Hello, I'm newbie to Linux/PBX and need someone to help me with setting up the fax with Elastix. I have Elastix installed but FAX is not working. I did everything as per the instructions and tried to follow this forum for help to fix but had no success. Basic PBX function works voice works no issue but when I try to send fax from/to it doesn't. Can someone please guide me to the right direction. Here's my setup. NET -> Router -> Elastix Box (Static IP 192.168.143.xxx) -> IAX Extension is ready and listening -> Virtual FAX is created using IAX Account. Not showing any error. -> SIP Extension connetcted to Linksys PAP2 ATA BOX -> LEXMARK X7350 (Fax Machine) (DHCP IP-same subnet of Elastix Box) -> Linksys SPA942 IP Phone (DHCP IP-same subnet of Elastix Box) 1) How can I verify if all the componants are installed or not? 2) Do I need to setup IAX trunks? (I have IAX extension set as per the documentation) 3) When I do "core show application NVFaxdetect" answer comes back "Application is not registered" While on FAX Web insterface it shows waiting and listening on tty1. Do I need to install NVFax or not? Many-Many thanks in advance.
