When creating an extension, make sure that the email address already exist, otherwise if it is not created yet the email will bounce and blocked.1. I am unable to receive emails after I created 2nd & 3rd users.
Using free/smb versions there is not option to use ATA, only supported ip phones and Dects.2. How do i configure ATA adapter to the free hosted 3cx?
There is just option for DECTs in the Voice & Chat Menu3. I do not see ATA/DECT in this free hosted version.

Can 3CX consider adding a short note in the placeholder text, title/tooltip, or under that field? It's easy get the order wrong when adding a new person, and it's not clear 3CX is specific about it until after one hits this issue. For example if the mailbox was created but not added to the spam filter yet, the email will bounce and can't be used for a week.When creating an extension, make sure that the email address already exist, otherwise if it is not created yet the email will bounce and blocked.
Founded in 2005, when VoIP was an emerging technology, 3CX has gone on to establish itself as a global leader in business communications.
