Many people have questions about what license they will need when buying a 3CX system. There is confusion in the market regarding what constitutes or occupies a call license. When it comes to a 3CX license, a Call can be classified as the following 1) Any inbound call to an IVR, Ring Group, Queue or Extension 2) Any outbound calls 3) A Call between two extensions (each party is using a license during a this type of call) 4) A Parked call 5) A Call to a conference bridge There is no “time out” function on parked calls. Once the call is in a parking orbit, it will stay there until it is answered or the call is terminated. By using the 3CX SLA Function or the 3CX call assistant you can monitor actively parked calls.
