Advanced Call-Handling
Advanced call-handling tasks involve special (non-standard) features that your system administrator might configure for your phone depending on your call-handling needs and work environment. You will not have access to these features by default.
Storing and Retrieving Parked Calls
You can "park" a call when you want to store the call so that you or someone else can retrieve it from another phone in the Cisco CallManager system (for example, at a co-worker's desk or in a conference room).
Call Park is a special feature that your system administrator might configure for you.
If you want to...
|
Then...
|
Store an active call using Call Park
|
During a call, select more > Park. The LCD screen displays the special call park number at which the call is stored. Make a note of the call park number and hang up.
|
Retrieve a parked call
|
Enter the call park number from any Cisco IP Phone in your network to connect to the call.
|
Note 
You have a limited amount of time to retrieve the parked call before it reverts to ringing at its original destination. See your system administrator for this time limit.
Redirecting a Ringing Call to Your Phone
Call PickUp allows you to redirect a call that is ringing on a co-worker's phone to your own phone so that you can answer it.
Call PickUp is a special feature that your system administrator might configure for you, depending on your call-handling needs and work environment. For example, you might use this feature if you typically share call-handling responsibilities with co-workers.
If you want to...
|
Then...
|
Answer a call that is ringing on another extension within your group
|
Go off-hook and press more > PickUp. The call now rings on your phone. Press Answer.
|
Answer a call that is ringing on another extension outside of your group
|
Go off-hook and press more > GPickUp. Dial the call group pickup number provided by your system administrator. The call now rings on your phone. Press Answer.
|
Note A Call Pickup "group" is defined by your system administrator.
Understanding Shared Lines
Your system administrator might give you a "shared" line. Shared line features do not apply to standard, unshared lines. Typically, a shared line has two main uses:
•One person applies a shared line to multiple phones—For example, your shared line, extension 23456, applies to your desk phone and your lab phone. An incoming call to extension 23456 rings on your desk and lab phone, and you can use either of the phones to answer the call.
•Multiple people share a line—For example, you are a manager who shares a line and extension number with your assistant. An incoming call to the extension rings on both of your phones.
Remote In Use
You can make calls using a shared line just as you would using any other line — even when your phone displays "remote in use". Remote in use indicates that a co-worker who is sharing your line is using their phone. When your phone displays "remote in use", you may also see information about your co-worker's call such as the called party and call duration. Conversely, when you are using a shared line, information about your call may be displayed on your co-worker's phone. If you are sharing a line and do not want other people to see information about your calls, enable the privacy feature for your phone. See "Preventing Others from Viewing or Joining a Shared-Line Call" section for details about how to use the Privacy feature with a shared line.
Tip If you have privacy enabled on a shared line and make a call, "remote in use" will not be displayed on other phones that share the line.
Maximum Supported Calls on a Shared Line
Your system administrator can configure your shared line to support a different number of calls than your co-workers who share the line with you. Thus, at times you might not be able to make a new call on the shared line even if your co-worker can.
For example, you have a shared line extension, 78888, and your phone is configured to support a maximum of four calls on that shared line. However, one of your co-workers has a phone that supports a maximum of five calls on the same shared line, 78888. If there are already four active calls on the shared line, the NewCall softkey is unavailable to you, and you cannot make a new call using the shared line. However, your co-worker would be able to make a new call on the shared line because her phone supports a maximum of five calls on the shared line, not just four.
Adding Yourself to a Shared-Line Call
If you use a shared line, you can use cBarge to join an in-progress call and convert it to a standard conference. This gives you and all call participants the same features available in standard conferences (see the "Making Conference Calls" section for details), and you can add additional participants to the call.
When you use cBarge, other parties on the call hear a tone and brief interruption in the call, and call information changes on the screen. When you hang up, the call remains as a conference call provided at least three participants remain.
If you want to...
|
Then...
|
View active calls on the shared line
|
Look at your phone display. If it says "remote in use" there are active calls on the shared line. Information for all non-private calls will be displayed. However, if a co-worker who is sharing your line has privacy enabled and has active calls, you will not see any indication that the line is in use.
|
Add yourself to a remote in use call and establish a conference call
|
Choose the remote in use call you want to join and press cBarge.
|
Note You cannot use cBarge to join an in-progress call if the initiator has privacy enabled.
Preventing Others from Viewing or Joining a Shared-Line Call
If you use a shared line, you can use the privacy feature to prevent others who share this line from viewing or joining your calls on this line.
If you want to...
|
Then...
|
Turn on the privacy feature to prevent others from viewing or joining any calls on a shared line
|
Press more > Private. When privacy is turned on, the privacy on icon  displays next to your phone number on the LCD screen.
|
Turn off the privacy feature to allow others to view or join any calls on a shared line
|
Press more > Private. When privacy is turned off, the privacy off icon  displays next to your phone number on the LCD screen.
|
Tips
•If you have privacy enabled on a shared line and make a call, "remote in use" will not be displayed on other phones that share the line; there is no indication when the line is in use.
•If all other phones that share the same line have privacy enabled, you can still make new calls using the shared line. However, you cannot join any in-progress calls using the shared line.
•The privacy feature applies to all shared lines on the phone. Consequently, if you have multiple shared lines on your phone and privacy is enabled on your phone, no one who shares any line with your phone will be able to view or join your calls on any of the shared lines.
Tracing Suspicious Calls
If you are receiving suspicious or malicious calls, your system administrator can add the Malicious Call Identification (MCID) feature to your phone. This feature enables you to identify an active call as suspicious, which initiates a series of automated tracking and notification messages.
If you want to...
|
Then...
|
Identify a suspicious call
|
Press MCID. If the MCID request is successful, you will hear a special tone and see the message, "MCID successful" on your phone. The call remains active until you end the call.
|
Prioritizing Critical Calls
In some specialized environments, such as military or government offices, you might need to make and receive urgent or critical calls. These critical calls might require higher priority handling, such as being able to bypass other calls. If you have the need for this specialized call handling, your system administrator can add Multilevel Precedence and Preemption (MLPP) to your phone.
Keep these terms in mind:
•Precedence indicates the priority associated with a call.
•Preemption is the process of ending an existing, lower priority call while accepting a higher priority call that is sent to your phone.
If you want to...
|
Then...
|
Choose a priority (precedence) level for an outgoing call
|
Contact your system administrator for a list of corresponding precedence numbers for calls (ranging from low to highest).
|
Make a priority (precedence) call
|
Enter the MLPP access number (which is provided by your system administrator) followed by the phone number.
|
Receive a priority (precedence) call
|
Hear the special call waiting tone and note the special icon displayed for the incoming call.
|
View the priority level of a call
|
Higher priority calls display at the top of your call list. The following icons indicate the assigned priority:
(no icon) Normal (routine) call
Priority call
Medium priority (immediate) call
High priority (flash) call
Highest priority (flash override) call
|
Accept an higher-priority call
|
When you hear the special call waiting tone, end the active call and answer the higher-priority call.
|
Receive a preemption call
|
While on an active call, you hear a continuous tone for about 10 seconds. The preemption call then overrides the active call.
|
Tips
•When you make or receive an MLPP-enabled call, you will hear special ring tones and call waiting tones that differ from the standard tones.
•If you enter an invalid MLPP access number, a verbal announcement will alert you of the error.
