Bug#717568: t38modem: Fails to receive faxes if not running as root

[Ramón García]

Package: t38modem
Version: 2.0.0-3
Severity: important

Dear Maintainer,

t38modem failed receving faxes for some misterious reason.

The software registers correctly with the PBX, and the reception
starts. But when making T38
negotiation the process fails.

The problem disappeared when running is as root (the permissions of files
and directories where OK). To isolate this problem, I ran it under strace,
and it worked.

I tried running it under kernel 3.9 from wheezy backports. And it ran correctly,
without any other change.

The logs are not very helpful. When the program fails, the following
is shown in the logs
(running with -tttt)

OpalRTPMediaStream-Source-T.38 -> T38ModemMediaStream-Sink-T.38

this is the error:
Media Patch:0x11084700 PTLIB   recvmsg returned error 111

I am reporting this so that you are aware of the problem. Perhaps the
software should
issue a warning.
