Understanding Service Parameters


The Service Parameters configuration pages for Cisco CallManager Release 3.0 allow you to configure several different services on selected servers. With the Service Parameters application, you can insert, modify, and delete service parameters for those services.


Caution You will never need to add or delete service parameters unless directed by the Cisco Technical Assistance Center (TAC). Some changes to service parameters may cause system failure.

Additional Information

Refer to the following tables for the different service parameters, and a description of each, that can be configured for each service:

Cisco CallManager Service Parameters

Cisco TFTP Service Parameters

Cisco Messaging Interface Service Parameters

Cisco IP Voice Media Streaming Service Parameters

Database Layer Service Parameters

Cisco CallManager Service Parameters


Caution You will never need to add or delete service parameters unless directed by the Cisco Technical Assistance Center (TAC). Some changes to service parameters may cause system failure.


Note We strongly recommend modifying trace parameters from the Trace Configuration page. Refer to the "Trace" section on page 32-1 for more information.

Used for debugging purposes only. We strongly recommend you do not change the default value. The maximum time allowed for a response from a digit analysis requests. Valid value is any numeric value.

DisplayIEDeliveryFlag

Default: F

HoldType

Default: F

Original Hold Type requires the user to press the hold button to retrieve a call from hold. The new hold allows the user to press the line button on which the held call is stored to retrieve it.

InterfaceIdentifierPresentFlag

Default: F

This flag only applies to the DMS100 protocol for the digital access gateway in the Channel Identification IE of the SETUP, CALL PROCEEDING, ALERTING, and CONNECT messages. The purpose of this parameter is to interoperate with Nortel PBX when the PBX is configured to use the DMS100 protocol.

On an outbound analog access gateway call, compare if the calling party number matches one of the associated analog access ports. If so, then select that port, otherwise make it so all ports with an attendant number assigned to them are not usable for the life of the current call. This forces selection of another analog access device if another analog access gateway has been configured in RoutePoint/RouteGroup. If another analog access gateway has not been configured, the user hears a fast busy signal.
