Resetting and Restarting Phones

This chapter describes how to reset or restart Cisco Unified IP phones that are connected to Cisco Unified Communications Manager Express (Cisco Unified CME).

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 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 10-1 .


NoteWhen 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.

Type of Reboot

Similar to power-off, power-on reboot.

Quick restart.

Phone Configurations

Downloads configurations for IP phones.

Downloads configurations for IP phones.

DHCP and TFTP

Contacts DHCP and TFTP servers for updated configuration information.

Note This command was introduced for SIP phones in Cisco CME 3.4.

Phones contact the TFTP server for updated configuration information and reregister without contacting the DHCP server.

Note This command was introduced for SIP phones in Cisco Unified CME 4.1.

Processing Time

Takes longer to process when updating multiple phones.

Faster processing for multiple phones.

When Required
  • Date and time settings
  • Network locale
  • Phone firmware
  • Source address
  • TFTP path
  • URL parameters
  • User locale
  • Voicemail access number

Can be used when updating the following:

  • Directory numbers
  • Phone buttons
  • Speed-dial numbers

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


NoteIf 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.
