Dial the sip:501xxxx@ekiga.net (where x = any digits from 0 to 9). These rooms are public or private, anyone can join a conference at any time if he chooses the right number or you can protect the access with a PIN number. The first person to enter a 'room' may specify a PIN by entering a number (followed by #) to limit access to the conference room, just entering # will make this conference room public. When the last person leaves a conference room, the PIN will be cancelled and others may use the 'room'.
