The Chat Room allows you to organize a small 7-party call conference. The Chat Room extension can be called by local PBX extension, SIP users or PSTN callers through the Auto Attendant. When the callers reach the extension, a conference call starts. For the first caller calling the Chat Room extension, music will be played unless at least one more participant calls the Chat Room. Voice signals will inform about new participant joining the Chat Room or existing participants leaving. When the number of participants in the Chat Room is 7, no new participants can dial in.
