    your Linksys device is sending to Quadro incorrect IP addresses in sip messages It`s a local IP address instead of global. Here is a part of incoming register message from your Lynksys pap2 device.

    Let`s try to change some configuration parameters on Linksys, especially on System page
    check the DNS configuration, on SIP page
    try to configure NAT settings, on Line page
    check the "Proxy and Registration" part parameters, are they configured properly.
