• Cisco Unified Communications Manager Administration Guide, "Directory Number
Configuration" chapter
• Custom Phone Rings, on page 87
Ensures that held calls are not dropped by the gateway. The gateway checks the status of the
RTCP port to determine if a call is active or not. By keeping the phone port open, the gateway
will not end held calls.
Allows secure phones to place conference calls using a secured conference bridge. As new
participants are added by using Confrn, Join, cBarge softkeys or MeetMe conferencing, the
secure call icon displays as long as all participants use secure phones.
The Conference List displays the security level of each conference participant. Initiators can
remove nonsecure participants from the Conference List. Noninitiators can add or remove
conference participants if the Advanced Adhoc Conference Enabled parameter is set.
