    Is T.38 (Fax over IP or SIP) supported?

    As of Asterisk 1.6.0.6 T.38 is supported and is included in Asterisk. However we recommend that you use 1.6.2 as earlier versions had problems.
     

    Do I need a Digium card in order to install Noojee Fax?

    No.
    If you are going to be using T.38 (Fax over IP) then NO you don't need a Digium (or any other) telephony card.
     

    I'm using a SIP provider (ITSP) to make calls, can I also use them to send/receive faxes?

    Yes.
    Provided that your ITSP supports T.38 then yes you can send/receive faxes over SIP.
     

    Can I send faxes over a IAX trunk?

    No.
    You must use SIP or a PSTN (analog or ISDN) trunk.
     

    Can Noojee Fax convert MS-Word and other email attachments and send them as a fax?

    Yes.
    Noojee Fax supports a large number of file formats and its fairly easy to add additional attachment types via an external xml configuration file (NoojeeFax.xml).

    Can I use SpanDSP with Noojee Fax?

    Yes.
    We however don't recommend using SpanDSP if you are reselling a fax solution to a third party.
    SpanDSP is simply not reliable when it comes to sending large or high density (lots of black) faxes.
    We have also had a number of incidents with it crashing Asterisk.
    If you are using it for your own personal faxing purposes or just the occasional fax then SpanDSP is fine.

    The open source version does not support the Digium Fax for Asterisk drivers at this stage.

    How do I purge the queue?

    Sometimes incoming or outgoing faxes can get left in the queue without hope (or maybe desire) for them to be delivered.

    To remove these from the queue, just delete the associated files from the spool directory and then restart Noojee Fax:

    rm /var/spool/njfax/incoming/* /var/spool/njfax/outbox/* /var/spool/njfax/spool/* /var/spool/njfax/tmp/*
    /etc/init.d/njfax restart
