Controlling CS500 / C054A
We are trying to support the CS500 headset for an emergency services solution. Our configuration is: CS500 - C054A - APU-72 (or APU-75) They used the headset on normal desktop phones and would like to keep them with the shiny touchscreen Windows/Linux-based solution. The voice works ok, but we would like more control: - how to control if the key on the headset has been pressed? - is it possible to force hook on/off from the PC side? Goran

Hi,<br /> <br /> Thanks for your question. If you want programatic control from the PC side you will need to use the APU-75.<br /> The APU-75 is listed as a supported product for our Plantronics Hub software solution: <a href="http://www.plantronics.com/uk/product/plantronics-hub-desktop">http://www.plantronics.com/uk/product/plantronics-hub-desktop</a><br /> This is the same as our <a href="/sdks">SDK </a>and <a href="/article/plantronics-sdk-3x-deployment-options">minimal runtime installers</a>.<br /> <br /> The API you would use to force the device off-hook would probably be:<br /> IDevice.HostCommand.AudioState = AudioState_MonoOn&nbsp;&nbsp; -- this will go off hook, i.e. activate<br /> IDevice.HostCommand.AudioState = AudioState_MonoOff&nbsp;&nbsp; -- this will go back on hook<br /> <br /> For more details take a look at our <a href="/api-specification-doc">API reference</a>.<br /> <br /> Let me know if you need more help.<br /> <br /> Thanks,<br /> Lewis.<br /> <br /> <br /> &nbsp;

<p>Hi,<br /> <br /> I&#39;ve got an APU-75. In order to be as open as possible we decided to go with the REST API.<br /> So, we sent:&nbsp;<br /> <span>&nbsp; &nbsp; &nbsp; &nbsp;</span><span>http://localhost:32017/Spokes/DeviceServices/AudioState?state=1</span></p> <p><br /> But, we got:<br /> <span>&nbsp; &nbsp; &nbsp; &nbsp;</span><span>Executing Audio State command: device not supported</span><br /> <br /> Not sure if this is the right command as there is no relation to a specific device, session or plugin.<br /> <br /> I also tried to register an incoming call, but in such case the PLTHub.exe crashes!<br /> <br /> It is interesting that Skype handles the hook even on APU-72.</p>

Hi,<br /> I will take a look into this in more detail tomorrow. It is possible this device uses a different interface in the API...<br /> Thanks,<br /> Lewis.

Hi Lewis,<br /> <br /> I took one of the REST samples and figured out the correct parameters.<br /> I&#39;ve used numerical 0,1,... instead of MonoOn or ToHandset. This was not too obvious enough in the docs or I just skipped that part.<br /> Anyway, it is still disturbing that PLTHub crashes in case of wrong parameters.<br /> <br /> BTW: Why my entries forget all formatting and newlines?

Hi Goran,<br /> <br /> I am glad you made progress.<br /> <br /> I have tested the REST calls with APU-75 using this hosted demo (work in progress): <a href="http://developer.plantronics.com/plantronics-rest-demo" target="_blank">http://developer.plantronics.com/plantronics-rest-demo </a><br /> <br /> If you try this with Firefox you can use the Developer Tools to see exactly what parameters it is sending, as the following screenshot shows:<br /> <br /> E.g. for outgoing call: http://127.0.0.1:32017/Spokes/CallServices/OutgoingCall?name=Hello World JavaScript Plugin&amp;callID={&quot;Id&quot;:&quot;1&quot;}&amp;contact={}&amp;route=ToHeadset<br /> <br /> <a href="http://developer.plantronics.com/sites/default/files/APU-75%20rest%20illustration_0.png">Click here to see full image</a><br /> <br /> [[{"fid":"93","view_mode":"default","type":"media","attributes":{"height":"990","width":"1771","class":"media-element file-default"}}]] <br /> Cheers,<br /> Lewis.<br /> &nbsp;
