<div class="moz-text-html" lang="x-baltic">Hi there.<br>
I have the similar problem ("Digium fax - sending fax call file vs
manager originate") sending faxes with Asterisk 1.6.2.6
and Digium res_fax. Receiving is OK.<br>
I use Local channel in Call file and context [fax-out] in dialplan.<br>
<br>
My setup: Asterix<-SIP (T.38)-> Cisco(MERA MSIP
v.1.0.2)<-> LocalTelco<->fax machine<br>
<br>
Debian GNU/Linux 5.0 ; Linux 2.6.26-2-686 #1 SMP i686 GNU/Linux<br>
Asterisk 1.6.2.6<br>
<br>
sip.conf<br>
[TG-out]<br>

host=193.110.9.17<br>
insecure=port,invite<br>
disallow=all<br>
allow=alaw<br>
t38pt_udptl = yes,fec,maxdatagram=400<br>
t38pt_rtp=no<br>

exten => start,n,SetCDRUserField(${LOCALSTATIONID})<br>
;exten => start,n,ResetCDR(w)<br>
exten => start,n,Hangup()<br>
etc.<br>
<br>
Problem in short is as following: <br>

Asterisk reply with TRYING and then launches sendFax() and then I get
error.<br>
