Which of the following is NOT a feature of 3CX?

Remote desktop access is not a feature of 3CX, which is primarily focused on providing advanced communication solutions. 3CX offers features such as video conferencing options, unified communication capabilities, and call recording functionality that enhance collaboration and improve business communication.

Video conferencing allows users to connect and engage with colleagues or clients through live video meetings, reinforcing remote collaboration. Unified communication features integrate various communication methods like voice, chat, and email into a single platform, streamlining interactions. Call recording functionality enables businesses to record conversations for compliance, training, or quality assurance purposes.

In contrast, remote desktop access is a separate functionality that enables users to connect to and control their computers from a different location, and this is generally provided by other types of software or services. Thus, the absence of remote desktop access within 3CX's offerings distinguishes it from the other features.
