Hello, i have a question regarding inbound and outbound faxing with 3cx. My Setup: We have two Grandstream HT701 which are connected to printers / fax devices Inbound: I have created two normal extensions with authentication id and password For DID's i created two rules that everything that comes in to the extensions will go to the 3cx fax server. Question: What does "Fax Extension Authentification Password" mean in the fax servet tab ? Do i need this one because i already have two passwords that were created with the extensions Outbound: On both Grandstream Devices i filled in sip user id and the password that 3cx created for the extension. Is this the correct way how to setup inbound an outbound faxing ? What are the menu points FAX Extensions and FXS/DECT for ?
