    Roy,

    We'd need more information, but it sounds like it could be a router issue. If your router has SIP ALG (application-level gateway) enabled, it's likely blocking VoIP service. We recommend disabling SIP ALG as a matter of course. For more information on it, as well as how to disable it in certain types of routers, check out http://www.voip-info.org/wiki/view/Routers+SIP+ALG
