I am planning to make a soft phone JQuery plug-in with the new Skype web-SDK. It is still unclear to me if the web-sdk depends on UCWA or that it can be used with the classic UCMA as well, and does it require Office365 for on-premise UCMA / UCWA machines like a cloud hosted instance.
Also what is the current availability of UCWA?
Thanks in advance.
Has been recently announced, during Build 2016 conference, that UCWA as well as Skype Web SDK is now available also for Office 365 customers.
UCMA is still only available to customers with on-premises Lync 2013 / SfB installation
