Yeah, I've seen Pete's readme and commit.

Honestly I didn't compile it myself, I'm using Ubuntu packages.
I'm on Ubuntu 12.04, but since t38modem package is not available for that distro I manually downloaded packages from 13.10, along with libopal (3.10.10), libpt (2.10.10), libx264 (123.2189).

Debian and Ubuntu still use the old 2.x code, with patches to compile with their current version of opal. 
I'm in debug now, running with:

/usr/bin/t38modem --no-h323 --ptty +/dev/ttyT38-1,+/dev/ttyT38-2,+/dev/ttyT38-3,+/dev/ttyT38-4,+/dev/ttyT38-5,+/dev/ttyT38-99 \
  --sip-listen udp:5060 --route modem:.*=sip:<dn>@10.10.13.13:5070 --route sip:.*=modem:<dn> -t -o /var/log/t38debug.log --sip-audio G.711-uLaw-64k


I tried checking out Pete's sources, but when I try "make opt" it says no rule to make target...
I tried building a ubuntu package with Pete's sources, install it on a test server with ubuntu 12.04, but the issue still persist, the modem remains stuck after the dropped call.
Hylafax config follows:

Further debug raised the following errors, after a modem crashed. I hope it can help to
