In the context of Outbound Rules, what does a prefix typically indicate?

In the context of Outbound Rules within a telephony system like 3CX, a prefix is a series of digits added to the beginning of a dialed number to identify the route or type of call. This prefix can denote specific characteristics of the call, such as whether it is a local, long-distance, or international call, and it helps the system determine how to handle the routing of the call accordingly.

For instance, different prefixes may route calls through different service providers or apply particular pricing structures, thereby managing call flows based on the type of communication required. By using prefixes, organizations can optimize their telephony expenses and ensure that calls are routed over the most appropriate channels to suit their needs.

The other options do not accurately represent the function of a prefix in this context, as a prefix is not associated with the call status type, duration, or priority level, but rather the route type or area the call is intended for.
