Great for mobile office
I use this app daily. I am in and out of the office so much, this app helps me stay connected with my clients. I can get voicemail, make and receive calls and update my voicemail greeting. This way I can keep my personal phone number and work phone number separate but on the same device. In the past I had carry around two cell phones, it was so cumbersome and such a hassle. Now this app integrates perfectly with the voip service I already have.
