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.

•
•
When this feature is used, 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 this feature to make a voice call, then it is recommended that you dedicate SPID2 for voice and SPID1 for data.
