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 -- Executing [606@intern:1] NoOp("SIP/105-00000002", "Fax Transmission") in new stack -- Executing [606@intern:2] Set("SIP/105-00000002", "FAXOPT(gateway)=yes") in new stack [Jan 5 00:59:57] WARNING[1831]: res_fax.c:2783 acf_faxopt_write: channel 'SIP/605-00000002' set FAXOPT(gateway) to 'yes' is unhandled! -- Executing [606@intern:3] Dial("SIP/605-00000002", "DAHDI/3") in new stack -- Called DAHDI/3 -- DAHDI/3-1 is ringing -- DAHDI/3-1 is ringing -- DAHDI/3-1 is ringing -- DAHDI/3-1 answered SIP/605-00000002 -- Hanging up on 'DAHDI/3-1' -- Hungup 'DAHDI/3-1' == Spawn extension (intern, 606, 3) exited non-zero on 'SIP/105-00000002' Thanks in advance for any help *José Pablo Méndez *********
