supports conference rooms: every's user dials in the conference room number and can listen and talk to other participants. Access to conference rooms can be protected by a PIN number or open only during specific time windows.

It is no possible to define in advance the proper number of user in a conference, because quality of audio depends on many factors

• the number of participants: every participant can add some noise to the overall call. Despite noise reduction algorithms, both in client and server, it is not possible to completely remove noise. If noise degrades quality, we suggest to temporary mute clients whenever is possible.
• environment noise: some participants can be in silent rooms or on the street. The amount of noise introduced by them is variable. If noise degrades quality, we suggest to temporary mute clients whenever is possible.
• server sizing: server's CPU resources should be sized depending on the number of concurrent calls AND audio codec used. In order to properly size your server according to conferencing requirements, refer to Appendix C - Server Sizing: keep in mind that each participants counts - roughly - as half call. For the sake of clarity, a call with 8 participants have the same load on CPU as 4 concurrent calls.
