Hello,

Please check B2BUA and neighbor zone status. Read following document and go through all steps:

- B2BUA, pages 34-39

- Lync Server configuration, pages 31-33

Is the B2BUA a must option, if deploye the intergration of VCS and Lync.

For VCS X5.x, X6.x and X7.x can be used non-B2BUA mode (OCS Relay)

For VCS X7.0 or later can be used B2BUA mode

Please be aware

Features and capabilities with different versions of software

The versions of software (Cisco VCS X4, X5, X6, X7 and OCS R2, Lync 2010 / standard, enterprise) affect the capabilities of the deployed system.

- Cisco VCS can interoperate with both OCS 2007 R2 Standard and Enterprise edition.

- Version X6.1 or later is required to support Lync Standard edition and Lync Enterprise edition.

- Version X7.0 or later is required to support VCS B2BUA

- Beyond X7.x it is expected that OCS Relay will no longer be available
