SpanDSP error codes

SpanDSP provides the core functionallity within Asterisk for sending and recieving faxes.
If you are using trixbox then you don't need to worry about SpanDSP as it is included in the base install.

If however you have installed Asterisk 1.2 (or earlier) then you are going to have to rebuild Asterisk to include SpanDSP.
We don't recommend this for the novice, you need to a fairly competent Linux Sys Admin before I would suggest you undertake this task.

In reality there is no reason not to use trixbox as it contains all of the functionality of Asterisk plus more.
We strongly recommend you install trixbox.

Having said that; if you still want to install Asterisk then the following explains the process for adding SpanDSP functionality.

AsterFax™ is a trade mark of Asterisk I.T..
I'm not a great believer in Trade Marking Open Source software but unfortunately someone has been running a scam to redirect traffic to a bogus AsterFax web site. As such I've trade marked AsterFax's name to provide protection from such people.
