If u are getting the error "No application 'Meetme' for extension "in asterisk console,
do the following . . .
u can make sure that the app_meetme is not installed in ur system by following command on ast console
"CLI > show modules"
goto asterisk source code directory and apply command
"[root@localhost]# make menuselect"
in menu select "applications" and select "app_meetme".
now its time to recompile the ast source code by "make" and "make install" commands.
Good Luck
