Dears,
I have two questions
1-Is there a way to export fax tiff file image from .pcap captured file .
In other words i am trying to backup all faxes that are passing on my
network,and export the fax file later on.
Is this feasible and how .
i am using sip protocol and fax protocol is bypass ,G711 i can use T38 if
that will solve the matter.
2-I tried using asterisk to receive the fax and resend it , but that will
not a real time fax, and if I want to ignore the time ,in case of failed
fax I should inform the user that fax is been failed since the system
received the fax is the first place successfully .
Is there a way to don't hangup the call when the user send the fax first
time to system ?
The procedure is like this .
-User send the fax
-System receive it
-system create a call file
-call file executed and start sending the fax
.
.
-system call the user with prompt Success/Failed

Traditionally people use fax because it's faster than putting a letter in the mail. I don't know why anybody would want slower fax. All I can come up with is you're trying to evade toll charges or otherwise change one expensive call into two cheaper calls. If that's what you want to do, it would be even cheaper to skip the fax, and use the internet to exchange a pdf file between the actual two endpoints. As to whether it's possible? Maybe if instead of the pcap, you do analog fax, record the call, and play back the recording. Maybe that would work?> 2-I tried using asterisk to receive the fax ?and resend it , but that will not a real time ?fax, and if I want >to ignore the time ,in case of failed fax I should inform the user that fax is been failed since the system >received the fax is the first place successfully .If you put a fax machine in the way of another fax machine, it's not going to be real-time. Any kind of arrangement involving two faxes like that is going to be store-and-forward.> Is there a way to don?t hangup the call when ?the user send the fax first time to system ?Yes, but you cannot stop the sending party from hanging up their leg of the call.

It's an open source Windows app that splits out all the info in a packet capture according to content. http://networkminer.sourceforge.net/ You might also be interested Ettercap (http://ettercap.sourceforge.net/).
