In my testing of Operator, I'd like to configure a direct connection to another Operator server, so I can test making calls between two separate systems.

I've tried a few different ways to configure it in the Admin Console, but simply can't get it working.

What ports need to be opened through the NAT firewall at each end and what details are required to establish the connection - for instance, is a username and password required for an Operator to Operator connection and if so, where do you define the username and password on the local system that is to be used by the remote system when it connects?

Thank you for this report. We discovered we have a regression bug in generating the "link to another PBX" part of the configuration. This bug will be fixed in the next release.

Meanwhile, you can set up a Operator-to-Operator link by taking the "New provider" path in the wizard for adding SIP interfaces, with some modifications afterwards.

Let's assume we have OperatorA with extensions 11, 12, ..., 19 and OperatorB with extensions 21, 22, ..., 29.

Do the following in OperatorA:
- Open the wizard for adding a new SIP interface
- Enter the interface name "OperatorB"
- Choose the option "New provider", set the external number as "1X"
- In the second screen, enter prefix 2
- In the 3rd screen, set the IP address to OperatorB's address and leave other fields empty (with the exception of the port) and click finish
- Edit the rewriting rules for both incoming and outgoing calls - you should strip nothing and add nothing

Repeat the above steps in OperatorB, with these changes:
- the interface name will be "OperatorA"
- the external number will be "2X"
- the prefix will be "1"
- the IP address will be that of OperatorA

You can try these steps or wait for the fix.
