The Linksys PAP2T-NA Internet Phone Adapter enables high-quality feature-rich VoIP (Voice over IP) service through your broadband Internet connection. Just plug it into your home router or gateway and use the two standard telephone ports to connect analog phones or fax machines. Each phone port operates independently, with separate phone service and phone numbers, like having two telephone lines. With the Linksys PAP2T-NA you'll get clear reception and reliable fax connections, even while using the Internet at the same time.

The Grandstream 502 is compatible with SIP 2.0 and includes dual FXS and dual RJ45 Ethernet ports. Integrated into the data side of the device is a NAT router and room for two SIP account profiles. The device supports Universal Plug-in-Play and traditional and advanced telephony features.
