Configuration" chapter.
Allows users to redirect connected calls from their phones to another number.
Some JTAPI/TAPI applications are not compatible with the Join and Direct Transfer feature
implementation on the Cisco IP Phone and you may need to configure the Join and Direct
Transfer Policy to disable join and direct transfer on the same line or possibly across lines.
See Set Up Join and Direct Transfer Policy, on page
Transfer: The first invocation of Transfer will always initiate a new call by using the same
directory number, after putting the active call on hold.
Direct Transfer: This transfer joins two established calls (call is in hold or in connected state)
into one call and drops the feature initiator from the call. Direct Transfer does not initiate a
consultation call and does not put the active call on hold.
Some JTAPI/TAPI applications are not compatible with the Join and Direct Transfer feature
implementation on the Cisco IP Phone and you may need to configure the Join and Direct
Transfer Policy to disable join and direct transfer on the same line or possibly across lines.

Trust Verification Services (TVS) enables phones to authenticate signed configurations and
authenticate other servers or peers without increasing the size of the Certificate Trust List
(CTL) or requiring the downloading of an updated CTL file to the phone. TVS is enabled by
default.
The Security Setting menu on the phone displays the TVS information.
