6-45 Cisco 800 Series Software Configuration Guide 78-5372-06 Chapter 6 Configuring Telephone Interfaces Cisco 813 Router Enhanced Voice Features (Japan Only) Silent Fax Calls The silent fax calls feature enables you to configure your router port to send a silent fax tone instead of a ring alert, which is recognized by fax machines with silent fax recognition capability (Smart Fax type 2). With the silent fax feature, the fax machine does not ring but the fax call get connected. If a phone is connected instead of a fax machine, the phone will not ring. Configuring Silent Fax Calls To configure your telephone port as a silent fax type 2, use the Cisco IOS silent-fax command in dial-peer configuration mode: silent-fax no silent-fax By default, this feature is disabled. Example of Silent Fax Calls Configuration The following is an example of a silent fax call configuration: router# configure terminal router(config)# dial-peer voice 1 pots router(config-dial-peer)# silent-fax Example of Silent Fax Calls Configuration Output The following is an example of the silent fax configuration output: dial-peer voice 1 pots caller-id no forward-to-unused-port call-waiting ring 0 no silent-fax registered-caller ring 1 port 1 volume 3 destination-pattern 7773000 ! dial-peer voice 2 pots

Supplementary Telephone Services for the Net3 Switch The Cisco 800 series routers now support the following plain old telephone service (POTS) features for the European Telecommunications Standards Institute (ETSI) Net3 switch type: Caller ID presentation and restriction are available for Denmark and Finland. For more information, see the “Configuring Caller ID for the Net3 Switch” section on page 6-47. Calling line identification restriction (CLIR) temporarily prevents your calling ID from being presented to the destination number for an outgoing call. You must configure CLIR before each call that you wish to restrict. Call forwarding is enabled by using Cisco IOS and dual tone multifrequency (DTMF) commands. For more information, see the “Call Forwarding for the Net3 Switch” section on page 6-48. Call transfer enables you to connect two call destinations. The request for this service must originate from an active, outgoing call. Requirements for Supplementary Telephone Services Support You must subscribe to the following Net3 switch services for these supplementary telephone services to work: Calling line identification presentation (CLIP) CLIR in temporary mode

Configuring Caller ID for the Net3 Switch
To enable caller ID on the Net3 switch, configure the country type by using the
Cisco IOS pots country command in global configuration mode:
pots country {dk|fi}
NoteCaller ID for the Net3 switch is always enabled, provided that the POTS
country type is correctly defined. Caller ID cannot be disabled using the
Cisco IOS command-line interface (CLI).
To verify whether caller ID is enabled, use the show pots status command. The
following is an example of the output from that command:
router# show pots status

Chapter 6 Configuring Telephone Interfaces Supplementary Telephone Services for the Net3 Switch 6-48 Cisco 800 Series Software Configuration Guide 78-5372-06 Call Forwarding for the Net3 Switch The following types of call forwarding services (for voice calls only) are supported on the Net3 switch: Call forward unconditional (CFU) redirects your calls without restrictions and takes precedence over other call forwarding types. Call forward busy (CFB) redirects your call to another number if your number is busy. Call forward no reply (CFNR) forwards your call to another number if your number does not answer within a specified period of time. You can select one or more call forwarding services at a time. However, CFU has the highest precedence, CFB the next highest, and CFNR the lowest. The default setting is that no forwarding type is selected. NoteIf you had configured call forwarding for a POTS port and the router finds that a dial peer is also configured for that port, call forwarding works only for the number defined in the destination-pattern dial-peer command and ignores all other numbers for that telephone. If the router does not find a dial peer, or if the destination pattern is not defined, call forwarding works for all numbers allocated to the ISDN line. To enable and configure this feature, follow these steps: Step 1Enable and select the call forwarding method. See the “Configuring the Call Forwarding Method” section on page 6-49. Step 2Configure your call forwarding service, depending on which method you previously selected: Functional method—Enter DTMF commands on the telephone keypad. For more information, see the “Configuring the Call Forwarding Service” section on page 6-49. Keypad method—Follow the instructions in your Net3 switch documentation.

