System information

New feature descriptions TC6.2.0

Call preservation

If the TelePresence endpoint loses its connection to the primary CUCM, the call is preserved. This

provides greater resiliency and a better user experience. All actions (e.g. presentation, hold) on the

touch panel will be greyed out except for “Hang Up” since call control is lost (connection to the

CUCM). The next call will be handled by the secondary CUCM and all call features will be available.

When the primary CUCM is back online, the endpoint will automatically register with the primary

CUCM and de-register to the secondary CUCM.

Improved provisioning from CUCM

Several provisioning parameters have been added to TC6.2. For a detailed description please see

“Administering TC endpoints on CUCM guide” for TC6.2.

Encrypted configuration from CUCM

TelePresence endpoints can be fully and securely provisioned from Cisco Unified CM with a simplified

deployment. When the TelePresence endpoint has been setup with a secure connection (encrypted

security profile) in the CUCM, the provisioning data from the CUCM to the endpoint is encrypted. The

data will be transmitted over HTTPS. TC endpoints will only read admin password if the endpoint has

been set up with an encrypted security profile. The password cannot be empty and the user name

must be admin.

Support for auto discovery of the CUCM

The TelePresence endpoints now have support for auto discovery of the CUCM through option 150

without using CDP/VLAN. After a factory reset the endpoint will automatically register if the network

provides a CUCM in DHCP Option 150. This is achieved by altering the default value for

xConfiguration Network 1 DHCP RequestTFTPServerAddress to On (previously Off).

ICE support

ICE provides the optimal media path by sending peer to peer when possible:

• Enables cloud scenarios

Reduces bandwidth cost: No need to traverse cloud or enterprise servers

• Reduces traversal load of VCS

• Standardized IPv4/IPv6 dual stack solution

• Separates signaling and media

A signaling path must exist for ICE to work

Pre-requisites and requirements:

Both endpoints in the call need to be ICE enabled and configured with a valid TURN server and

credentials to allocate a relay port. If TURN connection is missing, only the host port is offered.
