This document describes the Called-Party-Number Port feature.
The following sections are included:
The Cisco 800 series routers connect small professional offices over Integrated Services Digital (ISDN) Basic Rate Interface (BRI) lines to corporate networks and to the Internet. The routers provide bridging and multiprotocol routing capability between LAN and WAN ports. Cisco IOS Release 12.0(5)T provides software support for the Cisco 800 series routers.
Some switches do not include a called-party number when they send a voice call to a Cisco 800 router. These calls are directed to port 1 by default. The feature Called-Party-Number Port allows the router to direct calls of this type to a specified port. When this feature is combined with the command forward-to-unused-port, the router can direct a second call to the same port as the first call or to another port.
Setting this command allows a Cisco 800 router to direct calls containing no called-party number to specified ports instead of always having these calls directed to port 1, which is the default port. It allows calls to be directed to ports that are not busy.
The Called-Party-Number Port capability for the command dial-peer voice pots requires a dial peer with a destination of not-provided. If this destination is not included in the command, when a switch sending a voice call does not include a called-party number to a specified port, the Cisco 800 directs the call to POTS port 1.
The Called-Party-Number Port feature is supported on the following platforms:
None
This section describes setting up the Called-Party-Number Port feature in the Cisco 800 series routers. The following tasks describe the configuration steps:
.
| Step | Task | Command |
|---|---|---|
Step 1 | Enter configuration mode. | configure terminal |
Step 2 | Create a new dial peer for incoming calls without a called-party number. | dial-peer voice tag pots |
Step 3 | Specify not-provided as the destination pattern. | destination-pattern { ldn | not-provided } |
Step 4 | Select the port to which the call will be directed. | port port |
Step 5 | Disable or enable the automatic forward to an unused port. | [no] forward-to-unused-port |
See the section "Examples" in the "Command Reference" section for examples of the command destination-pattern not-provided.
This section documents new and modified commands. All other commands used with this feature are documented in the Cisco IOS Release 12.0(5)T command reference publications. This section documents the new command that configures the Called-Party-Number Port feature.
Use the interface configuration command destination-pattern to specify an ISDN directory number for a telephone interface. Use the command destination-pattern not-provided to specify the port to receive the incoming calls that have no called-party number. Use the no form of the command destination-pattern to disable a specified ISDN directory number.
destination-pattern { ldn | not-provided }
no destination-pattern
ldn | Specify the local ISDN directory number for the telephone interface, which is assigned by your telephone service provider. |
not-provided | Enable the Called-Party-Number Port feature, which causes the router to use the dial peer for all the incoming calls that have no called-party number. |
No default ISDN directory number is defined.
If a dial peer with a destination of not-provided is not configured---that is, if the feature Called-Party-Number Port is not used---the Cisco 800 directs calls without a called-party-number to port 1.
Interface configuration
| Release | Modification |
|---|---|
Cisco IOS Release 12.0(5)T | The command destination-pattern not-provided was introduced. |
The router allows the destination pattern to be any arbitrary string. Entering not-p and pressing the Tab key does not complete the command not-provided. Therefore, you need to enter not-provided in full.
In the following example, dial peers are not configured with the command destination-pattern not-provided. All incoming calls without a called-party number are therefore directed to port 1.
Router> configure terminal Router(config)> dial-peer voice 1 pots Router(config-dial-peer)> port 2 Router(config-dial-peer)> forward-to-unused-port
In the following example, dial peers are configured with the commands destination-pattern not-provided and no forward-to-unused-port. These commands configure the router to direct all incoming calls without a called-party number to port 2.
Router> configure terminal Router(config)> dial-peer voice 1 pots Router(config-dial-peer)> destination-pattern not-provided Router(config-dial-peer)> port 2 Router(config-dial-peer)> no forward-to-unused-port
In the following example, dial peers are configured with the commands destination-pattern not-provided and forward-to-unused-port. These commands configure the router to direct incoming calls without a called-party number to port 2. If port 2 already has a call, new incoming calls without a called-party number are directed to port 1.
Router> configure terminal Router(config)> dial-peer voice 1 pots Router(config-dial-peer)> destination-pattern not-provided Router(config-dial-peer)> port 2 Router(config-dial-peer)> forward-to-unused-port
| Command | Description |
dial-peer voice pots | Create a dial peer that determines how incoming calls are routed to the telephone ports. |
forward-to-unused-port | Enable the dial peer to forward incoming calls to an unused port. |
port | Specify a telephone port to which an incoming voice call is routed. |
show dial-peer voice pots | Display the dial-peer voice POTS configurations. |
