This is what the Advanced server mode is for.
Standard (I avoid this at all costs. No FF and Team VOIP? I’d rather go to a Custom, than this!)
Friendly Fire: off.
Fire Team voip: on.
Team voip: off.
Global voip: off.
Advanced (best choice)
FF: on.
FT voip: on.
Team voip: on.
Global voip: Not sure about this one (anyone knows?), but I recommend turning it on. Gaming is a social event! (But if it indeed is turned off by default, changing it might switch your mode to Custom. You don’t want this as you will alienate the team players. If you do, make sure that you mention in your server name that this is an Advanced mode server, with additional global voip enabled. But this might not even work as some filter for Advanced.)
Oldskool (my personal favorite.)
FF: on.
FT voip: on.
Team voip: on.
Global voip: on.
If you recieve any harrasment, you always have possibilities to a) local mute offender (everyone can always do this), b) vote mute offender (depends), c) kick offender (vote/admins) and d) ban offenders (admins.)
Btw. all this only means it is enabled on the SERVERS. The clients still have all I/O voip disabled by default. (Big Mistake SD :stroggtapir: You found the perfect way in ETQW, why change that? But at least there’s a visual indicator, so perhaps the mistake is not that big after all.)
