I used the instructions from the openpbx wiki,
The system is running Centos 4.4 with kernel 2.6.20.1 compiled with 1000hz
timer and other kernel settings as recommended by Openpbx. Openpbx 1.2RC3,
spandsp 0.0.3pre27. No zaptel hardware is installed although zaptel 1.2.14
and libpri 1.2.4 are compiled and loaded. Hardware is Dell PowerEdge 860
with the Dell Perc SATA RAID controller.
Relevant portion of extensions.conf is:
[inbound]
exten => 800,1,FaxDetect(4000)
exten => 800,n,Hangup()
exten => fax,1,Set(LOCALSTATIONID=FAX)
exten => fax,n,Set(LOCALHEADERINFO=messaging provider)
exten => fax,n,Set(FAXFILE=/tmp/${UNIQUEID}.tif)
exten => fax,n,SipT38SwitchOver()
exten => fax,n,RxFAX(${FAXFILE}|ecm)
exten => fax,n,NoOp(RX: REMOTESTATIONID is ${REMOTESTATIONID})
exten => fax,n,NoOp(RX: PHASEESTATUS is ${PHASEESTATUS})
exten => fax,n,Hangup()
And of sip.conf is:
t38udptlsupport=yes ; Turn on support for T.38 UDPTL
[9590]
nat=never
type=friend
qualify=yes
host=dynamic
dtmfmode=inband
disallow=all
allow=ulaw
allow=alaw
context=inbound
canreinvite=yes
The sending ATA is a Grandstream HT286 running 1.0.7.19
