Microsoft Lync and Skype for Business have a rich set of .NET APIs which make it easy to extend the platform and integrate it with other applications. This blog helps explain how to use those APIs.

Security exceptions with managed SIP applications

Posted: March 27th, 2012 | Author: | Filed under: Lync Development | Tags: , | No Comments »

Applications built using the Managed SIP Application API can be a bit tricky to troubleshoot. If your managed SIP application fails on startup with an UnauthorizedException or a SecurityException, make sure that the user account that the application is running under is a member of both the RTCComponentUniversalServices domain group and the RTC Server Applications local group (on the Lync Front End Server). If you’re running it as a console application, you’ll need to make sure your own user account is in both groups; if it’s a Windows service, make sure the service is using a domain account that belongs to the two groups. This should eliminate the exception.
