[asterisk-users] Incoming Fax Issue with Asterisk 11.7 and Digium Fax

Hi, im using a Asterisk Server which is not behind NAT.
First i had problems with the fax detection. But this is now solved 
after adding a wait(2) at the correct place. But i'm still unable to 
receive a fax due to res_rtp_asterisk.c:3548 ast_rtp_read: RTP Read too 
short after the Fax session has started.

Do you want to keep your received faxes or is it OK to overwrite them 
the next time asterisk is re-started!?

You may want to change

use_even_ports=yes

You will need to restart Asterisk for this change.

Some other suggestion if the above doesn't help are;

faxdetect=cng
t38pt_udptl=no
