I put this booster in line with my MagicJackGo. All four handsets are now working (both ringing and voice) through my home wiring. CallerID seems to be working as well.

It was the easiest device to hook up. I have
3 old dial wall phones and 6 "modern" touch
tone phones. All my old dial phones ring loud and clear now. A good investment.

Blazing fast shipping and great product. Highly recommended seller!

I have Magicjack plus and could only ring one phone. With the Viking ring booster I now ring all six of my phones loud and clear. Works great and simple to hook up. Highly recommended.

I have VOIP phone service through AT&T U-verse and had been having intermittant problems with my phones not ringing. Sometimes the caller ID information would not display.

My home has the equivalent of 7 telephones, but the recommended maximum is no more than 5. I suspect that the extra phones were loading down AT&T's residential gateway (i.e., modem/phone controller).

After installing the Viking RG-10A ring booster, the intermittant problems stopped. The phones now ring and display caller ID consistently.

I can hear the mechanical clicking noise of a relay inside the Viking RG-10A and I hope that the relay continues reliable operation for many years.

The bright red LED ring and off-hook indicators work well and look neat.

Have not yet connected my RG-10A, but your ordering process is great and simple, the product arrived sooner than I expected, the packaging was very professional, and the enclosed documentation was complete; the "logistics" from Viking certainly met my expectations. I expect no technical problems with the device.

I have VOip and have 5 phones and 2 of them are Rotary. The one rotary phone would not ring loud until I bought the Viking Ring Booster. It works and is extremely easy to setup.

Author: freddy Y    02/23/2011
This little box rang my 1956 Bell telephone right off the hook using a NetTalk voip system which was impossible before... so it definitely does what it was designed to do....I love the sound of those old Bell phones.....

I have 10 phones and devices in my house. Just set up Lingo VOIP phone service. The RG-10A is providing signal, Ring and power to all of theses phones. Working great. Twister fully met my expectations.

The Viking RG-10A worked as advertised. I was impressed with the additional ability to boost the talk battery voltage.

Author: Barry    05/14/2010
The Ring Booster is working great. All 12 phones in my house now ring off of the Magic Jack.

Author: Charles    10/01/2009
It worked right out of the box eliminating the very poor ring quality on the five phone in our house.

I purchased my Viking RG-10A ring booster from The Twister Group in March of 2008 to use with my Earthlink VOIP service. I used it without any problem until I cancelled my Earthlink phone service along with my Earthlink DSL service a couple of months ago. I have been using the RG-10A since then with the ATA that I now use with my new Voip provider, PhonePower. I have 12 old Western Electric Telephones from the 50s, 60s, & 70s all over my house that ring as loud as they did when they were brand new. My Viking RG-10A has been running around the clock 24/7 powering the ringers of 12 real phones for over 6 years now and has not missed a beat. The Viking RG-10A is a great product that I highly recommend to anyone who needs to add some extra phones to their VOIP service and needs more ringing power than their ATA device can provide.
By the way, I purchased my Viking RG-10A from The Twister Group in 2008 because they were selling them for the best price that I could find online at the time. Mine arrived within 3 days after I placed my order in March of 2008. If you need a RG-10A look no further. Buy it from The Twister Group and you wont go wrong.
