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

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 13.

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 13 reset and restart Command Differences
	reset Command	restart Command
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	•Directory numbers •Phone buttons •Speed-dial numbers

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.

This sections contains the following tasks:

• SCCP: Using the reset Command (Required)

• SCCP: Using the restart Command (Required)

• SIP: Using the reset Command (Required)

• SIP: Using the restart Command (Required)

• Verifying Basic Calling (Optional)

SCCP: Using the reset Command

To reboot and reregister one or more SCCP phones, including contacting the DHCP server for updated information, perform the following steps.

Prerequisites

•Phones to be rebooted are connected to the Cisco Unified CME router.

SUMMARY STEPS

1. enable

2. configure terminal

3. telephony-service
or
ephone phone-tag

4. reset {all [time-interval] | cancel | mac-address mac-address | sequence-all}
or
reset

5. end

DETAILED STEPS


	Command or Action	Purpose
Step 1	enable Example: Router> enable	Enables privileged EXEC mode. •Enter your password if prompted.
Step 2	configure terminal Example: Router# configure terminal	Enters global configuration mode.
Step 3	telephony-service or ephone ephone-tag Example: Router(config)# telephony-service or Router(config)# ephone 1	Enters telephony-service configuration mode. or Enters ephone configuration mode.
Step 4	reset {all [time-interval] \| cancel \| mac-address mac-address \| sequence-all} or reset Example: Router(config-telephony)# reset all or Router(config-ephone)# reset	Performs a complete reboot of the specified or all phones running SCCP, including contacting the DHCP and TFTP servers for the latest configuration information. or Performs a complete reboot of the individual SCCP phone being configured.
Step 5	end Example: Router(config-telephony)# end or Router(config-ephone)# end	Returns to privileged EXEC mode.

SCCP: Using the restart Command

To fast reboot and reregister one or more SCCP phones, perform the following steps.

Prerequisites

•Phones to be rebooted are connected to the Cisco Unified CME router.

SUMMARY STEPS

1. enable

2. configure terminal

3. telephony-service
or
ephone ephone-tag

4. restart {all [time-interval] | mac-address}
or
restart

5. end

DETAILED STEPS


	Command or Action	Purpose
Step 1	enable Example: Router> enable	Enables privileged EXEC mode. •Enter your password if prompted.
Step 2	configure terminal Example: Router# configure terminal	Enters global configuration mode.
Step 3	telephony-service or ephone ephone-tag Example: Router(config)# telephony-service or Router(config)# ephone 1	Enters telephony-service configuration mode. or Enters ephone configuration mode.
Step 4	restart {all [time-interval] \| mac-address} or restart Example: Router(config-telephony)# restart all or Router(config-ephone)# restart	Performs a fast reboot of the specified phone or all phones running SCCP associated with this Cisco Unified CME router. Does not contact the DHCP server for updated information. or Performs a fast reboot of the individual SCCP phone being configured.
Step 5	end Example: Router(config-ephone)# end	Returns to privileged EXEC mode.

SIP: Using the reset Command

To reboot and reregister one or more SIP phones, including contacting the DHCP server for updated information, perform the following steps.

Prerequisites

•Cisco Unified CME 3.4 or later.

•The mode cme command must be enabled in Cisco Unified CME.

•Phones to be rebooted are connected to the Cisco Unified CME router.

SUMMARY STEPS

1. enable

2. configure terminal

3. voice register global
or
voice register pool pool-tag

4. reset

5. end

DETAILED STEPS


	Command or Action	Purpose
Step 1	enable Example: Router> enable	Enables privileged EXEC mode. •Enter your password if prompted.
Step 2	configure terminal Example: Router# configure terminal	Enters global configuration mode.
Step 3	voice register global or voice register pool pool-tag Example: Router(config)# voice register global or Router(config)# voice register pool 1	Enters voice register global configuration mode to set parameters for all supported SIP phones in Cisco Unified CME. or Enters voice register pool configuration mode to set phone-specific parameters for SIP phones
Step 4	reset Example: Router(config-register-global)# reset or Router(config-register-pool)# reset	Performs a complete reboot of all phones connected to this router that are running SIP, including contacting the DHCP and TFTP servers for the latest configuration information. or Performs a complete reboot of the individual SIP phone being configured.
Step 5	end Example: Router(config-register-global)# end or Router(config-register-pool)# end	Exits configuration mode and enters privileged EXEC mode.

Verifying Basic Calling

To verify that Cisco IP phones in Cisco Unified CME can place and receive calls through the voice ports, perform the following steps.

SUNNARY STEPS

1. Test local operation.

2. Test local calling area.

3. Test incoming calls.

DETAILED STEPS

Step 1 Test local phone operation. Make calls between phones on the Cisco Unified CME router.

Step 2 Place a call from a phone in Cisco Unified CME to a number in the local calling area.

Step 3 Place a call to a phone in Cisco Unified CME from a phone outside this Cisco Unified CME system.
