This interface supports controlling which contacts are allowed
to initiate text chats, incoming calls, and other forms of
communication as supported by the underlying protocol. The
policies supported for different communication methods on this
connection are listed in the
The active communication policies on this connection. Communication methods that are not in this mapping are considered open.
For example, to allow incoming calls only from contacts buddy list, and to allow text messages from anyone, the policy would look like this:
{ 'org.freedesktop.Telepathy.Channel.Type.Text' : Access_Control_Type_Open, 'org.freedesktop.Telepathy.Channel.Type.Call' : Access_Control_Type_Publish_List }
Changes to this property are signalled by
The communication methods (channel types), and the policies that can be applied to them. This is server and protocol dependant.
Grouped channel types will always have the same policy applied to them.
