Parameters 
audio: Specifies the audio service.

speech: Specifies the speech service. 
Usage guidelines 
The command is available only on NI-enabled BRI interfaces. 
You can repeat the command to specify multiple services. To specify all the services, execute the 
command without specifying any services. 
If dynamic SPID negotiation is used, the service provider switch sends available SPIDs to the device. 
The device selects the SPID that best suits its service configuration. For example, if you specify the 
data service, the device preferentially selects the SPID that includes only the data service. If you 
specify the audio and data services, the device preferentially selects the SPID that includes both 
services. 
For the device to accept a SPID that includes any service types, use the undo form of the command. 
You cannot execute the command when a SPID negotiation is present on the interface.
