Call Transfer
Description
Call transferring is a function that allows users to manually redirect calls to another
recipient. This allows for a call participant to talk to an appropriate party without
having to make a new call.
Getting Started
Call Transferring is available by default on the UCM. To use it:
1. Make sure the feature codes for Blind Transfer, Attended Transfer, and
Seamless Transfer are configured in Call Features
Maps and that they are not disabled.
2. The following transfer types are available:
a. Blind Transfer – After dialing the number to transfer to, the
transferring party is immediately disconnected. During this transfer
process, music on hold will play for the transferred party. The default
feature code is #1.
b. Attended Transfer – After dialing the number to transfer to, the
transferring party places the current call on hold and rings the new
recipient. Generally, the transferring party confirms that the
recipient is available before completing the attended transfer. The
default feature code is *2.
c. Seamless Transfer – After dialing the number to transfer to, the
existing call will continue until the transfer recipient picks up. The
transferring party will be disconnected upon pickup. No music on hold
will play during the transfer process, and the transferred party will
receive no indication of being transferred. This gives the impression
of the transferring party physically handing the phone over to
another party. The default feature code is *44.
Making a Blind Transfer
Assuming the following:
• A, B, and C are SIP extensions registered to the UCM.
• The blind transfer feature code is set to "Allow Both".
• #1 is the configured feature code to initiate a blind transfer.
