[. . . ] [. . . ] WB1051 creates a WiFi network and talks to WiFi or Dual mode phones on this network via SIP protocol. A SIP proxy server is embedded in WB1051 to allow WiFi handset to register and place/receive the intercom calls or PSTN calls. The WiFi coverage can also be increased by adding Tecom repeater WB1051R.
