Help to get simple Events

Hi all,

I have developed a softphone and I´m using the example "SpokesSDKCOMSample" in order to program a module that only gets the events "Buttonpressed" from the Headset Plantronics CS60

The problem is, the button enables and disables the Audio State of the headset and I would like to get only the event "Buttonpressed".

Can I disable this feature in order to get only a simple event? and How can I do it?

Thank you in advance

Francisco
