I wan to work on ethernet switch in gns3 and i want to configure it by myself. It provides entry-level, IP-based voice mail and auto attendant services for small branch office environments. Cisco Unity Express operates under Cisco CallManager Express CME control and is integrated into Cisco's mid-range full service branch office routers for voice and data services in a single network device.

Cisco Unity Express software offers voicemail for as few as users or up to 50 mailboxes for the small branch office of an Enterprise or for the small business with multiple branches.

For further information refer to Cisco Unity Express software product literature and product documentation. Voice network modules convert telephone voice signals into a form that can be transmitted over an IP network.

These modules have one or two slots for installing supported interface cards. An FXS interface connects directly to a standard telephone, fax machine, or similar device. This interface supplies ringing voltage, dial tone, and so on to the station. This is the interface a standard telephone provides. The 1- and 2-port T1 and E1 multiflex trunk interface cards support generic single- or dual-port T1 or E1 trunk interfaces for voice, data, and integrated voice and data applications.

These cards provide basic structured and unstructured service for T1 or E1 networks. The dsl operating-mode command was modified to support these new WICs. Without the NSF configuration, users have to configure their associated gateways as stand-alone H. Cisco CME Version 3. The auto assign command specifies a range of extension numbers to which newly discovered IP phones are automatically assigned.

This method is useful when you have a phone setup in which each phone is assigned a separate, unique extension number. Call pickup allows phone users to retrieve calls from other extension numbers by using the PickUp soft key and dialing the ringing number.

When extensions are assigned to pickup groups, other members of the group can retrieve incoming calls using fewer keystrokes. When night service is active, incoming calls to designated night-service extension numbers will also ring on other phones that are designated as night-service phones. Phone users at the other phones can use call pickup to retrieve the incoming calls.

Call blocking to prevent the unauthorized use of phones is implemented by matching calls to a specified digit pattern during a specified time period. Up to 32 patterns of digits can be specified.

Individual phones can be exempted from call blocking, and individual user logins can override call blocking if they are configured. Ephone hunt groups provide the ability to direct incoming calls for a specific number the ephone hunt group pilot number to a defined group of extensions. Incoming calls are redirected on busy or no answer from extension to extension in the list until they are answered or they reach the number that was defined as the final number.

Secondary dial tone is generated when a phone user dials a predefined digit. The tone terminates when additional digits are dialed. For example, you can configure a secondary dial tone to be heard after the number 9 is dialed to reach an external line. The Cisco IP Phone G, is a cost-effective, entry-level IP phone addressing the voice communications needs of a lobby, laboratory, manufacturing floor, or hallway—or other areas where only basic calling capability is required.

For further information, go to Cisco. The Cisco IP Phone G provides core business features and addresses the communication needs of a cubicle worker who conducts low to medium telephone traffic.

The Cisco IP Phone G offers four dynamic soft keys that guide a user through call features and functions. Phone users access the list of local speed-dial numbers from the Directories button. Phone users access their list of personal speed-dial numbers from the Directories button. Cisco IP Phone and Cisco IP Phone users can enter account codes during call setup or while connected to an active call, using the Acct soft key.

Account codes are inserted into call detail records CDRs on the CME router for later interpretation by billing software. This feature allows callers who dial a busy extension number to request a callback from the system when a called number that was busy is free. Callers can also request callbacks for extensions that do not answer and the system will notify them after the called phone is next used.

When DND is enabled, incoming calls do not ring on the phone, but do provide visual alerting and call information and can be answered if desired. A display message indicates that DND is in effect. Call forwarding on busy and no answer operates the same as without DND.

The set of supported languages varies by phone type. Certain PSTN services, such as three-way calling and call waiting, require hookflash intervention from a phone user.

The Flash soft key is enabled using the fxo hook-flash command. Dual-line extensions are available to handle call-waiting, call transfer, or conferencing using a single button. An extension ephone-dn overlay allows more than one ephone-dn to use the same physical line button on an IP phone. Overlaid ephone-dns can be used to receive incoming calls and place outgoing calls. In particular, the GUI facilitates the routine adds and changes associated with employee turnover, allowing these changes to be performed by non-technical staff.

