Aloha, We are looking to roll a solution that will have the following network layout: ISDN-PRI <--> Asterisk <--> T.38 <--> ATA <--> Fax Does version 1.8 with the Digium fax driver have this capability? I like 1.8 because it is a long term support version. What ATA's are people using? Any working solutions would be great! Aloha, Matt

[asterisk-users] Anyone have a reliable T.38 Solution
I'm using the Linksys PAP2T and the Grandstream with SpanDSP and tx_fax and
rx_fax on multiple installations with no problems.

Aloha,
We are looking to roll a solution that will have the following network layout:
ISDN-PRI <--> Asterisk <--> T.38 <--> ATA <--> Fax
Does version 1.8 with the Digium fax driver have this capability? I like 1.8
because it is a long term support version.
What ATA's are people using?
Any working solutions would be great!
Aloha,
Matt

Asterisk 10 does, and it is supported using SpanDSP and res_fax_spandsp. It is not yet supported by Digium's Fax for Asterisk commercial FAX module. -- Kevin P.

The PRI-port is connected to the telco, one of the ISDN-BRI ports is connected to an old Fritz!Box Fon http://www.avm.de/en/Produkte/FRITZBox/FRITZ_Box_Fon/index.php which has 3 (newer ones only 2) analog ports. The calls are routed by the bero*fixBox to either the asterisk server or the hylafax server based on the DID number. The bero*fix box has ~30 softmodems that translate to T.38-SIP which is then connected to the t38modem on the hylafax server which handles around 70,000 faxpages a month. Outgoing (incoming only for test purposes) faxes from our analog fax machines are routed by our asterisk server back to the bero*fix box so we achive bit-slip-free (and therefore reliable) connection. Beronet also has PCI- and PCIe-cards to be directly installed in your asterisk server. Frank
