A month or so ago, I was able to use Openpbx for t38 between a Grandstream
ATA sending a fax to openpbx. Openpbx sending a fax to the ATA didn't work
at the time.
I got busy with other projects and decided to come back to it. I installed a
fresh copy of Ubuntu Server 6.10 used the wiki article for Ubuntu LTS
install guide to install the latest SpanDSP snapshot and then openpbx from
svn. I used the wiki fax page to put in the faxin context into
extensions.conf and enabled t38udptlsupport=yes in sip.conf, enabled
canreinvite=yes. Now when I send a fax from the ATA to Openpbx I get
Apr 13 16:50:07 WARNING[2983635872]: app_rxfax.c:695 rxfax_exec: Could not
answer channel 'SIP/400-a400'
I don't get any traffic when I enable udptl debuging
I'm hoping its a stupid mistake and not a Friday the 13th pitfall.
I'm just using minimal config files till I get things working.
Here are the contents of extensions.conf
[inbound]
exten => 800,1,Goto(faxin,s,1)
[faxin]
exten => s,1,Set(LOCALSTATIONID=Navynet.it FAX)
exten => s,n,Set(LOCALHEADERINFO=Navynet SRL is a solution provider for
business)
exten => s,n,Set(FAXFILE=/tmp/${UNIQUEID}.tif)
exten => s,n,Set(FAXFILENOEXT=/tmp/${UNIQUEID})
exten => s,n,RxFAX(${FAXFILE}|ecm)
exten => s,n,NoOp(RX: REMOTESTATIONID is ${REMOTESTATIONID})
exten => s,n,NoOp(RX: PHASEESTATUS is ${PHASEESTATUS})
sip.conf
[general]
context=default
port=5060
bindaddr=0.0.0.0
srvlookup=yes
t38udptlsupport=yes
[400]
type=friend
context=inbound
host=dynamic
secret=blah
canreinvite=yes
qualify=yes
canreinvite=yes
I want to take as much as I can and place it in the wiki as I learn what
works and what doesn't.
Thanks Steve for working with T38 so much.
