for work!
