Ideal Telecom vs CallCentric

I wanted to totally rid our lives of att: directv, att landline, cell phone service. My Son is an IT professional and he suggested signing up with CallCentric. I feel I'm medium advanced when it comes to technology. It was not a simple procedure to get a VoIP adapter, sign up for the service, and then all is going to work properly. Insure when you start the process, "don't disconnect" your present land-line service until all is completely done. With CallCentric you can "PORT" (keep your existing phone number) which I did. But it takes many days for the number to port. I disconnected my att service the day I signed up with CallCentric and sent the port request. Big Mistake! I was without land-line telephone service for I think 2 weeks. One of the items that's very confusing with CallCentric is that you have to purchase 2 services: You must pay for one service to receive inbound calls, and purchase another service to place calls. Don't know why CallCentric would require this, but that's the way it is. I purchased a Grandstream GS-HT802 telephone adapter off Amazon for $40.00. I'm not advocating this particular adapter, but it's working well for us. It's simple to hook everything up. You run a wire from the telephone adapter to your internet router, plug in your present phone to the adapter, plug the adapter into an electrical outlet, and you're good to go. I have 3 cordless telephones. I plugged one of the phones into the adapter and placed the other 2 phones in convenient locations. Once the number ported and I figured out that I had to purchase 2 services: Inbound and outbound, everything is working perfectly! I purchased the DID - Personal Unlimited option for $6.00 per month for inbound calls, and the North America 500 for $7.00 per month for outbound calls. So around $13,00 monthly. Believe I was paying att $45.00 per month for land-line service. With CallCentric you get a bunch of free stuff: anonymous call blocking; voice mail; call treatments. Remember: When you place any call you must press the number 1 first, along with the other 7 digits. The service does not recognize 7 number dialing. Overall, I'm very pleased with CallCentric and highly recommend the service.
