Release 12.2(11)YT1:

Cisco IOS Release 12.2(11)YT1 introduces improvements to phone rebooting commands and an updated 
script for the H.450 transfer and forward application.

After you update information for a phone that is associated with a Cisco IOS Telephony Service (ITS) 
router, the phone must be rebooted for the new information to take effect. In Cisco IOS 
Release 12.2(11)YT1, the reset command has been modified to allow the sequential reboot of the ITS 
phones. Using a sequential reboot minimizes the risk of conflict which can occur when multiple phones 
attempt to access changed ITS configuration information through TFTP. In addition, the restart 
command has been added to support quick phone rebooting for use when only the line and speed-dial 
configuration for a phone is changed.

The tool command language (TCL) script that controls H.450 applications has been updated in the 
current release and is named app-h450-transfer.2.0.0.2.tcl. You can continue to use the previous script, 
called app-h450-transfer.2.0.0.1.tcl, with Cisco IOS Release 12.2(11)YT1, but you cannot use the new 
app-h450-transfer.2.0.0.2.tcl script with a release of Cisco IOS software that is earlier than Cisco IOS 
Release 12.2(11)YT1.
