[Freeswitch-users] session.steamFile misses DTMF event for first few seconds

[Anthony Minessale]

12XXX is so many years old, i wish users who want free help would at least
stay up to date with the code.

FYI, our repo is on git now and the svn mirror is not updating at the
moment.

produce a complete minimal script that reproduces your problem and can be
run on git HEAD (see download instructions to learn how to build with git)
Use existing sound files from the FS install so we can just run it in our
lab to reproduce the issue.

Open an issue on http://jira.freeswitch.org and attach the script.
