Mute and unmute the device

Hi,

I am using Plantronics Rest SDK in a sample application.I got stuck in a problem.

I want to mute and unmute the plantronics device through user interface.

Is it possible to mute and unmute device using Device services(by attaching a session)?As far, I did not get any REST call for the same purpose.

I am able to perform mute , unmute operation by using Session Manager Services(by registering plugin).But the problem is that Session services and plugin services are not working simutaneously.Is it the desired behaviour or something went wrong with simulator.

Query: How can I get running both the services simultaneouly so that I can send commands and listen notifications from device?

Am I missing out something?

Your quick response is highly appreciated.

Thanks!!
