We want to be able to see missed calls. Does anyone have recommendations on the best way to handle this. I'd like to use a feature button combo for some users and program a key for a few others. This can be done other than the system attendant, correct?

You can show abandoned calls at any display telephone, by calls to a particuar extension, on a particlar line or group of lines. Keep in mind this will only work if you have Caller ID lines, and that you can determine through programming settings how long to store info. For your application, using buttons programmed for info for trunk groups would probably serve you well.

JBean is correct, but keep in mind that if you have any type of voice mail on your phone system and a call comes in and voice mail picks up the call. These calls WILL NOT be considered abandoned call. The reason for this, is that voice mail are Analog ports on the system and when the vocie mail picks up the call(anwsers it),NOW it is considered a Anwser call; this includes your personal greeting. you can go to Class 4.70.36 and change it to CID/ANI. This will store all call that come into your phone system.

Here some information that might help you further

USAS – CID that is going directly to that extension. – Per Station – This will stay lit when there is telephone number stored

USAT – CID that is going directly to a precise trunk group [Example dial 9 group] - System wide – This will stay lit when there is telephone number stored

USATu – You can choose what trunk group you would like to check [example dial 9 group or 8 group- if programmed] – System wide – This key will not stay lit even when there is telephone numbers stored, because you have to physically choose the group number to view the CID information.

CID information is stored on up to 500 calls in memory. When the number of calls exceeds 500, each new call will overwrite the call that has been saved in memory for the longest time.


CID information can be programmed to be retained 1 and 30 days that call information will be stored in memory. CID records scheduled for deletion are purged from memory at 12:00 AM of the day following the programmed duration. – Default is programmed to clear each day


Stations can be assigned a [UAD] key can delete CID call information saved in system memory, one call at a time. When an CID call message is displayed, pressing the [UAD] key deletes the record from system memory. If an CID call record is accessible at more than one station via either the [USAS], [USATn] or [USAT] key, deleting the record from one station in effect deletes the same record at all stations.
