For 6 years now, UnitedCall has supported me with steadily increasing quality and sensible options for the individual configuration of my requirements for a smoothly functioning back office at a more than good price-performance ratio. I unreservedly recommend UnitedCall and will certainly remain a customer until my retirement - which is still a long way off!
