Competitive pricing Competitive pricing. Particularly the pay as you go plan makes this an option for slightly larger companies where an inflated flat rate per extension is too prohibitive. Another plus is the reliability. We're had no system outages since switching to OnSIP.

We updated our Router and we no longer… We updated our Router and we no longer had inter-office communication. The new router was blocking the connections. After several trial and error attempts, they figured out the solution. It was great to see them continue to try and resolve the issue.

I have been a customer since early on… I have been a customer since early on in the start of Onsip. Onsip was always reliable. And with whatever rare times that I did need my handheld, the support personnel at Onsip were always great to work with.

Great customer service, love the voip Had a problem with one of our base phone and all of our cordless. Call CS and got a tech immediately. He was great, issue on base was just a matter of changing its setup and cordless just had to be rebooted. Tech walked us through solution for each so we would know what to do if it happened again. Have had very few minor issues over the past year of using Onsip. Customer service is very quick to respond and very knowledgeable. This voip phone system has been great for our business.

Updates on the fly So, tasked with revamping our existing phone extensions and menu options I called Eden Harvest (by the way the best in the business) and he set aside his time for me and helped me walk through each step till I got it just the way we needed it, and he did our newest recording as previously he did. So, love working with him and OnSip. I learn something new this company does every time we need something.
