  • What Does NUSO Mean? +

  • Pioneer360,
    We want to take a moment and give a huge shout out and thank you to NUSO! Today, we simultaneously ported over 88 phones at 7 different locations to a new Unified Communications as a Service System, all in under 30 minutes. This was by far the largest and easiest transition we have done in our 15 years in the telecommunications business. So, thank you, NUSO, we are beyond thrilled to be partners with such a terrific company!
