Hi,

its easy to control Snom phones from outside by an http request http://username:password@192.168.0.1/command.htm?key=KEYEVENT

http://wiki.snom.com/FAQ/Can_I_control_my_snom_phone_remotely

also its easy to configure that an Snom phone send me an http request for example for an incomming call http://my.serverIP/pbx/snomcom.php?mac=$mac&actionid01

I would need an softphone for Linux and/or Mac with same or similar functionality.

best regads Thomas