Configuring the Call Forwarding Method
You can select the method by which the call forwarding feature is controlled:
Functional method gives control to the router. If you select this method, use
the DTMF commands documented in the “Configuring the Call Forwarding
Service” section on page 6-49.
Keypad method gives control to the Net3 switch.
To enable the call forwarding method, use the Cisco IOS pots
forwarding-method command in global configuration mode:
pots forwarding-method {functional | keypad}
no pots forwarding-method
NoteUse the pots forwarding-method command to configure only Net3 switch
types. This command does not work for other switch types. This feature is
disabled in the default setting.
The following example configures the call forwarding feature to give control to
the router:
router# configure terminal
router(config)# pots forwarding-method functional

Chapter 6 Configuring Telephone Interfaces Supplementary Telephone Services for the Net3 Switch 6-50 Cisco 800 Series Software Configuration Guide 78-5372-06 You should hear a dial tone after you enter the DTMF commands if the call forwarding service is successfully configured. If you hear a busy signal, the command is invalid or the switch does not support that service. Displaying POTS Status Use the show pots status command to display details of the call forwarding type. This status is not stored when you reboot.

Chapter 6 Configuring Telephone Interfaces Cisco 804 and 813 Routers Enhanced Voice Features 6-52 Cisco 800 Series Software Configuration Guide 78-5372-06 Cisco 804 and 813 Routers Enhanced Voice Features The Cisco 804 and 813 routers support the following enhanced voice features. For information on each feature, see the following topic: Prefix Dialing Calling Between Telephone Ports Redial Call Transfer Volume Adjustments Distinctive Ringing Based on Caller ID Subaddresses for POTS Ports Caller ID on the Cisco 813 Router Prefix Dialing Cisco 803 and Cisco 804 routers support prefix dialing. You can add a telephone prefix and create a prefix filter to the dialed number for analog telephone calls. When a telephone number is dialed through the telephone port, the router checks for prefix filters. If the router finds a match, no prefix is added to the dialed number. If no filter match is found, the router adds the user-defined prefix to the called number. Configuring a Prefix Number To set a prefix to be added to a telephone number called, use the Cisco IOS pots prefix number command in global configuration mode: pots prefix number number no pots prefix number where number is a prefix number from 1 to 5 digits in length. Only one prefix can be configured at a time, and configuring a new number will overwrite the existing one.
6-53 Cisco 800 Series Software Configuration Guide 78-5372-06 Chapter 6 Configuring Telephone Interfaces Cisco 804 and 813 Routers Enhanced Voice Features The following example sets the prefix number to 12345: router# configure terminal router(config)# pots prefix number 12345 Configuring a Prefix Filter You can configure a prefix filter that is compared to the digits that you dial. If a match occurs, the prefix number is not added to the called number. To create a prefix filter, use the pots prefix filter command in global configuration mode: pots prefix filter number no pots prefix filter number where number is a prefix filter from 1 to 8 digits in length. You can define up to ten filters for your router. If you have reached the maximum number of filters defined, no new filter configurations are accepted until you remove at least one existing filter number using the no pots prefix filter number command. The following are examples of how to set prefix filters: router# configure terminal router(config)# pots prefix filter 192 router(config)# pots prefix filter 1 router(config)# pots prefix filter 9 router(config)# pots prefix filter 0800 router(config)# pots prefix filter 08456 Calling Between Telephone Ports The calling between telephone ports voice feature enables a connection between the two telephone ports of your router. This voice call is handled by the router and does not affect any data calls handled on the B channels. However, the following restrictions apply: During a call between ports, an incoming voice call cannot supersede the data calls. The router sends a disconnect message to the network for incoming voice calls. If voice priority is set on the router and two data calls are in progress, an attempted call between ports takes precedence over one of the data calls. This applies to the overlap mode of dialing.
Chapter 6 Configuring Telephone Interfaces Cisco 804 and 813 Routers Enhanced Voice Features 6-54 Cisco 800 Series Software Configuration Guide 78-5372-06 The call waiting tone is not activated for the local telephone ports even if call waiting is enabled locally or at the switch. An external calling party hears a busy tone if the telephone ports are engaged.
