Hi Prakash,
Here is an excerpt from the config guide
Barge Using Shared Conference-cBarge Softkey
You can use the cBarge softkey only in the remote-in-use call state. No standard softkey template includes the cBarge softkey. To access the cBarge softkey, the administrator adds it to a softkey template and then assigns the softkey template to a device.
When cBarge gets pressed, a barge call gets set up by using the shared conference bridge, if available. The original call gets split and then joined at the conference bridge, which causes a brief media interruption. The call information for all parties gets changed to Barge.
Barge with Shared Conference Bridge (cBarge) Configuration Checklist
Configuration Steps
Step 1
Assign the Standard User or Standard Feature softkey template (you configure cBarge to either template) to each device that accesses Barge by using the shared conference bridge.
Step 2
Set the optional clusterwide service parameter Party Entrance Tone to True (required for tones).
Step 3
In the User Configuration window for each user that is allowed to access the cBarge with shared conference bridge feature, associate the device that has the cBarge softkey template that is assigned to it.
Cheers!
Rob
