Re: Don't hear ringing of called phone
Do you have a static IP addressed to the voip adapter. If you do; as an experiment, you can go into the router and turn ON the "DMZ" and point it to the static IP address of the voip adapter. This basically opens ALL PORTS and forwards them to the voip adapter. if this works, then you know it's a ports issue.
As for the firewall, you should turn OFF in the router: SPI. That is a firewall in the router. Also, there is a section called ALG. It lists programs like SIP. Turn off the ALG. If you really want a firewall for your computers you can install a software firewall like Zonealarm or Blackice on your computers and protect them locally. But SPI and ALG on in the router can definitely cause issues with voip. good luck.
