Conference Policies

These types of policies are policies that are applied when a meeting takes place. Below is a general explanation about the rules and settings of this type of Ethical wall policy. Note that similarly to how the Default P2P policy , the policy conditions can’t be changed in the default conference policy choosing the policy conditions (1st section of the policy) isn’t available. Generally, most of the conference policy rules work in a 2-way manner and can be set to either completely allow a certain feature in a conference or completely block. This is on contrary to P2P policies where a certain rule can have a different behavior if it’s “Incoming” (from side B to Side A) or “Outgoing” (from side A to side B). However certain features (like “Present desktop”) can be set with different “Incoming” and “Outgoing” values.
