Reliable and affordable service. Great tech support on the rare occasion I need it. Service support hours accommodate users regardless of location.

Cons:

Reasons for choosing OnSIP

Good reviews. Online research and non high pressure sales approach OnSIP customer service person took in discussing our needs.

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.

Customer support

Functionality

Pros:

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.

Cons:

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.

Reasons for choosing OnSIP

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

Clunky UI, functional

It functions for day to day use, certain elements and features could be cleaned up and made to be more intuitive. We have had to stall rollouts several times when features stopped working. Customer service is excellent and very communicative. They work to get to the bottom of any issue and stay in touch until its resolved

Pros:

Multiple options for routing phone calls to various platforms, excellent customer service, relatively easy to provision and connect lines

Cons:

The admin portal UI is clunky and not the most intuitive. Search is sometimes difficult if you don't look for a specific data element. Navigating between users and resources creates extra stepsWeb and mobile apps look clean but many features are often not working and sometimes notifications for calls don't come through at all. Call history is sometimes inaccurate. App navigation is also not the most user friendly - we generated our own tutorial to explain how to use various features.

Pros:

On-Sip has a Great product, Great customer service, and a Great price. We have been uning On-Sip going on 5 years and we recommend them diligently.

Cons:

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.

Reasons for choosing OnSIP

Customer Service was much better. Eager people willing to help us.

Reasons for switching to OnSIP

They always made mistakes and were getting very expensive. They also constantly added services with out permission.

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.

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.

Reasons for choosing OnSIP

We knew the individual who recommended the product and is available to help.