This person does not have to be trained in Cisco IOS software. The label support feature allows you to enter a meaningful text string to view in the display adjacent to an extension button on an IP phone rather than the extension number that is associated with that button. For multi-button phones and expansion modules, the buttons for extensions that are shared with other phones can be designated as monitor buttons, which show the status of those extensions on the other phones.

When not in use, a monitor line can be used with the Transfer soft key to quickly transfer a call. The Cisco CME system automatically creates a local phone directory based on the telephone numbers that are assigned during the configuration of extensions and phones. Additional entries to the local CME directory can be made using the directory entry command.

The silent ring feature allows you to designate phone buttons that do not emit an audible ring when they receive incoming calls. Although this feature is supported by all phone types, it is most useful on phone buttons that are used to display the activity of shared lines, which are typically found on the Cisco IP Phone and Cisco IP Phone Expansion Module Dual-registration allows SIP IP phones to simultaneously register with both their primary and fallback registrar devices.

The voice register pool configuration provides registration permission control and can also be used to configure some dial peer attributes that are applied to the dynamically created VoIP dial peers when SIP Phone registrations match the pool. The voice gateway responds to the originator with a SIP Redirect message, allowing the SIP phone that originated the call to establish a call to its destination. The first longest match route on a gateway dial-peer destination pattern was used in the Contact header of the message.

With release They are:. With H. SIP gateways now allow the same functionality, but with the registration taking place with a SIP proxy or registrar. SIP gateways allow registration of E.

The Cisco IP Phone G is a single-line IP phone, with fixed feature keys that provide one-touch access to the redial, transfer, conference, and voice-mail access features. This capability gives the network administrator centralized power control—translating into greater network availability. The graphic capability of the display provides a rich user experience by providing calling information and intuitive access to features.

This capability gives the network administrator centralized power control, translating into greater network availability. The combination of in-line power and Ethernet switch support reduces cabling needs to a single wire to the desktop.

The new system message command allows you to edit these display messages on a per router basis. A new keyword has been added to the max-dn command allows you to set IP phones to dual-line mode. Each dual-line IP phone must have one voice port and two channels to handle two independent calls.

This mode enables call waiting, call transfer, and conference functions on a single ephone-dn. Dual-line mode works with all phone types. The date format on Cisco IP phone displays can be configured with the following two additional formats:. A ringing timeout default can be configured for extensions on which no-answer call forwarding has not been enabled.

Expiration of the timeout causes incoming calls to return a disconnect code to the caller. This mechanism provides protection against hung calls for inbound calls received over interfaces such as foreign exchange office FXO that do not have forward-disconnect supervision. The show ephone command has been enhanced to display the following:. Diagnostic messages are added to the system log whenever a phone registers or unregisters from Cisco SRST. For conferencing to be available, an IP phone must have a minimum of two lines connected to one or more buttons.

Several international languages and call-progress tone sets are newly supported. There are approximately 10 new and modified commands. This feature implements the downloading of region-specific tones and the associated frequencies, amplitudes, and cadences using XML-based configuration files during gateway registration.

The feature supports dual tones and sequential tones. Cisco CallManager performs signal and call processing. When Cisco CallManager requests a specific tone, the gateway references the custom tone table associated with the network locale of the voice port. When the gateway registers to Cisco CallManager, or if the gateway restarts or resets, the network locale for each port is downloaded to the gateway.

Once the custom tone specification is downloaded to the gateway, it can also be used in H. Only one gateway supports the download of up to two custom tones, that is, no more than two custom tone tables will be downloaded to one gateway even if there are more that two countries or regions configured for the gateway. The G. All other platforms continue to use the Cisco-proprietary ms EC by default.

Supports new standard. IEEE BackboneFast provides fast convergence in the network backbone after a spanning-tree topology change occurs. If you face any problem setting it up with GNS3 drop me a message and I will get back to you asap.

GNS3 is an open source GNU GPL software that simulates complex networks while being as close as possible from the way real networks perform, all of this without having dedicated network hardware such as routers and switches. GNS3 provides an intuitive graphical user interface to design and configure virtual networks, it runs on traditional PC hardware and may be used on multiple operating systems, including Windows, Linux, and Mac OS X.
