I'm not working with Consult buttons but i found
this information.
The Consult button allows a covering user,
after answering a coverage call,
to call the principal (called party) for private
consultation.
Activating Consult places the caller on hold and
establishes a private connection between the
principal and the covering user.
The covering user can then add the caller to
the conversation, transfer the call to the
principal, or return to the caller.
Consult
Allows the covering user, by first pressing the
Transfer button and then the Consult button,
to call the principal (called party) for private consultation.
These two actions place the caller on hold and establish
a connection between the principal and the covering user.
If the principal wishes, the covering user can complete
the conference and add the calling party to the
conversation.
Similarly, the call can be transferred to the principal.
Consult calls use the Simulated Bridged Appearance maintained on the call, if there is one.
If not, the Consult call seizes any idle call appearance.
If there is no idle call appearance,
the Consult call is denied.
