Grandstream 486 VoIP settings & configuration Guide
Grandstream 486 is a router and ATA adaptor with a WAN, LAN interface, PSTN and POTS line enabling you to use a traditional phone or fax machine as a SIP enabled IP device. The PSTN line (FXO) is not usable via SIP. It only used as a fallback for power failure. This device includes a NAT Router for your home or small office.

If you get one-way audio, or cannot get a dial tone or cannot make/receive calls with your VoIP device, you are probably behind firewall. Your router's firewall (also known as NAT) is blocking certain operations of the VoIP telephone adapter or some of the settings of the adapter is not entered correctly.
