After applying Office Communications Server 2007 R2 July 2010 cumulative updates to Office Communications Server 2007 R2 Enterprise Edition or Standard Edition servers the Response Group Service will’ve to be restarted when:
- New Response Group objects have been created
- Existing Response Group objects have been updated
- A call is routed to new or updated Response Group objects
In the scenarios above a incoming call to a Response Group Agent from OCS 2007 R2 Conferencing Service could fail.
“To workaround, restart RGS on affected OCS2007 R2 EE or SE front end servers. Note: Microsoft will address this issue by with Sep 2010 update for OCS2007 R2,” explainded Micrsoft in KB2401878.
