Description Field The fields in this row of fields specify the forwarding treatment for internal calls to this directory number if the directory number is busy. The values in the Destination and the Calling Search Space fields are used to redirect the call to the forward destination. Configure the following values: • Voice Mail—Check this check box to use the configured values in the Voice Mail Profile Configuration window for internal calls. Note When this check box is checked, the calling search space of the voicemail pilot is used. Unified Communications Manager ignores the values in the Destination and the Calling Search Space fields. Note When this check box is checked for internal calls, the system automatically checks the Voice Mail check box for external calls. If you do not want external calls to be forwarded to the voicemail system, you must uncheck the Voice Mail check box for external calls. • Destination—This field indicates the Call Forward Busy destination for internal calls. Use any dialable phone number, including an outside destination. Note When you enter a destination value for internal calls, the system automatically copies this value to the Destination field for external calls. If you want external calls to be forwarded to a different destination, you must enter a different value in the Destination field for external calls. • Calling Search Space—The Forward Busy Internal Calling Search Space is used to forward the call to the Forward Busy Internal destination. It applies to all devices that use this directory number. Note If the system is using partitions and calling search spaces, Cisco recommends that you configure the Call Forward Calling Search Spaces. When a call is forwarded or redirected to the Call Forward destination, the configured Call Forward Calling Search Space is used to forward the call. If the Calling Search Space field is set to None, the forward operation fails if the system uses partitions and calling search spaces. For example, if you configure the Forward Busy destination, you should also configure the Forward Busy Calling Search Space. If you do not configure the Forward Busy Calling Search Space and the Forward Busy destination is in a partition, the forward operation fails. Note When you choose a calling search space for internal calls, the system automatically copies this value to the calling search space setting for external calls. If you want external calls to be forwarded to a different calling search space, you must choose a different value in the Calling Search Space field for external calls. The Call Forward Busy trigger is configured for each line appearance and cannot exceed the maximum number of calls that are configured for a line appearance. The Call Forward Busy trigger determines how many active calls exist on a line before the Call Forward Busy setting is activated (for example, ten calls). Tip Keep the busy trigger slightly lower than the maximum number of calls so that users can make outgoing calls and perform transfers. Tip If a call gets forwarded to a directory number that is busy, the call is not completed.
