終於成工從 obi202->freepbx->comnet 收發fax 了!
關建在於 canreinvite=yes 或 comment-out。因為obi202 同freepbx 要轉fax mode (t.38) 時,canreinvite=no,所以obi drop line!
我的freepbx trunk setting 如下:
username=85235021234
type=friend
t38pt_udptl=yes,fec,maxdatagram=400
secret=3268xxxx
realm=85235021234
qualify=yes
port=5060
jbenable=no
insecure=port,invite
host=202.0.179.3
fromuser=85235021234
fromdomain=202.0.179.3
faxdetect=yes
dtmfmode=rfc2833
disallow=all
;directmedia=no
context=from-trunk
;canreinvite=no
allow=ulaw&alaw |
