Note The Fast Ethernet port and compact Flash slot, though available on the hardware, are not supported by the Cisco Unity Express network module. The Cisco IDS network module provides full-featured intrusion-protection services within the Cisco or Cisco router.
The Cisco IDS network module provides the ability to inspect all traffic traversing the router, to identify malicious activity, and to terminate illegitimate traffic. For instructions on accessing the IDS documentation on Cisco. 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.
Internet Group Management Protocol IGMP snooping constrains the flooding of multicast traffic by dynamically configuring the interfaces so that multicast traffic is forwarded only to those interfaces associated with IP multicast devices.
Per-port storm control prevents broadcast, multicast, and unicast storms. Per-port storm-control uses rising and falling thresholds to block and then restore the forwarding of broadcast, unicast, or multicast packets. You can also set the switch to shut down the port when the rising threshold is reached.
A routed port is a physical port that acts like a port on a router; it does not have to be connected to a router. A routed port is not associated with a particular VLAN, as is an access port. A routed port behaves like a regular router interface, except that it does not support subinterfaces. Routed ports can be configured with a Layer 3 routing protocol.
Fallback bridging forwards traffic that the multilayer switch does not route and forwards traffic belonging to a nonroutable protocol such as DECnet.
There are 47 new Cisco IOS commands that support the feature enhancements. For additional information on the feature enhancements, also refer to the and Port Ethernet Switch Module for Cisco Series, Cisco Series, and Cisco Series feature module at:.
Should connection to the primary call manager fail, call processing reverts to a backup call manager until the connection to the primary is restored. Should connections to the primary and all backups fail, call processing reverts to H. When a connection is restored, call processing reverts to the primary or other available call manager and to MGCP.
You need a supported Cisco series, Cisco series, or Cisco series router equipped with the following:. You need one or more Cisco CallManager systems, Version 3. This feature delivers Private Line Automatic Ringdown for the connection of turrets for the financial industry—primarily for corporations and enterprises that use turrets and POTS telephones for trading. Implementation of this feature ensures that a call between traders on a PLAR connection will be maintained if one of the traders goes on-hook or on-hold.
This new capability also ensures that bandwidth is used only when needed. For additional feature and configuration information, refer to the Private Line Automatic Ringdown for Trading Turrets feature module at:. When a voice port is configured with an incorrect destination number that may or may not be a valid number, the call may not perform as expected. There is no cross-checking for turret PLAR from the origination voice port, but there is a check on the terminating voice port to prevent accepting a call from a calling party that is not preconfigured.
These network modules provide the ability to directly connect the PSTN and legacy telephony equipment to Cisco XM series, Cisco series, and Cisco series modular access routers, enabling important applications such as IP telephony, toll bypass, and full gateway integration.
These network modules support the following interface cards:. Features supported in this release include the following:. In addition to continuing support for configuring a fixed number of channels per DSP, the flex option enables the DSP to handle a flexible number of channels. The total number of supported channels varies from 6 to 16, depending on which codec is used for a call. All the signaling is transparently sent between the analog voice port and DS0 time slot, and will not be seen by the higher layer voice software.
The following Cisco IOS commands are introduced or modified to support this feature:. Cisco IOS software images are subject to deferral. Cisco recommends that you view the deferral notices at the following location to determine if your software release is affected:. For general information about the types of documents listed in this section, refer to the following documents:.
Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious. Severity 3 caveats are moderate caveats, and only selected severity 3 caveats are included in the caveats document. This section contains open and resolved caveats for the current Cisco IOS maintenance release. These documents lists severity 1 and severity 2 caveats and only selected severity 3 caveats, and are located on Cisco.
Caveat numbers and brief descriptions for Release Note If you have an account on Cisco. To reach the Bug Toolkit, l og in to Cisco. This section describes only severity 1 and 2 caveats and select severity 3 caveats. Symptoms: V. Conditions: This symptom is observed on V. High-speed modem connections V.
The successful exploitation enables an adversary to reset any established TCP connection in a much shorter time than was previously discussed publicly. Depending on the application, the connection may get automatically re-established. In other cases, a user will have to repeat the action for example, open a new Telnet or SSH session.
Depending upon the attacked protocol, a successful attack may have additional consequences beyond terminated connection which must be considered. This attack vector is only applicable to the sessions which are terminating on a device such as a router, switch, or computer and not to the sessions that are only passing through the device for example, transit traffic that is being routed by a router.
In addition, this attack vector does not directly compromise data integrity or confidentiality. All Cisco products which contain TCP stack are susceptible to this vulnerability. Symptoms: A router may reload unexpectedly because of a bus error when it accesses a low address during the translation of TCP port Symptoms: A router may reload unexpectedly after it attempts to access a low memory address.
Conditions: This symptom is observed after ACLs have been updated dynamically or after the router has responded dynamically to an IDS signature. Symptoms: A caller doing a blind transfer sees the error message, "Unable to transfer" on their IP phone even though the destination is ringing.
This might affect the interoperablity between a call manager and IPIP gateway. Symptoms: A voice gateway incorrectly matches the wrong outbound dial-peer using called number digits collected from INFO messages. The dial-peer mismatch occurs when the initial interdigit timeout expires because incorrect called number digits are used to find a matching dial-peer.
