Hello, The Multitech VOIP line supports T38 and I have tested it. It
works great. You will need a public IP to make it work. Very expensive
though. T38 Is not compatible with Asterisk.

I have been on the same path although I am using a TDM400. No matter what I
did I could not get a fax to go through. Yesterday I moved the * server
outside my firewall and the rest of the network and now I am making more
progress. I blame it on old network hardware. I have two accounts, one with
Broadvoice and the other with LiveVoip. The Broadvoice fax is going through
with out any problems. LiveVoip faxing still fails. I would like to use
LiveVoip so I will keep at it.

Hello Mark,
I have been working on a similar plan but am still looking for
reasonable/tested hardware - can you tell me what devices you are
using?
Thanks,

Hi there
I have a SIP ATA with a fax machine attached and a SIP FXO gateway to
the
PSTN. When I try to send faxes in either direction, I get nothing but
stony
silence. I have changed the gateway and the ATA to peer to peer mode to
test
them and they happily do the T.38 thing and faxes flow.
It seems that they initially negotiate a G.729 codec, which is what I
want
and then when the receiving end detects the fax machine, it wants to
re-negotiate and use the t38fax codec. This is the working the Micronet
devices use at least.
When I put the units into proxy mode and run them through Asterisk, they
fail at the negotiation stage.
Now I have learned from my dealings with Asterisk and the newsgroup that
Asterisk does not do T.38. However, why should it not let devices do
T.38?
My debug messages from Asterisk don't show it saying no, but the
gateways
don't wont' setup the T.38 on Asterisk.
I have chanded sip.conf to allow=all and there are no explicit rules in
the
registrations for the gateways.
Does anyone have an idea here?
For this venture to be truly usable, I have to be able to get FAX
working at
this basic level.
Regards
Mark Dutton
