I thought there was some talk of getting T38Gateway into asterisk_addons? Stupid linking bullshits.

I'm surprised T.38 support isn't a higher priority for Digium, given that faxing has such a high failure rate with VoIP.

[asterisk-users] T.38 Faxing and Asterisk
I understand that Asterisk 1.4 should support T.38 pass-through, but I need Asterisk (or something on the Asterisk box) to act as a T.38 endpoint. Judging from the unclaimed $12,000USD bounty, it doesn't appear that Asterisk itself can do this. http://www.voip-info.org/wiki-Asterisk+T.38+Bounty Does anyone have any experience with this, or are able to point to an example of this working? It looks like I need something along the lines of Asterisk detecting an incoming fax, passing it to IAXmodem (or something, I don't know what could do it) for conversion to T.38, and then the T.38 getting passed on to an appropriate T.38 supporting ATA (or other endpoint). Or at least I think that's what we need to support these scenarios. Scenario 1: 1. Somebody sends us a fax, and is an analog signal until it gets into the Telco's network where it is translated to digital audio. 2. The call comes in over our T1 to our Asterisk box. 3. Asterisk box answers and converts the incoming digital audio fax into T.38 data. 4. Asterisk box contacts an ATA that supports T.38 (such as the Grandstream HT502) and sends it the T.38 data. 5. The ATA converts the T.38 data into an analog fax signal for an attached fax machine. Scenario 2: 1. Somebody sends us a fax, and is an analog signal until it gets into the Telco's network where it is translated to digital audio. 2. The call comes in over our T1 to our Asterisk box#1. 3. Asterisk box#1 answers and converts the incoming digital audio fax into T.38 data. 4. Asterisk box#1 sends Asterisk box#2 the T.38 data over a relatively slow/high latency connection. 5. Asterisk box#2 contacts an ATA that supports T.38 and sends it the T.38 data. 6. The ATA converts the T.38 data into an analog fax signal for an attached fax machine. Scenario 3: 1. Our fax machine sends a fax out over an analog line attached to an ATA that supports T.38. 2. The ATA converts the fax over analog signal to T.38 data. 3. The ATA sends the T.38 data to Asterisk box. 4. Asterisk box converts the T.38 to fax over analog and sends the digital audio out over the T1. 5. At the other end of the Telco's network the digital audio is converted to analog and a fax machine receives the fax. Scenario 4: 1. Somebody sends us a fax, and is an analog signal until it gets into the Telco's network where it is translated to digital audio. 2. The call comes in over our T1 to our Asterisk box. 3. Asterisk box answers and converts the incoming digital audio fax into T.38 data. 4. Asterisk box contacts a system running sipX with a SIP over UDP connection and sends it the T.38 data. 5. sipX contacts an Exchange 2007 Unified Messaging box and sends it the T.38 data. 6. Exchange 2007 converts the T.38 data to an image in an email and stores it in the user's inbox within Exchange.
