Hi guys, how are you?
I am working with Trixbox 2.6 (Asterisk 1.4.20.1 version) and trying to send faxes with T38.
I have applied next patch http://bugs.digium.com/view.php?id=12931 and I have done next modifications too:
- I have manually created udptl.conf with next lines:
udptlstart=4000
udptlend=4999
T38FaxUdpEC = t38UDPRedundancy
T38FaxMaxDatagram = 400
udptlfecentries = 1
udptlfecspan = 3
- I have added "t38pt_udptl=yes" to /etc/asterisk/sip_general_custom.conf
- For every extension to work with T38 I have configured "canreinvite=yes" and " t38pt_udptl=yes" (really I think all SIP peers are allowed to employ T38 because sip_general_custom.conf parameters are applied for all SIP peers)
- I have added "t38pt_udptl=yes" under [General] flag in sip.conf
After all these operations I can send a fax between two VGs (voice gateway), but I have observed that T38 packets go directly between VGs (not through Trixbox) in fax transmission. But if I perform a call or send a FAX with voice band data, RTP packets go through the Trixbox.
So my question is regarding this issue: Is there any way to get T38 packets go through the Trixbox? I think asterisk 1.6 works in this way (T38 packets go through Trixbox) but I would like to get it with asterisk 1.4
Thanks in advance
