To enable the use of the ITU-T T.38 standard for faxing, select yes.
Otherwise, select no.
The default is yes

That statement is a bit vague. What has been put in add-ons so far is
only support for T.38 termination. Not T.38 gateway operation.

Thanks for clarify.. so Asterisk will be able to receive faxes which
comes from a Gateway using t38 but will not be able to relay faxes which
comes from PSTN through a FXO card to other Gateway using t38
can this version of app_fax be used with Asterisk 1.4x ?

T.38 is not a codec. A codec has one input and one output. T.38 is an
interactive protocol. This, however, has nothing to do with what I said.
If you use G.729 in the same asterisk as my spandsp library, you are
breaking my licence conditions.

I should hope
I think you are missing something.
Steve means that since its in add-ons its probably a GPL addition and
not compatible with the g729 licensing.
A t.38 gateway involves more than origination and termination, those 2
are pretty easy and do not involve any modems, the gatewaying is the
harder

About the only reason for eliminating SpanDSP is compatibility with the

Could some one let me know if a fax is received through a FXO card
connected to * and fax machine is connected to a Linksys FXS device
which support T38, is T38 going to be used for faxes which comes from

Not unless you're running CallWeaver or Asterisk 1.6.0-beta4. Asterisk
has had passthrough support for T.38 for a while (somewhere in 1.4 it
became available IIRC) but is currently completely incapable of
terminating or encoding a fax call to T.38.
