Hi!
Using MSPL I'm proxying sip requests to my UCMA application endpoint to do call control. I am however experiencing some difficulties when I try to forward a Lync call from a Lync client. The application endpoint is receiving the call, but when the call is attempted forwarded, the Lync client just keeps ringing and the recipient the call was forwarded to never receives the call. I've tried logging on the front end server using Lync Server 2013 Logging Tool, but there are no logs regarding the call.
If I make an enterprise call (e.g. from a physical phone) the call gets forwarded properly and the recipient receives it.
Thanks in advance!
