Conference Access

When H.323, SIP and ISDN participants connect directly to the
conference, they can be defined or undefined participants. Undefined
Participants can connect to an encrypted conference only if the endpoint's
encryption is set to YES; otherwise, the endpoint's encryption is
considered as if set to NO.
Encrypted ISDN/PSTN Participant can connect to a non-encrypted
conference while encrypted H.323 participants cannot connect to a non-
encrypted conference.
Non-encrypted participants can connect to an encrypted conference only
if they are defined in the conference's participants list (defined
participants) and the system flag
ALLOW_NON_ENCRYPT_PARTY_IN_ENCRYPT_CONF is set to YES.
This flag does not apply to undefined participants. Table 2-15 summarizes
the conference access options for defined participants:
