Hi, I'm experiencing the same problem with t38modem and hylafax. My problem is that on the re-Invite phase it syncs lower than 2400 bpps and the connection hangs on the second page.
Could you please post here the patch for asterisk 1.6.2.4 or even indicate which is the trunk of asterisk where this patch take effect? thanks a lot, Miguel Amez. 2010/5/3 Kevin P.
