The sip.conf.sample file and the voip-info wiki has all the information you need to try it out. Correct. However it would be helpful to note T.38 support in Asterisk is broken. Take a T.38 ITSP, T.38 enabled Asterisk and T.38 ATA and try to send a fax. It won't work! We do this in our testing all the time, and it works fine. Since you didn't specify any particular version of Asterisk, there's no way to associate your "It won't work" statement with anything in particular. Given the variations of T.38 implementations that exist in ATAs, carrier networks and other places, *any* T.38 connection that involves implementations from more than one vendor is (unfortunately) likely to have problems, whether any version of Asterisk is involved or not well I tried a linksys spa 8000 and 2102 thru asterisk 1.8.3 1.8.4 1.6.2.16-19 sonus switch at itsp (012 israel) and no luck
We'd be happy to investigate why it failed, if you can capture the packet streams on both sides of Asterisk. Frequently, it's a configuration issue in at least one of the devices in the system.
