Call Forward Call forward allows a user to configure a Cisco IP Phone, so all calls that are destined for it ring another phone. Three types of call forward exist: Cisco CallManager System Guide OL-7135-01 40-33 Chapter 40 Cisco IP Phones Phone Features • Call forward all—Forwards all calls. • Call forward busy—Forwards calls only when the line is in use and busy trigger setting is reached. • Call forward no answer—Forwards calls when the phone is not answered after the configured no answer ring duration. The administrator can configure call forward information display options to the original dialed number or the redirected dialed number, or both. The administrator can enable or disable the calling line ID (CLID) and calling name ID (CNID). The display option gets configured for each line appearance. The call forward busy trigger gets configured for each line appearance in a cluster 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 there are on a line before the call forward busy setting gets activated (for example, 10 calls). The call forward no answer ring duration gets configured for each line appearance in a cluster, and the default specifies 12 seconds. The call forward no answer ring duration determines how long a phone rings before the call forward no answer setting gets activated. Tip Keep the busy trigger slightly lower than the maximum number of calls, so that users have the ability to make outgoing calls and perform transfers. Configure call forward in the Directory Number Configuration window in Cisco CallManager Administration. Call Park Call park allows a user to place a call on hold, so anyone who is configured to use call park on the Cisco CallManager system can retrieve it. For example, if a user is on an active call at extension 1000, the user can park the call to a call park extension such as 1234, and another use can dial 1234 to retrieve the call. To use call park, you must add the call park extension (in this case, 1234) in Cisco CallManager Administration when you are configuring phone features. For more information about call park, refer to Call Park in the Cisco CallManager Features and Services Guide. 40-34 Cisco CallManager System Guide OL-7135-01 Chapter 40 Cisco IP Phones Phone Features Call Pickup Cisco CallManager provides the following types of call pickup: • Call pickup—Allows you to answer another ringing phone in your designated call pickup group. • Group call pickup—Allows you to answer incoming calls in another pickup group. • Other group call pickup—Allows you to answer incoming calls in a pickup group that is associated with your own group. All three types of call pickup can operate automatically or manually. If the service parameter, AutoCallPickupEnabled, is enabled, the Cisco CallManager automatically connects you to the incoming call after you press one of the following softkeys on the phone: • Pickup—For call pickup (calls in your own pickup group) • GPickup—For group call pickup (calls in another pickup group) • OPickup—For other group call pickup (calls in a pickup group that is associated with your own pickup group) After the call pickup feature is automated, you need to use only one keystroke for a call connection except for group call pickup. You dial the DN of that other pickup group after you press the GPickup softkey on the phone. Note CTI applications supports monitoring the party whose call is picked up. CTI applications does not support monitoring the pickup requester or the destination of the call that is picked up. Hence, Cisco IPMA does not support auto call pickup (one-touch call pickup). You configure the call pickup feature when you are configuring phone features in Cisco CallManager. When adding a line, you can indicate the call pickup group. The call pickup group indicates a number that can be dialed to answer calls to this directory number (in the specified partition). For more information about call pickup, refer to the “Call Pickup” section on page 31-1 and the “Pickup Group Configuration” chapter of the Cisco CallManager Administration Guide. OL-7135-01 Cisco CallManager System Guide 40-35 Chapter 40 Cisco IP Phones Phone Features Call Select The Select softkey allows a user to select a call for feature activation, or to lock the call from other devices that share the same line appearance. Pressing the Select softkey on a selected call deselects the call. When the call gets selected by a device, it gets put in the Remote-In-Use state on all other devices that share the line appearance. No call in the Remote-In-Use state can be selected. In other words, selecting a call instance will lock it from other devices that share the same line appearance. Selected calls are identified by a special display symbol. Call Waiting Call waiting lets users receive a second incoming call on the same line without disconnecting the first call. When the second c...
