I won't comment for each one, but the #ifdefs in this file should be looked over
too

[sakal, 2017/05/11 11:06:12]

Do we really need both voice and video for all of these? Please check.

[Zhi Huang, 2017/05/12 20:05:33]

Not really.

[Zhi Huang, 2017/05/12 20:05:34]

Done.

I was being lazy and just replaced all the HAVE_MEDIA with HAVE_VOICE &&
HAVE_VIDEO. :(
