Number of Simultaneous Calls?

[Frank86]

How is the number of sim calls tracked by 3CX? We are testing the free one-year standard version of 3CX, which allows 16 sim calls. We ran a test yesterday, with people calling the main line from their cell phones. Once the fifth person called, he got the prompt "the maximum number of lines has been reached, please contact your administrator." So, is it 16 sim calls? Or 4 active calls? Also, do internal calls (extension to extension) count towards the sim call number?

The free license is 16 sim calls.

Internal calls counts toward yours sim calls allowance

What trunks do you have coming into the 3CX system. If sip, check the number of sim calls under the settings, is there a limit placed by your Sip provider

We are using a PRI.

Does an internal call count as one sim call? Or, because it's two internal extensions, does it count as two sim calls?

Does the 3CX dashboard show the real-time number of sim calls?

One to one internal call is one sim call, if user has dial more than one endpoint (conference call), then it is the number of endpoints dialled

Yes, in the middle of the management console, you can see activate calls - Dashboard -> Number of calls in use (click on it, will shown you the call details)

Perfect. Thank you.

Hi Frank86,

Be aware that WAV file can be replaced on the 3CX server, I don't strictly think it is professional people should hear that when making calls.

The WAV file can be replaced with an engagement tone or something like that.

Just replace the file on the server and give it the same name as that of the existing one.

You can also get an email notification sent to your administrator email when your call count is reached.

In the 3CX interface go to:
Settings - Email - Notifications

Please note that you probably reached the maximum calls of the PRI and that's the reason you got the prompt.

A call between 2 extensions is considered as one sim. call.


The 3CX dashboard does not count sim calls that count towards your licence. The active calls tab displays the active legs of a call. For example a call towards a queue will use 2 sim. calls until the call has been answered regardless of agents.
One sim. call is used because the call is actually answered by the queue manager and the other sim. call is used by the queue manager to poll the agents. Once the call is answered by an agent the PBX will use only one sim. call. This is the same even if the queue has 10 agents being polled.
However in the Active calls screen you will see 11 entries displayed, 1 for the call that is waiting inthe queue and 10 for the polling of the 10 agents. Even though those call legs are displayed there they do not count towards the sim. calls of the PBX.
