Google Plus was the first app I used to do conference call with 9 persons at the same time. It was great experience. After that I have been using Skype but the free version has limited options. Recently Whatsapp launched video conference feature that looks good. Video conferencing is always fun provided that you have got strong Internet and that applies to all the participants. I'll check this one for sure. Apparently, it looks good. Good work @urbangladiator.
