and why you dont want to have an FQDN on your Server? SSL Certs need this to work correctly also. Therefor we give out Free Domain Names and Certs on them...
We are also wondering the same thing. We have many customers upset when they find out the free edition no longer works with offsite phones after the maintenance expires.
We always try to push the paid versions, but there are some out there who just wont budge. The free one is still worth doing because they eventually grow into a need of a paid version.
So prior versions didn't require a FQDN and I don't remember my last install requiring one so I want to say no. But even if it does, that doesn't mean it has to be a 3CX FQDN.
@StefanW Not that I don't want to have FQDN, but previously we could to do it with the IP address. So, I was wondering if there is any way to do it with the latest version too.
