We tried to use this system for about a year and it was an absolute nightmare. Dropped calls, phones crashing in the middle of a conference call, FXO sound quality was a complete joke, faxing never worked despite using supposedly supported interop scenarios and T.38 set up correctly, and numerous features that were supposedly included with our system were showing as blocked by the license. When we complained to PBXnSIP (now Snom) and tried to get tech support, they complained to us that we were a direct customer and that was not how they did business, we should instead contact the reseller for tech support. The reseller told us that their only channel of support with PBXnSIP was via the online support forums. It seems that PBXnSIP really went out of their way to try to avoid providing tech support. PBXnSIP was a total waste of time and money and caused a great deal of frustration. We switched to Cisco Unified Communications Manager Express a while ago and couldn't be happier, unlike PBXnSIP it works reliably as advertised, interop with other products is fantastic. Unlike the Snom phones, the sound quality is actually good too.
We had high hopes to save money with them but its been short of a nightmare. We have swithed to a new company and haven't had any problems like with pbxnsip.
I rarely give 5 stars to anyone, but CallCentric earned them. We were using PhonePower (1 or 2 stars, arrgh!) and learned that our home phone had been ringing busy for over a week and important calls had not gotten through. After much hassle with PP, I found CallCentric and got a new number. Getting setup was easy and the online customer support was prompt, professional, extremely competent, and patient working with me on customizing my account. My original home number (for 20+ years) was ported from PhonePower to CallCentric with assistance from CC support. Here are the benefits to having "unbundled" services from Callcentric: #1: My configuration now is: calls to the orig number are forwarded to the new CC number. That is Inbound only, $1.95/month, not calling out on it. New number is both In and Out, a "normal" phone number. We also have a number used by an alarm system, Outbound only, saving more than $29/month with most Voip servcies. #2: CallCentric allows me to customize features that most Voip providers do not. We have a new CallerID of our choosing; SMS texts can go straight through, as expected, forwarded to a mobile, or emailed -- our choice. When calls come in, they are filtered to deal with spam and then there are special "Call Treatments". Calls from MY doctor's office rings on the home landline AND simultaneously on MY personal mobile. Calls from my wife's family can go straight to her mobile and even not ring on the home phones. There is an option for "hunting": if a phone doesn't answer, the call goes to a second number (mobile) or a third, ... And the caller does not know about the treatments. A call to our original number is answered (or sent to voicemail, etc.) and they do not know what phone we answer. Might be away from the house on a mobile, the caller does not know that. Get a DID number for a family member and customize call treatments for them. Bottom-line: CallCentric has the highest quality network I have ever experienced, superb technical support, excellent custom features, and unbundled services so I pay only for what I need. I am paying less than 1/5th of what I would (did, sigh) pay for the same three numbers at PhonePower, Verizon, and many others. Reviews from 10 years ago may read differently, but CallCentric is world-class these days.
Callcentric offers the worst customer service imaginable. Listen to all the reviews. They offer only ticket based support for any issue you have. So if you're having technical/billing issues even emergency ones which are breaking your service, you will have to open a ticket and wait. Furthermore, based on my experience, much like other people's below, the technical support person will disclaim any responsibility even if it's clear he could help. Do you really want to trust your phone service to a company that offers only support tickets for help? Think about it ...
