I've been a customer of OOMA for almost two years and my experience has been very good to excellent. I've received excellent call quality and customer service/support. I've had only one major issue, the replacement of my Telo unit (under extended warranty) after about 18 months, which was handled expeditiously by OOMA Customer Support. Additionally, I've enjoyed a savings of over $60.00 per month over my prior telephone service provider which means that my payback for the purchase of the OOMA Telo and Handset was about five months. Its all been gravy since!
To the subject of this message, many new OOMA Users are able to simply follow the in-box instructions and successfully install and register their units. However, in this forum I see many forum visitors struggling with their VOIP installations. Many of the questions are related to Customers difficulties integrating the OOMA products into their residential telephone wiring setups.
There are several experienced Users in this forum who persistently and tenaciously help answer Customer questions and there is a wealth of information scattered througout these forum topics. But when it comes to integrating VOIP into residential telephone wiring setups many of the forum topics end up being long exchanges of tips on wiring approaches with exchanges of photos of telephone company demarcation boxes/points and novice users really struggling to grasp the concepts.
In the interest of helping new Users with these struggles of integrating VOIP into their residential telephone wiring setups, I've found the following documentation to be very helpful. It brings together in one place most of the information Users will need to deal with wiring, testing, troubleshooting, faxing, alarm systems, satellite TV and other dial-up home services.
Although at an initial read the documentation might seem a bit daunting to a novice non-technical User, in general the author has explained much of the information in terms most Users will be able to understand after a couple of reads. I hope its helpful!
