Conference Bridge connects a number people participating
in conference-calls. It represents itself a server that works as a telephone
and can respond to many calls simultaneously.
“Call filter” allows blocking/unblocking the incoming calls as easy as to make filtration, it also journalizes all rejected calls. It is very convenient if you do not want to receive a call from some subscribers, when they will call you, “Call filter” will do so that your line is engaged.
