Information About Resetting and Restarting Phones
Before resetting and restarting IP phones in Cisco Unified CME, you should understand the following concept:
•
Differences between Resetting and Restarting IP Phones
•
Cisco Unified CME TAPI Enhancement
Differences between Resetting and Restarting IP Phones
Cisco Unified IP phones must be rebooted after configuration changes in order for the changes to be effective. Configurations for phones in Cisco Unified CME are downloaded when a phone is rebooted or reset. You can reboot a single phone or you can reboot all phones in a Cisco Unified CME system. The differences between reboot types are summarized in Table 29.
Note
When rebooting multiple IP phones, it is possible for a conflict to occur if too many phones attempt to access changed Cisco Unified CME configuration information via TFTP simultaneously.
Table 29 reset and restart Command Differences
|
reset Command
|

|
Type of Reboot
|
Similar to power-off, power-on reboot.
|
Quick restart.
|

Cisco Unified CME TAPI Enhancement
Before Cisco Unified CME 7.0(1), the only method to clear a session between a Microsoft Windows Workstation and an SCCP phone that was out-of-sync was to reboot the router. In Cisco Unified CME 7.0(1) and later versions, you can clear a Telephony Application Programming Interface (TAPI) session that is in a frozen state or out of synchronization by using a Cisco IOS software command. For configuration information, see the"SCCP: Resetting a Session Between a TAPI Application and an SCCP Phone" section.
This enhancement also automatically handles ephone-TAPI registration error conditions. No additional configuration is required for this new feature.
How to Reset and Restart Phones
Note
If phones are not yet plugged in, resetting or restarting phones is not necessary. Instead, connect your IP phones to your network to boot the phone and download the required configuration files.
