Room for improvement

Customer Service takes the win

Overall? Very happy! If they didn't have quick, knowledgable, human customer support, I would probably find another tool. But their team does a fantastic job to listen, educate, and help managers understand the tool.

What they liked
  • Customer service is FANTASTIC
  • Every call I get knowledgable, smart, problem-solving people that actually listens, hears the problem-solving I've done, and helps me not only to find solutions, but walks me through so I have more knowledge to solve it myself
Room for improvement
  • Still has residual "third-party app" feel - mobil is very buggy, signing in/out on multiple devices can be tedious
  • If I lock my computer screen, I often need to restart the app to get it working
  • For some reason wifi calling has difficulty with landlines (bad connections), but this might not *necessarily* be onsip's fault
Why they chose it

"For price and offered services, OnSIP seemed to be the best match with our current size (2-5 people using it), input, and work stations"

Outstanding customer service

We don't use the system to the extent that I am sure we should. But it takes care of the current needs and can be expanded as we need more unique services.

What they liked
  • Customer service is top of the line
  • There has never been a time when I called and did not receive help or the solution to whatever my issue was
  • Everyone is professional, courteous and willing to go above and beyond
  • Truly outstanding in today's world
Room for improvement
  • Sometimes it is not easy to understand how to make changes to our system
  • I would say semi user friendly but customer service more than makes up for that

Room for improvement

random but usually small glitches that are hard to explain to users but usually never interrupt the flow of work

Switched From

too many disconnections and problems with phones/IPs

Why they chose it

First Rate Service

All positive. They have helped me configure my phones, set up extensions and with any issue I have come across in my time as a customer. I do not have many issues, but there have been a few, and every time I get resolution in one contact. Pretty impressive.

What they liked

If you need customer service for any issue you can get a human immediately an chances are they can figure it out to resolution with one point of contact

Room for improvement
  • Nothing comes to mind
  • I have no issues with this service
Switched From

Too costly kept failing. Not able to get fiber at our site/

Room for improvement
  • The jargon
  • Normal people don't know the terms used
