Audiocodes and Lync, unanswered call dropped after 30 seconds

SBC and Lync SBA configured according  to the documentation, but calls are are getting dropped after 30 seconds.  RTCP setting seems to be Generate Always, but we do not see any RTP UDP streams being sent by SBC to Lync.

I will try to disable RTCPActiveCalls in Lync and see it that helps.
