What defines an outbound rule in 3CX?

An outbound rule in 3CX is primarily concerned with defining how external calls are routed based on specific criteria. This means that when a user makes a call to an outside line, the outbound rule determines which trunk to use and under what circumstances, such as the dialed number or the time of day. It ensures that calls are handled efficiently and directed appropriately based on the configurations set by the administrator. This routing can include various parameters like call patterns, caller ID manipulation, and priority of different trunks, allowing for tailored call management that aligns with the organization's communication strategy.

The other options pertain to different functionalities within the 3CX system. For instance, call recording relates to capturing and storing conversations for accountability and training, user permissions involve managing the access rights of internal users within the system, and video conferencing is a feature that supports virtual meetings rather than call routing. Understanding this distinction is critical for effectively managing communication in a 3CX environment.
