Cisco Unified CME Commands: O

---

First Published: November 11, 2011

This chapter contains commands to configure and maintain Cisco Unified Communications Manager Express (formally known as Cisco Unified CallManager Express). The commands are presented in alphabetical order. Some commands required for configuring Cisco Unified Communications Manager Express (Cisco Unified CME) may be found in other Cisco IOS references. Use the reference master index or search online to find these commands.

olsontimezone

To set the Olson Timezone so that the correct local time is displayed on Cisco Unified SCCP IP phones or Cisco Unified SIP IP phones, use the olsontimezone command in telephony-service or voice register global configuration mode, respectively. To return to the default, use the no form of this command.

olsontimezone timezone version number

no olsontimezone

Syntax Description

timezone	Olson Timezone names, which include the area (name of continent or ocean) and location (name of a specific location within that region, usually cities or small islands).
version number	Version of the tzupdater.jar or TzDataCSV.csv file. The version indicates whether the file needs to be updated or not. Note In Cisco Unified CME 9.0, the latest version is 2010o.

Command Default

No Olson Timezone is set.

Command Modes

Telephony-service configuration (config-telephony)

Voice register global configuration (config-register-global)

Command History

Release	Modification
15.2(2)T	This command was introduced.

Usage Guidelines

Use the olsontimezone command in either telephony-service or voice register global configuration mode, with the current version of Oracle's Olson Timezone updater tool, tzupdater.jar, to set the correct Olson Timezone.

For Cisco Unified 3911 and 3951 SIP IP phones and Cisco Unified 6921, 6941, 6961, and 6945 SCCP and SIP IP phones, the correct Olson Timezone updater file is TzDataCSV.csv. The TzDataCSV.csv file is created based on the tzupdater.jar file.

To set the correct time zone, you must determine the Olson Timezone area/location where the Cisco Unified CME is located and download the latest tzupdater.jar or TzDataCSV.csv to a TFTP server (such as flash or slot 0) that is accessible to the Cisco Unified CME.

After a complete reboot, the phone checks if the version of its configuration file is earlier or later than 2010o. If it is earlier, the phone loads the latest tzupdater.jar and uses that updater file to calculate the Olson Timezone.

To make the Olson Timezone feature backward compatible, both the time-zone and timezone commands are retained as legacy time zones. Because the olsontimezone command covers approximately 500 time zones (Version 2010o of the tzupdater.jar file supports approximately 453 Olson Timezone IDs.), this command takes precedence when either the time-zone or the timezone command (that covers a total of 90 to100 time zones only) is present at the same time as the olsontimezone command.

Examples

The following example shows 7:29 p.m. as the time set on a Cisco Unified 7961 SCCP IP phone in Buenos Aires on May 13, 2011:

Router(config)# tftp-server flash:tzupdater.jar

Router(config)# tftp-server flash:TzDataCSV.csv

Router(config)# telephony-service

Router(config-telephony)# olsontimezone America/Argentina/Buenos Aires version 2010o

Router(config-telephony)# create cnf-files

Router(config-telephony)# time-zone 21

Router(config-telephony)# exit

Router(config)# clock timezone CST -6

Router(config)# clock summer-time date 12 October 2010 2:00 26 April 2011 2:00

Router(config)# exit

Router# clock set 19:29:00 13 May 2011

Router# configure terminal

Router(config)# telephony-service

Router(config-telephony)# reset

The following example shows 3:25 p.m. as the time set on a Cisco Unified 6921 SIP IP phone in Buenos Aires on November 17, 2011:

Router(config)# tftp-server slot0:tzupdater.jar

Router(config)# tftp-server slot0:TzDataCSV.csv

Router(config)# voice register global

Router(config-register-global)# olsontimezone America/Argentina/Buenos Aires version 2010o

Router(config-register-global)# create profile

Router(config-register-global)# timezone 21

Router(config-register-global)# exit

Router(config)# clock timezone CST -6

Router(config)# clock summer-time date 12 October 2010 2:00 26 April 2011 2:00

Router(config)# exit

Router# clock set 15:25:00 17 November 2011

Router# configure terminal

Router(config)# voice register global

Router(config-register-global)# reset

Command	Description
time-zone	Sets the time zone so that the correct local time is displayed on Cisco Unified SCCP IP phones in a Cisco Unified CME system.
timezone	Sets the time zone used for Cisco Unified SIP IP phones in a Cisco Unified CME system.

outbound-proxy system

To specify that all Cisco Unified Communications Manager Express (Cisco Unified CME) line-side phones connected to a Cisco IOS voice gateway use the global settings for forwarding Session Initiation Protocol (SIP) messages to an outbound proxy, use the outbound-proxy system command in voice register global configuration mode. To disable the SIP outbound proxy function for Cisco Unified CME line-side SIP phones, use the no form of this command.

outbound-proxy system

no outbound-proxy system

Syntax Description

This command has no arguments or keywords.

Command Default

The SIP outbound proxy function for all SIP line-side phones in Cisco Unified CME is enabled and behavior is determined by the global setting on the Cisco IOS gateway.

Command Modes

Voice register global configuration (config-register-global)

Command History

Cisco IOS Release	Cisco Product	Modification
12.4(15)XZ	Cisco Unified CME 4.3 Cisco Unified SIP SRST 4.3	This command was introduced.

Usage Guidelines

If global configuration for outbound proxy is enabled on the Cisco IOS voice gateway and Cisco Unified CME receives a call, Cisco Unified CME forwards all SIP messages to the outbound proxy causing incoming calls to line-side SIP phones to fail. This is the default behavior.

To avoid these failed calls, use the no form of this command in voice register global configuration mode to override global outbound proxy settings for the gateway and disable the outbound proxy function for all line-side SIP phones connected to Cisco Unified CME.

To configure outbound proxy settings for an individual dial peer on the gateway, use the voice-class sip outbound-proxy command in dial peer voice configuration mode.

Examples

The following example shows how to disable the global outbound proxy feature for all line-side SIP phones on a Cisco Unified CME:

Router> enable

Router# configure terminal

Router(config)# voice register global

Router(config-register-global)# no outbound-proxy

Related Commands

Command	Description
voice-class sip outbound-proxy	Configures SIP outbound proxy settings for an individual dial peer that override global settings for the Cisco IOS voice gateway.

overlap-signal

To configure overlap dialing in SCCP or SIP IP phones, use the overlap-signal command in ephone, ephone-template, telephony-service, voice register pool, voice register global, or voice register template configuration mode.

overlap-signal

Syntax Description

This command has no arguments or keywords.

Command Default

Overlap-signal is disabled.

Command Modes

Call-manager-fallback
Ephone configuration (config-ephone)
Ephone-template configuration (config-ephone-template)
Telephony-service configuration (config-telephony)
Voice register pool (config-register-pool)
Voice register global configuration (config-register-global)
Voice register template (config-register-template)

Command History

Cisco IOS Release	Cisco Product	Modification
15.1(3)T	Cisco Unified CME 8.5 Cisco Unified SRST 8.5	This command was introduced.

Usage Guidelines

SCCP IP phones

In SCCP IP phones, overlap dialing is enabled when the overlap signal command is configured in ephone, ephone-template, and telephony-service configurations modes.

SIP IP phones

In SIP IP Phones, overlap dialing is enabled when the overlap signal command is configured in voice register pool, voice register global, and voice register template configuration modes.

Cisco Unified SRST

In Cisco Unified SRST, overlap dialing is enabled on SCCP IP phones when overlap signal command is configured in call-manager-fallback configuration mode.
