Lync Server Limitations in this Deployment
Microsoft Lync Server 2010
The Microsoft Interoperability option key must be installed to enable encrypted calls to and from Microsoft Lync
2010 Server (for both native SIP calls and calls interworked from H.323). It is also required by the B2BUA when
establishing ICE calls to Lync 2010 clients.

establishing ICE calls to Lync 2010 clients.
The B2BUA can use the Cisco AM GW to transcode between standard codecs (such as H.264) and Microsoft RT
Video and RT Audio to allow high definition calls between Microsoft Lync 2010 clients and Cisco endpoints.

Screen sharing from Lync clients toward video network endpoints is not supported on Lync Server 2010.
Microsoft Lync Server 2013
The B2BUA provides interworking between standard H.264 AVC and Lync 2013's H.264UC SVC codec. You can still
configure the B2BUA to use Cisco AM GW transcoders with Lync 2013, but it is not necessary and we recommend
that they are not deployed with Lync 2013.
