The Cisco 813 router supports the enhanced voice features in addition to the standard voice features of the Ciso 800 series routers. The enhanced voice features were developed to work with the INS-NET-64 switch used by Nippon Telephone and Telegraph (NTT). For more information about each feature, see the following topics:
The following is a list of requirements for activating the enhanced voice features on the Cisco 813 router:
This feature displays the caller ID information provided by the INS-NET-64 switch on analog telephones connected to the PHONE 1 or 2 port of the Cisco 813 router.
The following is a list of requirements for activating this feature:
 |
Note The caller ID display feature works only on Japanese language display telephones. |
By default, this feature is disabled. To configure this feature, use the Cisco IOS caller-id enable command in the dial-peer configuration command mode.
caller-id enable
[no] caller-id enable
This feature can reject an incoming voice call based on the caller ID information presented to the Cisco 813 router from the INS-NET-64 switch. This feature can block calls for up to ten caller IDs for each local directory number (LDN).
The following requirements must be met before activating this feature:
By default, this feature is disabled. To configure this feature, use the Cisco IOS block-caller command in the dial-peer configuration command mode.
block-caller number
[no] block-caller
where number is the telephone number to block. You can use a period (.) as a wildcard to substitute for one or more numbers to block. For example, to block all numbers ending in the number 5, you can enter the following:
block-caller .5
You can enter up to ten caller ID numbers for each LDN. However, you cannot exceed the maximum of ten numbers. You must remove one or more numbers before you can add any new numbers to block.
If no caller ID numbers are specified for a particular LDN, all voice calls to that LDN are accepted.
The following example configures the router to block calls from the caller whose caller ID number is 4085551234:
router(config)# pots country jp router(config)# dial-peer voice 1 pots router(config-dial-peer)# block-caller 4085551234
To display caller IDs entered for call blocking, use the show run command. The following is an example of caller ID configuration output:
! dial-peer voice 1 pots no forward-to-unused-port call waiting ring 0 registered-caller ring 1 port 1 block-caller 4085551234 block-caller 4085552345
This feature notifies you (by issuing a call waiting tone) of an incoming call while you are connected to an external telephone call. You can choose to place the first call on hold by pressing flash, connect to the second call, then return to the first call after finishing with the second.
Local call waiting on the Cisco 813 differs from standard ISDN call waiting in that this enhanced voice feature does not require a subscription to call waiting from the service provider. This feature uses both B channels of the ISDN line, enabling local call waiting support on the router rather than from the service provider.
This feature is not supported if any of the interactive voice response (IVR) features (such as voice warp, voice select warp, and Nariwake) are in use.
The following requirements must be met before activating this feature:
To configure this feature, use the Cisco IOS pots call-waiting command:
pots call-waiting [local|remote]
The call waiting defaults to remote if this feature is not configured. In that case, the call holding pattern follows the settings of the service provider rather than those of the router.
To display the call waiting setting, use the show run or show pots status command.
|
Note The ISDN call waiting service will be used if it is available on the ISDN line connected to the router even if local call waiting is configured on the router. If ISDN call waiting is used, the local call waiting configuration on the router is ignored. |
The following example configures the call waiting style to follow the local call holding pattern that is set on the router:
router(config)# pots country jp router(config)# pots call-waiting local
This feature conceals the caller ID of the outgoing call from the receiving device.
The following requirements must be met before activating this feature:
According to the NTT specification, dialing the prefix 184 followed by the destination device number will render your caller ID invisible to the receiving party.
The voice warp feature on the INS-NET-64 switch forwards all incoming calls for a terminal device to another device. Voice warp registration, activation, and deactivation requests are sent to the switch for each LDN. The
Cisco 813 router supports the registration, activation, and deactivation requests for any device attached to the PHONE 1 or 2 port. The forwarding function itself is performed by the INS-NET-64 switch.
During the registration phase of the device, you can:
During the activation phase of this feature, you determine whether calls are redirected all the time or only if the receiving device is busy or does not answer within the no-answer time period specified during registration.
This feature can be deactivated after its registration and activation phases.
|
Note The Cisco 813 router supports this feature for one LDN only. If more than one LDN is configured, only the primary LDN can be used with this feature. |
The following requirements must be met before activating this feature:
|
Note Activating the voice warp feature disables the support for the call waiting feature for both local and network calls. |
This feature is configured using the interface on the telephone as specified in the NTT user manual.
To hear the voice warp registration details of a device, use the keypad dialing sequence specified in the NTT user manual. Information is transmitted only by voice.
This feature is an enhanced version of the voice warp feature. You can create a list of incoming caller IDs that is used in call redirection, either by redirecting incoming calls only from matching caller IDs, or by redirecting all calls except those from matching caller IDs.
|
Note The Cisco 813 router supports this feature for one LDN only. If more than one LDN is configured, only the primary LDN can be used with this feature. |
The following requirements must be met before activating this feature:
|
Note Activating the voice select warp feature disables the support for the call waiting feature for both local and network calls. |
This feature is configured using the interface on the telephone as specified in the NTT user manual.
