Notes
Conference is the only feature supported
due to other feature limitations.
Voicemail will not be synchronized with
other users in the Cisco Unified
Communications Manager cluster.

Call Forward All settings are not preserved
on failover to SRST from the Cisco Unified
Communications Manager, or from SRST

Any original Call Forward All still active
on the Communications Manager should
be indicated when the device reconnects to
the Communications Manager after failover.
The iDivert softkey does not display.
Lines are supported but cannot be shared.
The Park softkey does not display.
User sees the message That feature
is not currently available.
