Hi,

I am thinking of developing a voice chat room, maybe with video webcam. How much bandwitch would it use for just voice, single users, multiple users or if I added webcam video.

For each user 24kbps is decent for voice. Video adds a huge load though, obviously...128 kbps is barely acceptable for video.

I need this explained in laymans terms.

am I looking at using more then 10gig a month with it or way more?

Depends on how many users, but probably yes.
