I am in love with OnSIP, It has simplified my life!

My experience has been great with OnSIP. They have exceptional customer service I've received exactly what I needed each time. I have a personal coach who checks in with me every so often to ensure that things are going good as well. I highly, highly recommend using this cost effective service for your at home business!

Pros

I love that I can now add business lines into my home office for a fraction of the cost of doing it through the local phone company and I have clear crisp phone service. Everytime I have needed customer service I have had an excellent experience and they have taken care of each issue with great care and speed getting me back online and going again quickly. With my home office phone I can have up to 4 lines (depending on the phone you can have many more) and I can tell which is ringing so I know how to answer properly and helps me to be more professional. So, so much easier than having my cell phone ring all the time.

Cons

It doesn't have a texting feature, I just use Google Voice to get this feature it just means that I have to have 2 seperate numbers for my business.

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.

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.

Pros

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.

Cons

Nothing comes to mind. I have no issues with this service.

We have been using Onsip Voip phone system since 2016, it is simple, but robust system, and good

Pros

(1) The most we like Onsip is its Basic Plan which provide using call per minute rate instead of call per user rate since we have many users, but our call volume is very low. From the voip market, many companies only provide per user rate.
(2) OnSIP has a robust and knowledgeable support team who provide helps and solution very fast without extra charge.
(3) The Voip system is simple yet comprehensive, complex theories are integrated into simple and easy operations, OnSIP has all the functions we need, therefore, we have used this system for 8 years.
(4) can Access to user-friendly and streamlined experience for admin account anywhere.

Cons

Sometimes, Mobile app on the mobile phone sometimes has network connection issue.

From set up to ongoing service, they have been fabulous to work with.
Phone system is adequate, probably more than we need, but has a lot
of capabilities that you can grow with.

Pros

The customer service is phenomenal. They are always available and it
does not matter who answers the phone, they always make sure that
our problem is resolved at the end of the phone call. Most of the time
I am able to go in on our account and fix it ourselves, I am more
comfortable calling and having them help me and they never make
me feel bad. Awesome customer service.

Cons

The admin website is a little intimidating, I don't always know how
to navigate through it.

Flawless service and support. I know when I pick up my phone it will work.

Pros

Excellent customer service. When I first signed up for them, it was my first foray into the world of VoIP. The customer service team is extremely knowledgeable and patient.

Cons

I do wish they would invoice on a monthly basis versus pay per use/min. It’s not a dealbreaker by any means but it does require a linked credit card to automatically keep your service.

Overall, I have had a good experience with OnSIP. As long as I refresh the application multiple times daily on any device on which I use it, it works great!

Pros

Cons

Customer service is sometimes a bit counter-intuitive.

Their exceptional customer service and feature-rich platform has been a major benefit for our company. While there's always room for improvement, like having a more intuitive search function for call transfers, the overall value and reliability of OnSIP make it a great VoIP solution.

Pros

OnSIP's web portal and mobile apps are known for being user-friendly for both administrators and regular users. If you found the system easy to navigate and manage, this is a noteworthy advantage.

Cons

While OnSIP offers a wide range of features, finding contacts for call transfers could be smoother. Ideally, a more intuitive search function within the existing contact list would expedite the transfer process.

OnSIP is great to work with. They are always there to help out and get something resolved. We have implemented several installations with them and the ease of use is amazing! Being able to setup the entire install from my desk before we go is also a very solid plus.

Pros

I have used OnSIP now for several years. In that time I have had very few issues that weren't my fault. In those times, the customer support team is right on it with their help, even those times it was my fault, they still helped very quickly. As well, the service is very easy to use, the quality of the interface is spectacular and implementation process was simple. I can't say enough about OnSIP and how great of a company they are. The best part is our clients get a great product at half the cost of some of their competitors.

Cons

Ring tone assignment isn't available, which is a very small issue but it did effect us in a small way. Other than that I can't think of anything.
