Whisper Mode? CM 4.2


Hello again,

We have a business unit which will be involved in sales. The position involves cold calling, in which the manager would like to be able to listen in on the calls.

To date, this has never been requested. I don't recall seeing any feature or function in Call Manager which would be used to assign as such.

Is this possible with Call Manager if Call Center is not installed?

Any help is greatly appreciated.

Thank you

We only provide barge, and that requires shared lines to work.

If they're not going to be shared lines then you need either a contact center solution or look for 3rd party apps that might provide this.

Is this the feature you are looking at? Looks like it requires at least phone firmware 9.1.1. You might need to check if you CUCM version is supported for this feature.

Hope that helps!

Hello, sorry to respond late, I was out yesterday.

Yes, the above link is indeed what we're looking for. However, we're looking to do this in a call manager environment.

If a line is shared and added to two phones. Can one person pick up, get dialtone and make a call? Then the coach open the line on his phone and listen, hitting mute. This way there is no interference?

Thank you

Hi Ross,

You can "listen" with Mute on Barge or cBarge calls (with Shared Lines)

You would need to look at this so you can minimise the Barge notification;

From TAC

In Cisco Communications Manager, the barge beep can be turned off with the Party Entrance Tone service parameter by going to Cisco CallManager administration > Service  > Service Parameter Menu.

This parameter determines whether a tone is be played when a party joins or exits a call with more than two parties. These features play a tone based on this parameter:

    * Barge
    * cBarge
    * Conference
    * Join
    * Meet-Me conference

This tone-playing capability is also limited to the controlling device capability. Only those device types that have a built-in bridge (such as Cisco IP phone models 7940, 7960 and newer) can play a tone to all parties.

When the controlling device is no longer present in the call or lacks the capability, the tone is played to all parties, even if this parameter is True. Valid values are True (play tone) or False (do not play tone). This is a required field. The default value is True.

Barge Using Built-In Conference-Barge Softkey

You can use the Barge softkey only in the remote-in-use call state. A built-in conference bridge proves advantageous because neither a media interruption nor display changes to the original call occur when the barge is being set up. A spinning circle displays at the right side of the prompt status message window at the target device.
