I have been using them for 4 years… I have been using them for 4 years using Polycom VVX500, no problems. Just reset my phone today(been using for 4 years) and called support. In the past, I called support 2 years ago and was great. Today, I talked to support, no clue about phone, could not tell what was wrong, could see my MAC address, but could not send config file. Now, I have to look for new provider. Anyone have Ideas. If phone.com has a solution I will stay (if you are reading this). Going to keep till end of month have app on cell phone. Hope this helps.

Don't Use to Conduct a a Business, you will lose customers Anyone considering phone.com as their voip provider needs to look elsewhere. I have been a customer for over 4 years and they completely turned off my ability to text people who have reached out to me. They claim it's due to Federal Regulations but the regulations were never meant as a roadblock to a company that does not engage in sms marketing. My customers who have found me online and have decided themselves to use sms rather than a phone call are completely blocked from receiving a reply. I had many conversations with phone.com customer service agents but it didn't change anything. Now I have customers upset that they are not receiving replies but my hands are tied. Besides the above problem, at least half the time it takes repeated dialing to call someone. The first few times, is just silence. I've even had to use my personal line because it's gotten so bad. Overall, there just have been many other issues along the way which I've tried to overlook. Now, I'm going elsewhere to someone who wants my business.

SAVED MY COMPANY! I don't understand all the negative review's when I got the best customer service ever! Tirthraj and the team at Phone.com are the best. They work very hard to satisfy their customers. I have been a long time customer of Phone.com. Many times I have had trouble paying my bill. They usually work very hard to help me keep it. Unfortunately, I recently lost my business 800 number because I couldn't afford to pay my bill again, this time it was too long. I have had that number for years and it was published everywhere. I don't recommend not paying your bill cause you run the risk of losing it. Sell something, anything, but pay your bill! It definitely hurt my business when I went to run ads and that number was all over the internet. No way can you change decades of publishing and sharing of that number. In both print and online. I really want to thank everyone for getting my phone number back as it was in the process of being assigned to another company. Blessing to you all. Phone.com is the best company for your business.

Phone.com is not for the professional… Phone.com is not for the professional business. Spotty and static phone service makes you look very unprofessional when you use their service, I used one of the vanity numbers paid top dollar and never worked right. When I canceled I told them I want my money back for the wasted time, and the time I haven't used yet and they refused. So now, I have to get the Mad Men involved for the principle of the matter.

Terrible customer service Terrible customer service. Did not work consistently. Charged for the entire year and then when cancelling they refuse to prorate any refund.
