Any way to disable auto pick of all extensions on phone?

Unanswered Question
Mar 21st, 2007


I recently had a request from a user for the following:

Users in this specific department have multiple lines assigned to their phones. 3344, 3345, 3346, 3347, 3348. Is there a way to disable auto pickup of all extensions?

I.e. A users primary extension is 3344. Someone is calling on 3345. The user wants to dial an outgoing call on 3344 instead of picking up the incoming call on 3345. If this makes any sense.

We are on ccm 4.0(2). Thanks in advance

I have this problem too.

Hi Marcus,

Set the Always Use Prime Line parameter to True in Cisco CallManager. Because this parameter is clusterwide, any change affects all the phones. There is no interruption to the call handling and no need to restart any service or reboot the Cisco CallManager server.

In order to change this parameter, log in to the Cisco CallManager Administration page and perform these steps:

From the Service menu, choose Service Parameters.

Choose Publisher CallManager Server > Cisco CallManager service.

Under the Clusterwide Parameters (Device - Phone) section, scroll down to the Always Use Prime Line parameter, choose True for this parameter, and click Update.

Note: The default value for the Always Use Prime Line parameter is False. If the flag is set to True, when the phone goes off-hook or the speaker button is pressed, then the primary line is chosen and becomes the active line. If a call comes in on the second line of a user, going off-hook makes only the first line active. In this case, the user must select the second line in order to answer the call. If the flag is set to False, the phone automatically chooses a line as the active line based on the line status.

From this doc;

Hope this helps!

Is this option set cluster wide? I.e if I turn this option for this department, it will affect all other departments on campus?

Hi Marcus,

This parameter is clusterwide, any change effects all the phones. Sorry, there is no device by device setting (or Device Pool type setting) :(

Hope this helps!

It helps, but I dont think the rest of the company is willing to give up the option to pickup all extensions. If anyone knows a workaround on a phonebyphone basis, please let me know
