Hello, I recently got vonage and noticed that my D12 receivers are unable to successfully connect with Directv. In the calls log I see that the receiver is indeed making the daily calls to 2 toll free numbers, however when I called DTV tech support they are saying that the calls arn't succesful. They walked my throught the process of adding *99 Prefix in the receivers but nothing seems to change. I contacted vonage which ran tests to diagnos call quality and other stuff but no luck. The techs at vonage even have me disable call waiting but to no avail. I did a thorough research online and saw many posts with different sol.utions but all those seems to be directed at tivos/dvrs. I tried them however with no luck. Can anyone help? PS I tried several variations of the dial out prfixes which includes: *99 *99.. ..*99 ,*99, and many others were tried.
