Virtual Fax Modem via SIP
I'm looking out there for a virtual modem that MS Shared Fax Service can use that would allow the connection to go out through a SIP VoIP. Something simular to SIP TAPI but for faxing
ASKER
I'm looking for an actual plugin, that I guess would create a virtual modem, for Microsoft Shared Fax Services to use to send faxes.
Perhaps one of the following may be suitable for you. he important thing is for T.38 support as sending faxes over normal VoIP is very unreliable due to the compression methods being used.

I think I found a solution. I found two opensource projects (t38modem and com0com) that might solve the issue. But I need someone to compile the code into windows version binaries. Is there anyone out there that can help me. The latest version of t28modem does work with SIP. It can be accessed through cvs. I'm not familiar with accessing the code or compliling it.
I can get the code for you via cvs but I dont have a windows development system to compile it with.

What would I need to complie it?
Not sure but I will be able to tell once I get the source. Do you have a link to a page describing where to get it from?

Here is the web site that allows me to view the directories:
http://openh323.cvs.sourceforge.net/openh323/contrib/t38modem/
I have the complied com0com. I just need the t38modem

You can download the source from :-
http://www.openh323.org/code.html#windows
You will need the windows source for openh323 and the linux source for the t38 modem.
The linux source is in tar.gz format. Winzip will open this archive type with no problems.
According to the readme file you need Microsoft Visual C++ (preferably 2005) to compile for windows.
If you put up a post in https://www.experts-exchange.com/Programming/Editors_IDEs/C_CPP_CS/Visual_CPP/ someone there should be able to compile it for you.

The code there is outdated - very outdated. I've read through a dozen or more web pages that states that the code posted on that site is outdated. It's been noted to get the code from the cvs for the most recent code.

Thank you for your help. I'm now on the quest to get it complied.
If there are any other parts you need in order to compile it and you need the source via cvs just post here again and I will download it for you.

Here is a single page that I founs that summarises the whole thing:

It looks like I also need pwlib and openh323.
It looks like I can get them right from http://www.voxgratia.org.

zcolton,
Were you able to obtain a vritual modem that can use IP TAPI with the proposed solutions once it was compiled?

I never got it to worked. I ended up dropping the whole thing.
maybe take a look at carousel, not sure if it works fuly with the shared fax service, but worth a shot http://www.nch.com.au/carousel/index.html
