As example, the following are the steps to perform a conference call:
1. Call the first attendee.

The context is now one call active and one call on hold.
4. Flash hook then dial the digit 3 to start the conference call.
Call Hold
The Call Hold service allows the user to temporarily put an existing call on hold, usually by using the “flash”
button of the telephone. The user can resume the call in the same way.
You must enable this service for the following services to work properly:

Call Waiting

Second Call

Blind Transfer

Attended Transfer

Conference
flashHookAndDigits The user must perform a flash hook and enter a specific digit to activate a
service. The digit dialed has a different behaviour depending on the
current call context:
• One call active and one waiting call:
Flash hook then dial the digit 2: Answer the waiting call.
• One call active and one call on hold:
Flash hook then dial the digit 1: Terminate the active call and
recover the call on hold.
Flash hook then dial the digit 2: Hold the active call and recover the
call on hold.
Flash hook then dial the digit 3: Enter the conference mode.
Flash hook then dial the digit 4: Transfer the call on hold to the
active call.
When hanging up in this context, the telephone rings to notify the
user there is still a call on hold.
• In conference mode:
Flash hook then dial the digit 2: Return to one active call and one
call on hold.
Flash hook then dial the digit 4: Transfer the second active call to
the first active call.
When hanging up in this context, all calls are finished.
