Any one idea why VOIP is not registering (it fails with both Cisco pap2 & in x-lite software) in hathway broadband though they claim no ports are blocked & same configuration voip works in VSNL broadband. I did test with testyourvoip.com with boston location it fails stating ports may have be blocked (same result when asked to do this test at their DC), suprisingly test for london passed. Tech Support is real dump and still claim all ports are opened. Then why I'm facing this problem? anyone was success with vonage or other voip?
