New and Changed Information
This section contains these topics:
•
Connection Monitor
Connection Monitor is a feature that enables an administrator to change the amount of time that a link between a phone, which is registered with an SRST due to a failover, and a Cisco Unified Communications Manager must remain stable (with no link-flapping) before the phone falls back from SRST to the Cisco Unified Communications Manager.
The connection monitor duration is defined in the Cisco Unified Communications Manager Administration under System > Device Pool, and applies to all IP phones in a specific device pool. The default value is 120 seconds.
Link Layer Discovery Protocol Media Endpoint Devices (LLDP-MED)
Link Layer Discovery Protocol Media Endpoint Devices (LLDP-MED) is a standardized networking protocol similar to Cisco Discovery Protocol (CDP). Cisco supports LLDP-MED, so customers can use third-party devices and retain the benefits of CDP functionality.

Cisco Catalyst Port Security and LLDP-MED
Cisco Unified IP Phone firmware release 8.3(3) and later, provides support for the LLDP-MED Link Layer protocol. LLDP is a protocol similar to CDP and used for device discovery between a LAN switch and an endpoint. Some Catalyst switches running IOS earlier than 12.2(44)SE, may not support LLDP and indicate that an extra device has been connected to the switch port.
If the Catalyst switch is using Port Security to count the number of devices connected, the appearance of an LLDP packet may cause the port count to increase, and cause the switch to disable the port. Please verify that your Catalyst switch supports LLDP, or increase the port count, before deploying this firmware.
TabSync Does Not Connect to Cisco Unified Communications Manager
When you use the TabSync tool to synchronize the Windows Address Book, TabSync does not connect and an error message displays.
TabSync does not work with Cisco Unified Communications Manager release 6.0(1) and later. For more information, refer to CSCsk58101.
Cisco Unified IP Phone Displays XML Error with Extension Mobility
When you use firmware release 8.3(3) with Cisco Unified Communications Manager 6.x, you must use Cisco Unified Communications Manager engineering special release. If this is not used, you will receive an XML parse error when you login or logout of a Cisco Unified IP Phone. Contact your Cisco support representative to obtain the engineering special software. For more information, refer to CSCsj79645.
Daisy Chaining Cisco Unified IP Phones
Cisco does not support connecting an IP phone to another IP phone through the PC port. Each IP phone should directly connect to a switch port. If phones are connected together in a line (daisy chaining by using the PC port), the phones will not work.
