i need a open source video conferencing solution customised to my needs
An example of this is bigbluebutton (dot) org.
LAN version for corporate customers
a. rooms and account management module (including corporate accounts with logo branding etc)
b. Board room video cam view feature....this allows for only video cams to be seen on large screen
c. AD management module that allows adverts to be pushed to certain zones on meeting screens
d. payment module.....invoicing or payment gateway
This a similar to web version but for a specific corporate customer. its installed via .exe or script which will ask for the usual information about customer and allow for some degree of branding for that customer. The license period is set for say 1 year or so and can be extended via the website control panel automatically or by logging into the LAN installation control panel
