It is a small SOHO router from LinkSys that has 2 FXS ports, an ethernet 
switch with 4 ports and a wireless interface. It came with Linux 2.6.14 
installed and a VOIP application which uses 40% CPU when a call is up. 
I'm trying to replace this VOIP application with asterisk configured as 
TA (basically asterisk is a VOIP phone). I think the phone hardware is 
based on legarity slics.
