Since 3CX STD Edition is now free, the option custom FQDN is no more available. We have prospective customers who do not wish to to renew maintenance and also donot want to lose their fqdn where the system will stop working and losing web meeting access. lets say web meeting access will lose, but all stun provision, remote phone will not work, I understand the 4sc STD edition is free, but In perpetual licence (Which is mot free) should allow customer to use their own FQDN. Please Advise. Thank You.
