Ask HN: Is anyone using IfByPhone or Grasshopper?
I'm looking at virtual phone systems, and either these two are very new or they both hired Don Draper clones and suddenly are appearing in lots of ads on my favorite websites.
Is anyone here using a virtual phone system such as IfByPhone, Grasshopper or another? If so, what are the pros and cons for your company having moved from a physical PBX&/IVR infrastructure?
