I like that Phone2 allows us to have multiple phone numbers inside the same account or workspace, which is really helpful as we're expanding our offices. We have an office in Los Angeles and we're soon opening in Las Vegas, so being able to quickly obtain a local number in just a few clicks is great for our phone-heavy operations. Also, the initial setup of Phone2 was very easy and quick, taking only about five to ten minutes, after which I was able to immediately start inviting our paralegals.
