Cisco Unified Wireless IP Phone

2 The phone displays the

configured for secure (encrypted) calls, but the icon does not mean that the other connected phone is also

protected.

3 A security tone plays if the call is connected to another protected phone, indicating that both ends of the

conversation are encrypted and protected. If the call is connected to a nonprotected phone, the secure tone

does not play.

Protected calling is supported for conversations between two phones. Some features, such as conference

Note

calls, shared lines, Extension Mobility, and Join Across Lines, are not available when protected calling

is configured.

Security Restrictions

When using a phone that is not configured for encryption, the user cannot barge into an encrypted call. When

barge fails in this case, a reorder (fast busy) tone plays on the barge initiator phone.

If the phone is configured for encryption, the user can barge into an authenticated or nonsecure call from the

encrypted phone. After the barge occurs, Cisco Unified Communications Manager classifies the call as

nonsecure.

If the phone is configured for encryption, the user can barge into an encrypted call, and the phone indicates

that the call is encrypted.

A user can barge into an authenticated call, even if the phone that is used to barge is nonsecure. The

authentication icon continues to display on the authenticated phones in the call, even if the initiator's phone

does not support security.

Deployment

When deploying a new IP telephony system, system administrators and network administrators must complete

several tasks to prepare the network for IP telephony service. For information and a checklist for setting up

and configuring a complete Cisco IP telephony network, see the "System Configuration Overview" chapter

in the Cisco Unified Communications Manager System Guide.

After you have set up the IP telephony system and configured system-wide features in Cisco Unified

Communications Manager Administration, you can add IP phones to the system. To add Cisco Wireless IP

Phones to the IP network, system administrators should conduct a site survey to determine strategic locations

for access points (APs) to ensure good wireless voice coverage. For detailed information about a voice over

WLAN deployment, see the Cisco Unified Wireless IP phone 7925 and 7926 Series Deployment Guide at
