[Q] How to enable modules/channels to compile

I have noticed some asterisk channels are disabled by default and am aware of the reason(s) why such a module/channel isn’t enabled by default. I tried to enable the channel through make menuselect; however, it is listed with XXX. As such, the compilation process skips such a module/channel. Does anyone know which file(s) I need to edit to enable the modules/channels by default? This way, I can create a patch. Thanks.

When highlighting something that shows as XXXX on bottom it will tell you what package you need for it to work.
