### "One of the best and most trusted VoIP services"

April 10, 2018

5.0

One of the best VoIP providers in terms of service, features, ease of use, and price. I can wholeheartedly recommend them to anyone looking for a reliable VoIP vendor.

Pros

Very easy account setup and clear instructions on how to use the service itself. The pricing is wonderful so it definitely won't be a big budget burden. Good sound quality for the price. The support is also very responsive, at least during the several times I needed to reach them.

Cons

I have had an issue using my account in a 3rd party VoIP software. It is not directly OnSip's fault, but I wish they had more tutorials for external popular software. They were also using Java to make calls from their own site, which might be a security concern for some.

### "Easy to use, convenient"

June 1, 2023

5.0

Pros

I love that I receive an email saying I have a voicemail-I can easily listen to the message from my computer.

Cons

I was making a leaving a message and received an incoming call-it kept beeping and it was confusing how to navigate this situation. Not sure if the message took or was interrupted by beeping telling me I had another call coming in.
