Does anyone have a working asterisk 1.8.4 configuration and ITSP provider that they can recommend? We have been trying T.38 DIDs from our current ITSP, but we have been unable to make it work. I am more than happy to purchase new DIDs from a different provider if they will consistently work and are fairly priced.

Thanks for the suggestion Anthony.

I went ahead and signed up for a free DID from http://www.ipcomms.net/, but am still unable to receive faxes sent to that DID into FaxForAsterisk.

I have tried faxing to the DID from 2 different fax machines connected to different POTS lines. One fax machine is a Xerox Workcentre, and the other is a Brother Intellifax. Can you provide some more information about your setup? If you wouldn’t mind sharing your sip.conf settings, and maybe any other FaxForAsterisk related dialplan settings I would be greatly appreciative. I feel like we must have *something* really stupid set incorrectly. The faxes usually attempt to send, and appear to be properly switching to T.38, but usually end up failing with a “receive partial”. We are currently using the Digium fax driver, but have also tried it with spandsp.

I am open to any suggestions on resolving these issues. Thanks for any help you might be able to give!
