Call quality is very similar to the above products. However, most of our community partners and collaborators are not aware of FreeConference and are thus less able to utilize it without prompting and sometimes assistance from us.
I selected freeconferences.com at the time because I didn't have access to my webex account and I was crunched for time . I was a bit amazed/"Taken back" as i wondered why this wasn't protocol already. The platform is easy, free, a no-brainer.
