Hello,

I am a newer on asterisk. when I tried to send fax, I can not get success. After doing a lot of reseach, I decide to ask my question at here.

Instead of using old fax machine, I want my system can send fax via t.38. Could anyone give me some idea to correct my configuration?

Thanks a lot!
Here is the detail:

my system: *ubuntu 14.04 + asterisk 11.7*

I use apt-get to install the ubuntu default version of asterisk 11.7. for easy debug, I just change a few param value with the default version sip.conf

t38pt_udptl = yes,redundancy,maxdatagram@0
faxdetect = yes

extension.conf

[sendFAX]
exten => s,1,VERBOSE(sending fax…)
exten => s,n,Set(FAXOPT(headerinfo)
