Can I send/receive faxes with trixbox?
Officially this is not supported although the mechanism to do so is provided within the system. Receiving faxes is pretty simple as it should do it by default if you have FreePBX configured to receive and process the faxes. For sending, you will need to add a product such as Hylafax or AvantFAX, we will be having tutorials on these coming soon. Fax success depends upon the quality of your lines.
