In all 3 of your experiments, it goes to voicemail. Forget if you hear ringing or not. Can you call the other end. Are you saying that with callcentric, if you call the at*t wireless cell phone, it DOES RING the actual cell phone? Or do you simply hear a ringing in the headset? As spaeth was saying, it doesn't matter what you hear. The ONLY REASON phone companie put a dial tone on the phone, is to make you think the phone works. As you know, there's no dial tone on a cell phone.

Now; if you're saying that you can call the AT&T cell phone from call centric and it actually rings the cell phone and it can answer your call; then yes, there is an issue. You say it HAS TO BE voipo's end. That's not necessarily true. However; for the average customer, who doesn't know how voip works, all they care about is THEIR END; meaning their phone and internet; and VOIPO's end; meaning everything else. There's a lot more in between. But for the customer, they shouldn't care about thatl.

So; IF you can call a specific number with callcentric and the other end rings, and they can answer it; but you CAN'T when using VoipO, then open a ticket with voipo. Give them the number you are trying to call and that it won't connect. I have that problem at work ALL THE TIME. I will have a customer call up and say they can't call a specific number. Find out that a new prefix has been added in a state or country and my PBX isn't programmed for that area code or prefix. I add the number, and all is good.

Another test is to see if you can call ANOTHER 661 area code AND PREFIX phone that is similar to the one you can't connect to. Life is simple. We make it harder than it really is. But open a ticket with voipo, once you know what the true problem is, and they can definitely help you. If you don't have all the facts and are assuming certain things work or don't work, then it could take voipo a long time to figure out what the problem is. Remember; you are on Voip, and you're trying to connect to cell phone and land lines. That's 3 different technologies, with 3 different providers. What you describe is not unusual and happens every day; even with cell phones and land lines. Landlines have over 100 years of experience making a process to catch these issues. Cellular and voip have to sometimes catch these issues one at a time.
