@syntaxseed personally, I hate #Videocalls and #ConferenceCalls because EVERY SINGLE ONE I'VE BEEN TO COULD'VE BEEN AN EMAIL AND/OR TICKET INSTEAD!
In terms of noise, yes I've heard a lot of shite over the years, including some disrespectful side-comments which I instantly karma'd by saying: "Back in my days we had the courtesy to use #PushToTalk and keep the finger from the mic button when we talked smack!"
