For giggles, go to ANY airport bathroom and see how many are on their cell phone taking a conference call and few have it on mute...You hear groans and moans and you wonder.....I just have to chuckle how many of us really don't use more common sense when it comes to conference calls. I always MUTE my phone whenever I am on. I usually will email the team and say, hey I'm traveling but will be on the call and on mute. No worries on my end...

They get an email and for me it is a simple CYA.
