Summary:                    Can not using T.38 origination with app_fax/spandsp
Description: 
I tried to send a Fax from the first Asterisk (Asterisk1) to the second
Asterisk (Asterisk2). When Asterisk1 initiates an INVITE with CODEC G.711.
Asterisk2 accepts this INVITE. Immediately, Asterisk2 sends a RE-INVITE
with T.38 SDP. However Asterisk1 responds it with "488 not acceptable
here". 

So, Asterisk1 sends a Fax with G.711 instead of T.38.

I can confirm that SendFax works properly in latest with T38.  Been
struggling with it all day and just got it working.
