I was with PhonePower for 5 years and recently "ported" to CallCentric. I am so glad I did! This summer, we 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 researched other Voip providers. Bottom line: I now have superb technical support, excellent custom features, and a much lower bill. Other than getting no calls for weeks, I was unhappy for a long time about other issues. #1: calls going through Nomorobo spam filtering rang once at home before Nomorobo killed spam. Calls that went through had the Callerid screwed up. The PP web interface was always very slow, clunky, and limited options, such as a small limit on blocked numbers, etc. I did not realize that other Voip providers now offer modern, fully customizable features, web gui and mobile apps. The PhonePower billing, rates, and policies are abominable compared to competitive providers. For example, when my credit card expired and got a new expiration date, as they do every few years, I don't think I ever received any notice. If they didn't email, they certainly knew the phone number to call me on! That was 9 months before recent issues and I did solve the billing problem. By the way, the online bills never show a name, jut an address. Which makes it more difficult to port a phone number out. Probably not by accident: "Hotel California" that is easy to get in and a huge pain to check out. Buyer beware. (I did get ported with the help of CallCentric support asking for a screen shot of the payment screen with my name on it). Five years ago PP was the best I could do after Verizon dumped us. Now, not so much.
I have been a customer since 2009. The service meets my needs with the main line and a cloned line, giving me the ability to have 2 calls simultaneously. From the beginning I have brought my own adapter (picking it from the list of supported devices). I recently replaced it and discovered that the automated provisioning scripts don't support the setup of the second line. That's okay -- I contacted PhonePower and they put me in touch with one of their technicians who was able to give me enough information so I could manually configure my adapter. Recently (August 2023), I noticed that my adapter showed everything was good but calls weren't coming through (going immediately to voicemail) and then one of the 2 lines became inactive. I contacted support via email and continued to work on the problem (I'm in IT so I don't mind digging into problems and stepping through a reconfiguration process). Using my notes from the manual setup, I got things working again. I also noticed that my firmware on my adapter was significantly out of date and updated it too. I had it fixed before customer support reached out to assist. Things ran well for a number of weeks and then suddenly calls were going directly to voicemail again. That's actually not a bad thing since PhonePower automatically sends a copy of the voice mail to my email. So, I typically screen my calls anyway. To fix it, I have simply unplugged my adapter for a few minutes and then everything works fine -- I can call the house phone from my mobile and everything rings through just fine. I don't know if this is a problem at PhonePower or with my adapter or perhaps my internet provider. I'll dig into it one of these days but it isn't on the top of my list to fix. The amount of spam calls has been reduced by use of NoMoRobo which Phone Power provides free along with good instructions to setup. So, overall, I'm happy with PhonePower. The sound of the calls is excellent; customer service has been responsive and helpful; and it does a pretty good job filtering out spam calls. Some reviewers have reported caller id not working in the past. All I can say is that it has always worked for me since 2009.
I regret to say that the experience with that company is just dreadful. I have purchased a number from them 02035155555 which costed £1000 if my memory serves me and I have been trying to port that number away from them for 10 months. They have flooded me with all sorts of technical details and admitted that they don't support Scenario 7 which is apparently the most common way of porting numbers in the UK. In one email they admit that Scenario 7 is less complicated than their preferred way of porting numbers and in another communication I have been informed that for technical and commercial reasons they don't support Scenario 7 porting. I have clearly stated that I would like to cover the costs if any and if they are reasonable, but obviously it's better for them to charge me monthly for all the incoming calls as opposed to cooperating in a process of number porting. In comparison, another number that was purchased from BT (01732463858) was ported to the new provider without any issues. They use obscure justification that they are not required to use Scenario 7 to avoid people leaving their network with their own property ... I strongly suggest avoiding that company at all cost. *********** Response from SureVoIP *********** Dear Paul, Thank you for leaving a public review of your experiences with SureVoIP here and on our Facebook page. To say I'm surprised is an understatement. Number porting is driven by the **Gaining Communications Provider (GCP)**, i.e. the company you move your number to. SureVoIP in this case are the Losing Communications Provider (LCP). We worked with your GCP, which we will not name because you have not, and explained what they needed to do. If you recall, I even sat on a conference call with them, you and your solicitor explaining what they needed to do as they were doing it all wrong and you were getting extremely frustrated. I also gave everyone the call recordings of that call. They came back to you and basically said they weren't interested? I then took the extremely rare path of approaching one of the carriers they use to set up a porting agreement with them for you. That process is not complete yet, that's why I was surprised that you post these negative reviews of SureVoIP. In all honesty, I couldn't have done more for you. With regards Scenario 7. This is not a UK standard and is a managed service from the BT Wholesale IP Exchange product for those that wish to use it. Using it is a technical and commercial decision that we have not opted for. It's not just a case of paying for a one of number port as you think. Forcing SureVoIP to use it is like telling an IT company to only sell Dell equipment. A Communications Provider is free to work with the LCP or GCP to agree a commercial and technical number porting method. For a list of those operators we have porting agreements with, please see https://www.surevoip.co.uk/support/wiki/number_porting SureVoIP are one of few that have the ITSPA Quality Mark in the UK. ITSPA review all of above and are very friendly if you approach them with concerns or wish to seek advice. I built SureVoIP by hand, from scratch with no investment and when I see reviews like this I take it to heart as I strive to please everyone, which I know is now not possible. Thank you, Gavin