To get voice warp registration details of a device, use the keypad dialing sequence specified in the NTT user manual. Information is transmitted only by voice.
Nariwake checks for caller IDs that you register for each LDN and presents a distinctive ring to the telephone port receiving the incoming call if a match is detected. The Cisco 813 router provides three different ring cadences that you can set for calls from registered and unregistered callers. The number of caller IDs you can register for each LDN at one time is defined by the INS-NET-64 switch and not by the router.
You can register this feature with the list of caller IDs for each LDN, cancel the registration for the LDN, or get registration information from the INS-NET-64 switch.
|
Note The Cisco 813 router supports this feature for one LDN only. If more than one LDN is configured, only the primary LDN can be used with this feature. |
The following requirements must be met before activating this feature:
|
Note Activating the Nariwake feature disables support for the call waiting feature for both local and network calls. |
To configure the ring cadence for this feature, use the
registered-caller ring command in the dial-peer configuration mode:
registered-caller ring cadence
where cadence is a value of 0, 1, or 2. The default ring cadence for registered callers is 1 and for unregistered callers is 0.
The on/off periods of ring 0 (normal ringing signals) and ring 1 (ringing signals for the Nariwake service) are defined in the NTT user manual.
|
Note If your ISDN line is provisioned for the I Number or dial-in services, you must also configure a dial-peer using the Cisco IOS command destination-pattern not-provided. Either port 1 or 2 can be configured under this dial-peer. The router will then forward the incoming call to the voice port 1 using the default cadence 0. See the "Example of Nariwake Configuration" section for details. If more than one dial-peer is configured with destination-pattern not-provided, the router uses only the first dial-peer for the incoming calls. |
To hear the caller ID registration details, use the keypad dialing sequence specified in the NTT user manual. Information is transmitted only by voice.
The following example sets the ring cadence for registered callers to 2.
router(config)# pots country jp router(config)# dial-peer voice 1 pots router(config-dial-peer)# registered-caller ring 2
Add the destination-pattern not-provided command if you also subscribe to the I Number and dial-in services.
router(config-dial-peer)# destination-pattern not-provided
To display the Nariwake ring cadence setting, use the show run command. The following is an example of screen output for Nariwake configuration:
dial-peer voice 1 pots no forward-to-unused-port call waiting ring 0 registered-caller ring 2 port 1 destination-pattern not-provided block-caller 4085552222 block-caller 4085553333
The trouble-call blocking feature causes all future incoming calls from a particular telephone number to be rejected by the network if the recipient activates this feature after the initial call. As the recipient of the call, you are not required to specify the telephone number of the caller and will not be notified of subsequent connection attempts from that telephone number. When this feature is activated, the caller will hear a standard telephone announcement and a disconnect message. For information about the announcement or message, see your NTT user manual.
The number of callers that you can block is defined by the service provider at the time the service is provisioned. If you request an additional telephone number to block after having reached the limit, the oldest number is discarded (unblocked) before the latest telephone number is registered for blocking.
The following requirements must be met before activating this feature:
You can activate, cancel, or request confirmation of the results of your trouble-call blocking by using the keypad dialing sequence specified in the NTT user manual.
|
Note To activate this feature, you must dial the keypad sequence within 60 seconds after you hang up from the call. You will be notified over the telephone whether or not the activation is successful. |
You can disable this feature for only the last registered number or for all numbers registered for blocking. You will be notified over the telephone whether or not the cancellation is successful.
You can request to hear the results of the trouble-call blocking. You will hear the number of attempted calls that were blocked for the past two months.
This feature supports the use of multiple terminal devices with one subscriber line. The telephone numbers of the subscriber line and router ports are assigned by the service provider. Calls coming into any of the assigned numbers will route through the same subscriber line to the terminal device attached to the target port.
The following requirements must be met before activating this feature:
To configure this feature, perform the following steps:
isdn i-number number ldn
where number is a value from 1 to 3 (based on NTT specifications) and ldn is your local directory number configured under the dial-peer. The number variable maps the I number to one of the LDNs.
Step 2 Use the destination-pattern command to set the dial-peer destination pattern to the corresponding LDN:
destination-pattern ldn
The following example shows screen output for two LDNs configured under interface BRI0:
router(config)# interface bri0 router(config-if)# isdn i-number 1 5551234 router(config-if)# isdn i-number 2 5556789 router(config-if)# exit router(config)# dial-peer voice 1 pots router(config-dial-peer)# destination-pattern 5551234 router(config-dial-peer)# exit router(config)# dial-peer voice 2 pots router(config-dial-peer)# destination-pattern 5556789
