The Linksys PAP2 is an analog telephony adapter (commonly referred to as ATA), which allows for the connection of one or two “normal” telephones to a VoIP provider using the Session Initiation Protocol (SIP) protocol. The SIP traffic is sent through the PAP2's Ethernet port. The device is one of Linksys's first entries into the Consumer / SOHO Voice over IP devices market.
The PAP2 is based on the Sipura SPA-2000 ATA design. The device is powered by an ESS Visba 3 (ES3890F) chipset. It utilizes a Realtek RTL8019AS 10BaseT Ethernet controller, which provides a 10 Mbit/s/ half duplex connection to a LAN.
The units have 2 RJ11 sockets, which allows for two "lines" (each with their own unique SIP registrar / username etc, for truly separate configuration).