Conditions: This happens when the enhanced default application is used on the terminating gateway and the terminating gateway receives a PROGRESS message with an inband progress indicator. Workaround: Configure the "default. Cisco products running IOS contain vulnerabilities in the processing of H.
A test suite has been developed by the University of Oulu to target this protocol and identify vulnerabilities. Support for the H. The vulnerabilities can be exploited repeatedly to produce a denial of service DoS.
There are workarounds available that may mitigate the impact, but these techniques may not be appropriate for use in all customer networks. Symptoms: Ringback is not heard on the originating phone when a blind transfer is initiated. Once the call is established with the destination, the destination party transfers the originating party to another destination. During this transfer, the originating party should hear the ringing for the destination.
Symptoms: A Cisco router that has a voice feature such as H. Conditions: This symptom is observed on a Cisco series but may also occur on other routers. Workaround: Turn off "ip nat service hall" or move to This should make the router send RSIP:restart to the call agent. Further Problem Description: A call setup without an incoming call leg results in a H. Enter set callinfo newguid to force the call setup to generate new conferenceID and callIdentifier fields.
This assumes that the generated GUID does not affect the billing system or the remote endpoint. The symptom occurs when the following debug privileged EXEC commands are enabled:. Symptoms: Onboard framer misses the first FDL request. PRM transmission to CO timing is wrong.
After that, the Cisco IAD operates correctly. Conditions: On the terminating gateway's TGW incoming dial-peer configuration, define a progess indicator for the connect event by using progress-ind connect enable 8. Symptoms: The user is disconnected without any busy tones when transferred to unreachable destination.
Instead, it hears a fastballs and displays unknown number. Conditions: This behavior can occur when the transferee and transfer-to endpoints are attached to the same gateway and the transfer is committed during alerting.
Symptoms: The remote party display information is not updated properly after a call transfer. IP Phone B1 correctly displays "Private.
IP Phone A2 answers. On IP Phone A1 there are 2 displays:. To IP Phone B1. On pressing transfer:. Conditions: This behavior occurs when the default session application is set to process the call. Workaround: Configure the application session command on the incoming dial-peer. Symptoms: The ringback tone provided during alerting and the fast busy tone provided at the end of the call is not as per the cptone configured on the gateway under the voice-port.
The caveats document is updated for every maintenance release and is located on Cisco. Cisco recommends that you view the field notices for this release to see if your software or hardware platforms are affected. If you have an account on Cisco. If you do not have a Cisco. Cisco IOS Release The Cisco IOS software is packaged in feature sets consisting of software images—depending on the platform. Each feature set contains a specific set of Cisco IOS features.
For example, " If a cell in this column is empty, the feature was included in the initial base release. For information about inherited features, refer to Cisco. For Cisco. If you have a Cisco. The following sections list the new hardware and software features supported by the Cisco series routers for Cisco IOS Release After you update information for a phone that is associated with a Cisco IOS Telephony Service ITS router, the phone must be rebooted for the new information to take effect.
Using a sequential reboot minimizes the risk of conflict which can occur when multiple phones attempt to access changed ITS configuration information through TFTP. In addition, the restart command has been added to support quick phone rebooting for use when only the line and speed-dial configuration for a phone is changed. The tool command language TCL script that controls H.
You can continue to use the previous script, called app-htransfer. Any subdivision of bandwidth is performed at each customer site rather than at the central office. The network module requires the use of ACNS 4. The CE network module can operate as a standalone cache or in an integrated enterprise content delivery network E-CDN environment.
As one element of an E-CDN, the CE network module can be deployed with a combination of other content engines, content routers, content services switches, and content distribution managers to create a complete content delivery network system. The Gigabit Ethernet network module provides gigabit connectivity.
The throughput of the interface depends on the platform. The GE network module optimizes the performance for branch office customers by offering a high-speed uplink to both existing and new LAN or WAN environments. The extended reach of the provided fiber connectivity allows customers the option of interconnecting branch offices with Gigabit Ethernet and avoids expensive leased serial lines.
ITS offers a core set of phone features that customers commonly require for their everyday business needs. You also need an account on Cisco. For more information, refer to the document at the following URL:. The V. When compared to V. This release permanently removes selected legacy features or components from the IOS code.
These features will not be available in future releases of Cisco IOS software. Caveats describe unexpected behavior in Cisco IOS software releases.
Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious. Severity 3 caveats are moderate caveats, and only select severity 3 caveats are included in the caveats document. This section contains open and resolved caveats for the current Cisco IOS maintenance release.
Note If you have an account on Cisco. To reach the Bug Toolkit, l og in to Cisco. This section describes only severity 1 and 2 caveats and select severity 3 caveats. Problem: The User Locales do not work when a phone from an 3. CRTP works fine with process switching. Symptom: Disconnect with pi8 is used pretty often in the PSTN world to cut the voice path before disconnecting.
This function is missing while the H. Calls worked with ISDN and analog phones. When "incoming-called number. T" is put in the configuration, not all digits from the called number are collected correctly. The system did not get the last digit. Workaround: Instead of. T, the configuration is changed to exactly match the input digits. Symptom: After a call is transferred, transferee phone is connected to the transfer-to phone; however, the display on transferee phone shows it is connected to the transferrer phone instead.
Respectively after consultation transfer, the transfer-to phone shows it is connected to the transferrer phone instead of the transferee phone. The wrong display on the transferee phone happens on both blind transfer and consultation transfer.
