Asterisk cmd ConfBridge

ConfBridge conferencing bridge  ConfBridge([confno][,options]): Enters the user into a specified ConfBridge conference
ConfBridge is an application for Asterisk starting with the 1.6.2.* series. ConfBridge is very similar in features to MeetMe, but unlike MeetMe, ConfBridge does not perform audio mixing using DAHDI. Instead, audio mixing is performed within the internals of Asterisk.

To get an up2date description of ConfBridge for your used Asterisk version execute "core show application ConfBridge" on the Asterisk CLI.

The option string may contain zero or more of the following characters:
'a' — Set admin mode 'A' — Set marked mode 'c' — Announce user(s) count on joining a conference. 'm' — Set initially muted. 'M' — Enable music on hold when the conference has a single caller. Optionally, specify a musiconhold class to use. If one is not provided, it will use the channel's currently set music class, or 'default' '1' — Do not play message when first person enters 's' — Present menu (user or admin) when '*' is received (send to menu) 'w' — Wait until the marked user enters the conference 'q' — Quiet mode (don't play enter/leave sounds).
The join sound can be set using the 'CONFBRIDGE_JOIN_SOUND' variable and
the leave sound can be set using the 'CONFBRIDGE_LEAVE_SOUND' variable.
These can be unique to the caller.

NOTE: This application will not automatically answer the channel.

When a participant is "muted" this means that the participant's audio is ignored. Nevertheless the muted participant still receives the mixed audio stream. ConfBridge() uses Asterisk's bridging framework which was introduced in Asterisk 1.6.2. There is a common bridging framework in main/bridging.c. The bridging implemenations itself are modules located in bridges/bridge_*.c. There are several implementations with different kind of features. When an application requests a new bridge (e.g. ConfBridge), it has to specify the needed features and the bridging framework will choose the best fitting bridging implementation.
