Greetings all, If you know the answer to this, skip everything below: How is the "ID" field used in the 3cxsbc.conf? Is there any plan in the future for this field to behave differently than it currently does? Also any other good tidbits/nuances regarding performance/limitations/potential problems running multiple Debian SBCs would be very appreciated. My versions are: --- I'm trying to mitigate potential problems using w10 for SBCs by migrating all of them to Debian. I've got 2 SBC's up and running fine on the same network (1 Debian SBC for testing and our actual production 3cxSBC on a Windows VM) but I was curious about this ID field. Earlier during setup I modified /etc/3cxsbc.conf on our debian box so that the ID wouldn't be identical to the default one in our 3cxsbc.conf on our Windows SBC (by default it is 123456). The tunnel between the SBC and the 3cx server would not establish, it had these errors (the fqdn and ip have been sanitized): If I set it back to the default ( ID=123456 ) the tunnel establishes and everything works fine. What is this field and how is it used? Thanks!
