Hello,
Trying to set up res_fax_spandsp. Based on
https://wiki.asterisk.org/wiki/display/AST/T.38+Fax+Gateway I wrote this in
my extensions.conf:
exten => 306,1,NoOp(Fax transmission)
same => n,Set(FAXOPT(gateway)=yes)
same => n,Dial(DAHDI/3) ----->FXS port to fax machine
same => n,Hangup()
Call flow Im trying to pull out is as follows:
Zoiper --> Asterisk with TDM410 --> FXS --> Analog fax machine
I am totally lost about the use of this new gateway module in the dialplan.
I think it loads ok:
CLI> fax show capabilities
Registered FAX Technology Modules:
Type : Spandsp
Description : Spandsp FAX Driver
Capabilities : SEND RECEIVE T.38 G.711
1 registered modules
Also I have the FFA manual, which I couldn't understand. I think FAXOPT is
common to both, but still not sure how to put them together. Where can I
find documentation about configuring the call flow described?
Or some insight will also be appreciated.
Here is my sip peer config:
[105](headquarters) ;zoiper phone
type=friend
secret=
mailbox=105@default
t38pt_udptl = yes
Dahdi:
;FXS Modules
group = 2
signalling = fxo_ks
context = interno
channel = 3-4
faxdetect = both
Finally, a verbose output:
== Using SIP RTP CoS mark 5

Thanks in advance for any help
