Firewalls, IP restrictions, etc

Host and Port number

When using an Active connection, it is important to Set the Host and Port number an Active connection (i.e. TIM Plus connects to your 3CX) remember to set the host and port numbers on the 3CX as follows:-

Set the Host and Port number in TIM Plus as instructed below:The host address drop-down contains a list of addresses that your 3CX can bind to.  Choose one that will be accessible by the computer running TIM Plus.  The port is the port that the 3CX will listen for connections on.

In the connection settings of TIM Plus, enter the address that your 3CX is bound to, as well as the same port you configured on your 3CX (above).

Firewall

It is important to open up the firewall port for TIM Plus to establish a connection to your 3CX. If this is not done, you will experience connection issues e.g.

Q. I'm not able to connect the 3CX to TIM Plus. I get the following alert message:-

...

I’m using port 9000 but it's still not connecting. Any tool I can use to troubleshoot this issue?"

A. If you Ensure that any firewalls on the 3CX and on the computer running TIM Plus allow traffic on the selected port.

In order to test whether the connection is working, use `telnet`:

telnet 10.0.0.10 9000

If you don't have the Telnet client on your computer, could you try opening a command prompt and seeing if you get a connection through that?

`telnet 10.0.**.*** 9000`

If Telnet is not installed and you are not able to you can add it through the the Optional Features setting  setting in Windows, there is a tool called .

Failing that, TIM Plus comes with a stand-alone tool name `IPTester.exe` in your `c:\Program Files (x86)\Tri-Line\TIM Plus\` folder .
If you run thatfor testing connections.  Double-click to run it, enter the IP address and port at of your 3CX in the top left and press `Connect`. If it boxes and press 

Let me know how that works out.

Solution: Once the firewall port was opened, the issue was resolved.
