C100S - Skype Desktop API will no longer be active. Any replacement?


I've got e-mail, that Skype decided to terminate Desktop API {see forwarded mail bellow}.

We are using many Polycom Communicator C100S, which rely on connection to Skype API.
Could you answer me, please, what will be replacement for Communicator software to keep button / LED functionality?

Thank you forward for your replay.

Subject: Important information regarding the Skype Desktop API


I am writing to inform you that due to some changes we are making to improve the overall Skype Experience, the Desktop API will cease to function correctly from September 2013 and we have made the decision to de-commission it.


As you may know, Skype has been investing in technology improvements, which will significantly benefit Skype users across all platforms, especially Mobile devices (see "Skype's Mobile Future"). These changes will significantly improve the speed of delivery of calls and messages, whilst retaining excellent battery life. In addition, as more people are using Skype on more devices, we are also working hard to create a more familiar and consistent Skype experience across all of the major platforms (see "Skype passes 100M Android Installs and Launches Redesigned 4.0").


As a consequence of this, we have decided to retire our Desktop APIs. These APIs were originally created in 2004 and do not support mobile application development. Going forward, developers will be able to write applications, which use features of Skype across all the major platforms, through the use of Skype URIs. We believe this will allow developers to create innovative mobile, web and desktop solutions, while retaining a familiar and consistent Skype experience across devices.

Although we will continue to support the Desktop API for the rest of 2013, in September the App Directory will close, chat functionality through the API will stop working and we will begin notifying users with messaging in Skype for Desktop. As a result, we wanted to give you notice now so you have the opportunity to modify your application in response to these changes.


I want to personally thank you for your investment in Skype throughout the years. This decision was not made lightly. Going forward, we hope you will consider the use of URIs as a way of developing innovative Skype powered solutions. If you have any questions or comments about the changes, please contact us at . We’ll do our best to address them in a timely fashion.

Hello Petr,

welcome to the Polycom Community.

Skype / Microsoft develop the Skype application.


Polycom manufactures the C100S that works in conjunction with their application.


If Skype / Microsoft decide to remove the API support you can only work around this by not upgrading to their future software in order to keep that functionality.


For any further follow ups you should keep communication with Skype / Microsoft.


The C100S was launched back in 2003 so the product has been going for some time now.


Polycom plans to release a new device called SoundStation connect and details can already be found => here <=
