Feature Overview

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(4)T provides software support for the Cisco 800 series routers.

Configuring outgoing SPID hunt allows the router to seek a free service profile identifier (SPID) to use for outgoing voice calls. If no calls are in process, the SPID associated with the dial-peer destination is used. If a call is already in process, the router seeks a free SPID for the voice call, without bumping the data call. The default for this feature is off.

Benefits

Setting this command allows a voice call to be made at the same time as a data call. If there is already a data call, it is not bumped. The router seeks another free SPID for the voice call. If this feature is not enabled, the voice call fails if the switch is DMS-100 or DMS NI1 but succeeds if it is 5ESS custom or 5ESS NI1. If you have one data call on the router and you get a busy tone when you try to make a voice call, use this feature.

Note This feature must be enabled in order to use the voice features of the Cisco 800 series routers.

Restrictions

This section describes the restrictions or limitations that apply to the outgoing SPID hunt feature. The restrictions include the following:

The outgoing SPID hunt command applies to U.S. switch types only.
If you use the Calling Party Number feature, the calling party number associated with the call you make may change depending on the SPID chosen for the voice call.
If you always dedicate one channel to data and find that you need Incoming Voice Call feature to make a voice call, then it is recommended that you dedicate SPID2 for voice and SPID1 for data.

Supported Platforms

Cisco IOS Release 12.0(4)T is supported on these platforms:

Cisco 801 router
Cisco 802 router
Cisco 803 router
Cisco 804 router

Supported Standards, MIBs, and RFCs

Configuration Tasks

This section describes setting up the outgoing SPID hunt feature in the Cisco 800 series routers.

Setting up the automatic search of a free SPID to use for outgoing voice calls
Verifying that the outgoing SPID hunt is enabled

Setting up Automatic Search of a Free SPID to Use For Outgoing Voice Calls

The following tasks describe the configuration steps for setting up outgoing SPID hunt.

This task applies to U.S. switching only.

Step Task Command

Step 1

Enter configuration mode.

configure terminal

Step 2

Disable or enable the automatic search of a free SPID when a voice call is made.

[no] POTS outgoing-hunt

Step	Task	Command
Step 1	Enter configuration mode.	configure terminal
Step 2	Disable or enable the automatic search of a free SPID when a voice call is made.	[no] POTS outgoing-hunt

Verifying that Outgoing SPID Hunt is Enabled

Use the following conditions to verify a successful configuration:

Your router is connected to a DMS-100 or DMS NI1 switch.
You have one data call on the router.
You make a voice call but the POTS port used for the voice call is associated with the same SPID as the existing data call.
If the feature is not used then you'll get a busy tone. If the feature is enabled then the voice call will go through.

Configuration Examples

None

Command Reference
