Pros / Cons
  • Through the use of mobile apps and video conferencing, our ability to broaden communications within the company, outside vendors and partners has simplified our unique hybrid office platform.
  • Can't figure out how to set a different and unique ring tone for my cell phone to let me know it's the "office line' ringing.

  • Manageable Learning Curve While some advanced call-flow features take a little time to understand, the documentation is excellent. Once you learn the layout, everything becomes second nature.
  • There is nothing I dislike about On-Sip other than I wish I knew about them sooner, especially when I think about all of the money wasted with other VOIP companies that cost twice as much and offer and offer half of what they do.
