SIP trunk

[Qly]

Hello,

I am looking to connect 4 3CX servers to another server that hosts the trunk.
This trunk has 4 DIDs, 1 for each "final" 3CX server, and I need to be able to make outgoing and incoming calls from each final server via these DIDs.

Has anyone ever done any type of setup?
If yes, is it possible to help me?

I thought of bridging my 4 servers with the server that hosts the trunk, but I cannot do a DID on the master which redirects to a slave's extension.
I can provide more details if needed.

Thank you in advance for your help.

Adrien

Look at bridging your servers - https://www.3cx.com/docs/manual/connecting-pbx-bridges/

I tried with a master-slave bridge, but I cannot redirect DDI from the master to a slave's extension.
Also, all the configuration is setup on the master, and the slave cannot really owns his DDI rules.

Or maybe there is a solution with this kind of bridge ?

You can send the call to an External Number and then type in your extension from the bridged PBX.

I think since each PBX has a dedicated DID, you should consider finding a way to assign those DIDs as separate trunks. This will allow you to fully use the power and flexibility of each PBX independently
