I used to write a variety of articles (https://tsoorad.blogspot.com) on technical issues with a smattering of other interests. I have a variety of certifications dating back to Novell CNE and working up through the Microsoft MCP stack to MCITP multiple times. FWIW, I am on my third career - ex-USMC, retired US Army.

SfB Call Drops–Actiance Vantage

If you are running Actiance Vantage on Lync 2013 and have it working just fine, and are planning on upgrading your environment to SfB…

The Issue

Lync 2013 environment totally replaced by SfB.  Everything works great. So we then installed Actiance Vantage for compliance requirements.

SfB calls work pretty well for the most part; but there are random drops, disconnects, and other flaky problems.  SfB, PBX (Avaya 6.x in our case) and network troubleshooting showed nothing.  Digging deeper, there were trace logs that showed the SfB FE dropping calls for no apparent reason.  Digging deeper with Microsoft CSS revealed that the call disconnects were coming from the Vantage agent.

It turns out that the Vantage agent installer for the SfB servers uses Lync 2013 SDK components (installed onto the SfB server by the Vantage agent install process). Apparently there is some incompatibilities with SfB and the Lync 2013 SDK components as installed by the Vantage installer.

Resolution

There is a fix that involves new Vantage agent installs.  I will assume that you must contact Actiance to help resolve this issue.

YMMV.
