I am lookign for the enterprise version of a conference calling app that can be used among for a large number of people, but it cost effective as well. The packages being offered by apps like Mobileday and Speek are just not feasible.
Also, someone recently recommended me with an app called MeetingMogul offering enterprise version at an extremely affordable cost. If someone has relevant information about this app please do let me know. You can download app from: www.meetingmogulapp.com
