just to clarify , i'm looking at not impacting our current live system , is this possible? or would i have to register for a trial 3cx system and build one off of that.
If you use your existing license, there will be a little blip where the DNS changes to the new IP. But, this is resolved by restarting the system service (i think its that one) on the live PBX to switch it back.
Otherwise, if you want to stay seperate, create a trial.
