Using the MCU
Security
Password This setting can be used to ensure that only authorized participants are able to
join the conference. The password entered in this field, will be the password a
participant must enter to join the conference. This password can only contain
digits.
When dialing into a password protected conference, the participant is met with
the ‘Password Enquiry’ screen and sound, asking the participant to enter a
password. This can be performed via a menu generated by the videoconferencing
system (H.243 Password) or via DTMF (telephone) tones. Until the correct
password is entered, the participant will not be able to hear or see any of the
other participants. After entering the correct password and confirming (typically
by pressing ‘OK’), the participant will join the conference. When using DTMF
tones, the MCU will automatically accept the password without having to press a
confirmation key.
Should the password be incorrect, the participant is met with the ‘Password
Incorrect’ screen and after a few seconds, the ‘Password Enquiry’ screen and
sound appear again. If the participant enters a wrong password three times, the
participant will be disconnected.
If no password is entered in this field, participants can join the conference
without entering a password.
Encryption The MCU supports Secure conference TF . When selected, all participants in the
conference must support at least standard DES encryption (available on all
TANDBERG endpoints using software version B4.0 or later). Participants not
supporting encryption will be shown the ‘Encryption Required’ screen for 60
seconds before they are disconnected from the conference.
