Hello, I have a 3CX installation running on a dedicated server. We have multiple offices (in multiple countries) and my plan was to have a simple reliable phone system with remote extensions and remote gateways for local lines etc. My question: How do i integrate local PSTN lines into the 3CX server running on the dedicated server? And what equipment do I need to make that happen? In the location where the lines are we have a Grandstream GXW-4108 gateway which is hooked up to another local 3CX box. regards, Frank.
