Painless Migration.

Clear communication and timelines, zero hitches porting numbers over. Made it easy to convert from onprem PBX to cloud hosted VoIP service. Planning on implementing at other locations using OnSIP due to this experience.

Jonathan

Easy to use.

I have used OnSIP for over 10 years and have to say this is the easiest most robust VoIP service out there. I used their system with 5 employees or 50 with the same ease.

From the time I found out that my small business needed a new phone system to the time that we were up and running with OnSIP I could not have asked for a better transition. I came into some hardware problems which were solved by my rep who put in several hours of troubleshooting to leave me very satisfied. She went above and beyond. I have already recommended them to several of my colleagues.

Always amazing customer support. My favorite thing about OnSIP. Customer service won't quit until your problems are solved. It's amazing. Thank you so much.

From planning to implementation and support, I've been very happy with our experience with OnSIP. I felt well supported every step of the way. Pricing is very competitive as well! I wholeheartedly recommend!

Andy Loyd

Great VoIP system that works seamlessly on a physical phone, MacBook, and the OnSIP App on my iPhone and iPad. Easy to configure for user settings.

Stewart McMillan

Excellent Support.

You have amazed me every time I have needed help day or night holiday or weekend. Your tech support is excellent.

Tim C.

VERY satisfied customer for almost 2 years. Great product, great service. Knowledgeable LIVE support like this is unheard of these days. Amazing.

Chip

Managing this VoIP system is easy and intuitive. I felt like an expert after a few days. When I do need help, their staff is awesome. If they don't have an answer immediately, I get one within an hour or so. It works with several different phone manufactures which gives you great flexibility with what equipment you use. I couldn't be happier with the system.
