GNU Gatekeeper 4.8 released

GNU Gatekeeper version 4.8 has been released

This version has many new features. You can download the new version from
https://www.gnugk.org/h323download.html

Overview:

New maintenance mode: When you need to take down your GnuGk server
(eg. for an OS update), you can switch GnuGk to maintenance mode where
it will only allow ongoing calls to finish and automatically redirects
all idle endpoints to an alternate GnuGk server.
The status port command is "MaintenanceMode <alternate IP>".

Detailed information about ongoing calls: You can now display lots of
information about each ongoing call (codecs, bandwidth used, IPs etc.).
The web interface has been extended to to show this information.
See https://www.gnugk.org/images/web7.jpg

Easier installation on AWS and inside docker containers. You can now
let GnuGk automatically detect the public IP of your AWS server, even
from within a docker container. You can also automatically insert your
public/external IP into your trace file names to store logs from many
servers in the same directory.

Extended API: Call routing with external applications has been
expanded. You can now set the display names for participants and
desired reject codes on the status port. You can also access the
vendor information of all registered endpoints. The web interface has
been extended to provide this information, too.

HttpPasswordAuth has been greatly extended to fetch password
information from backend servers. We now use curl to support https
and you can add many new placeholders in your queries.

Extended screening and rewriting of display names and calling party
names.

Important bug fixes: Multiplexed RTP is now much more robust and
password authentication to parent gatekeepers has been fixed. There
are also interop fixes for TCP keep-alives.


Please see the full change log below for more details.
