The file is located in the /etc/asterisk/ directory.

Meetme is used for conference calls. In this configuration file a conference room that you want to use has to be declared.

This configuration file is read every time you call app meetme() and Asterisk should not be restarted or reloaded in order to see the changes made in this configuration file.

[rooms]
;Context where conference rooms have to be declared.

Syntax is like: conf => confno[,pin][,adminpin].


Example:
conf => 1357
;This will create conference room 1357 open for everybody who can enter the context in the dialplan it will be accessible.
conf => 1111,9938
;This is conference room 1111 with pasword for authentication at log in 9938. No admin password.
conf => 2222,1821,191871
;This room number 2222 prompts for password on login 1821 and password for administration 191871.

In the dialplan the application looks like MeetMe(confno, [options]) where the available options are one or more of the following (do not use separator if you need more than one option):

'm' -- set monitor only mode (user can only hear the audio, not participate)
'p' -- allow user to exit the conference by pressing '#'
't' -- set talk only mode, user won't be able to hear
'v' -- video mode
'q' -- quiet mode (don't play enter/leave sounds)
'd' -- dynamically add conference
'M' -- enable music on hold when the conference has a single caller
'b' -- run AGI script specified in ${MEETME_AGI_BACKGROUND}.
Default is conf-background.agi (Zap channels only, does not work with non-Zap channels in the same conference)

Note: In order to have a working MeetMe conference you need a timing source (ztdummy).
