It's easy enough that my office manager can set up new users without me having any training! I like how it integrates with our Google Apps so we don't have multiple accounts/phones numbers if someone leaves or transfers out of an account etc.. The price point was great too!! We were able use this service as part time employees while waiting until fulltime staff could be hired - which took several months longer than expected because they had some issues finding qualified candidates (that weren’t already working elsewhere).
