D-Link router and SIP issues

I just purchased a D-Link router and now I can’t dial out using SIP with either my X-lite soft phone or your auto dialer

Several of our customers have been having an issue with D-Link and other routers when using a VOIP Service via SIP with either a soft phone like X-lite or our Predictive Dialer (Agent Dialer). The fix is to open up port 3478 on your D-Link or other router. You will want to consult your user manual for your D-Link router or call their support for instructions on how to open ports on your router. Once you have done so, and assuming our SIP information is correct, our predictive dialer will operate flawlessly.
