pbx.c:1755 pbx_extension_helper: No application 'Meetme' for extension (conferences, 1107, 1)
To get around this, navigate to your Asterisk source directory and run 'make menuselect'. This will load a pretty neat curses-based module select menu (a bit like the 'make menuconfig' tool in the linux kernel). At this point, ensure that the meetme extension is selected (ie has an asterisk in the box alongside) and then hit 'x' to save the module requirements and exit.
You should now recompile asterisk with 'make && make install'. You should see meetme in the list of compiled modules as they compile - like this:
[CC] chan_zap.c -> chan_zap.o
[LD] chan_zap.o -> chan_zap.so
make[1]: Nothing to be done for `all'.
[CC] app_flash.c -> app_flash.o
[LD] app_flash.o -> app_flash.so
[CC] app_meetme.c -> app_meetme.o
[LD] app_meetme.o -> app_meetme.so
[CC] app_page.c -> app_page.o
[LD] app_page.o -> app_page.so
[CC] app_zapbarge.c -> app_zapbarge.o
[LD] app_zapbarge.o -> app_zapbarge.so
[CC] app_zapras.c -> app_zapras.o
[LD] app_zapras.o -> app_zapras.so
[CC] app_zapscan.c -> app_zapscan.o
[LD] app_zapscan.o -> app_zapscan.so
[CC] codec_zap.c -> codec_zap.o
[LD] codec_zap.o -> codec_zap.so
So now you should check that you have a load directive in your modules.conf - to ensure that the meetme module gets loaded. This line should be in /etc/asterisk/modules.conf and should look like:
load => app_meetme.so
You are now ready to restart asterisk. The Meetme application should now be available.
