Many technologies and companies have a presence on the Internet for support and interaction between between users and developers. This model of community support is particularly relevant for RTC technology. RTC, by definition, requires interoperability between all those using the technology and efficient online collaboration helps to identify and resolve interoperability problems. Many users also have common problems to solve, such as the collaboration between Internet companies to eliminate spam.

In the RTC domain, there are a range of online communities with various objectives. The objectives include supporting specific pieces of software, development of standards, discussion of operational issues between providers and advocacy of open standards and private communication.
