Bug#887480: t38modem: Fails fo hangup after non-fax incoming call

[Alexey Lobanov]

Package: t38modem
Version: 2.0.0-4
Severity: important

Dear Maintainer,

After upgrade from Wheezy to Jessie our production fax receiving system based on
t38modem and hylafax stopped to work. Modem never hangups after non-fax incoming calls.
Faxgetty forced restart resurrects the modem until next incoming call.

Downgrading t38modem binary to Wheezy version 2.0.0 together with 
libpt.so.2.10.4 and libopal.so.3.10.4 in /usr/local/lib solved the problem completely.

The problem seems to be mentioned also at
