Enterprise video conference services are expensive, though they come with ease of use and implementation, the end-user does not own his data. However, there are many enterprise-grade open source alternatives which come with powerful community support of developers and end-users.
Open source alternatives offer many features and integration more than the commercial ones, as most of those features are demanded by the community and developed with the contribution of the community which makes the open source solution more superior to its commercial alternatives.
