Cisco 813 Router Enhanced Voice Features (Japan Only)
Call Blocking on Caller ID
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).
Requirements for Activating Call Blocking on Caller ID
The following requirements must be met before activating this feature:
Subscription to the caller ID service on the INS-NET-64 switch. If this 
feature is enabled on the router without the caller ID subscription, the router 
will neither verify telephone numbers from callers nor block their calls.
Configuration of the router using the Cisco IOS command pots country jp.
Configuring Call Blocking on Caller ID
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.

Example of Caller ID Blocking Configuration
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-caller4085551234
Example of Caller ID Blocking Output
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
Local Call Waiting
This feature notifies you of an incoming call while you are connected to an 
external telephone call (by issuing a call waiting tone). 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 router 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.

Requirements for Activating Local Call Waiting
The following requirements must be met before activating this feature:
Subscription to any telephone service provider switch
Configuration of the router using the Cisco IOS command pots country jp
Configuring Local Call Waiting
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.
NoteThe 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.
Example of Local Call Waiting Configuration
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

E Ya Yo
This feature conceals the caller ID of the outgoing call from the receiving device.
Requirements for Activating E Ya Yo
The following requirements must be met before activating this feature:
Subscription to the E Ya Yo service
Subscription to the INS-NET-64 switch
Configuration of the router using the Cisco IOS command pots country jp
Configuring E Ya Yo
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.
Voice Warp
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:
Create a list of forwarding destination numbers and to select one as the active 
destination.
Specify whether an announcement will be made to the caller or forwarding 
device, or both, at the time the call is forwarded.
Set the no-answer timer parameter from 5 to 60 seconds at 5-second intervals. 
This setting affects the redirection of calls once the voice warp feature is 
activated.

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.
NoteThe 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.
Requirements for Activating Voice Warp
The following requirements must be met before activating this feature:
Subscription to the voice warp and caller ID services
Subscription to the INS-NET-64 switch
Configuration of the router using the Cisco IOS command pots country jp
NoteActivating the voice warp feature disables the support for the call waiting 
feature for both local and network calls.
Configuring Voice Warp
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.
Voice Select Warp
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.

NoteActivating the voice select warp feature disables the support for the call 
waiting feature for both local and network calls.
Configuring Voice Select Warp
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
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.

LDN is configured, only the primary LDN can be used with this feature.
Requirements for Activating Nariwake
The following requirements must be met before activating this feature:
Subscription to the Nariwake feature
Subscription to the INS-NET-64 switch
Configuration of the router using the Cisco IOS command pots country jp
NoteActivating the Nariwake feature disables support for the call waiting feature 
for both local and network calls.
Configuring Nariwake
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.
NoteIf 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.

Trouble-Call Blocking
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.
Requirements for Activating Trouble-Call Blocking
The following requirements must be met before activating this feature:
Subscription to the trouble-call blocking feature
Subscription to the INS-NET-64 switch
Configuration of the router using the Cisco IOS command pots country jp
Configuring Trouble-Call Blocking
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.
NoteTo 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.
I Number
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.
