4PSA develop and sell a software suite called VoipNow Professional (version 2.5) which, amongst other things, includes it's own packaged copy of Kamailio. This version is derived from Kamailio version 1.5.4.
The software installs a binary release from a 4PSA repository. The RPM information contains the following:
# rpm -qi voipnow-kamailio-1.5.4-130312.41.rhel5
Name : voipnow-kamailio Relocations: (not relocatable) Version : 1.5.4 Vendor: Rack-Soft, Inc devel@4psa.com Release : 130312.41.rhel5 Build Date: Tue 12 Mar 2013 18:31:30 EST Install Date: Sun 02 Feb 2014 00:15:14 EST Build Host: rhel5-1.64b.build.4psa.ro Group : System Environment/Daemons Source RPM: voipnow-kamailio-1.5.4-130312.41.rhel5.src.rpm Size : 6599403 License: GPL Signature : RSA/SHA1, Tue 12 Mar 2013 18:35:28 EST, Key ID 42ba8c472f75de11 Packager : Rack-Soft, Inc devel@4psa.com URL : http://kamailio.org/ Summary : Kamailio, a very fast and flexible SIP Proxy
I've made a direct request to 4PSA for the source code for this package, only to be told they don't release their sources. The request, and subsequent response, can be found at http://my.4psa.com/4psa/topics/where_can_i_find_the_source_code_for_the_voi pnow_2_5_x_modified_version_of_kamailio.
For those interested, the following packages are included with VoipNow which are derived from GPL software. There is no source available for any of these from the vendor.
# rpm -qa |grep voipnow voipnow-spandsp-0.0.6-100708.10.rhel5 voipnow-asterisk-1.6.1.20-130312.07.rhel5 voipnow-asterisk-addons-1.6.1-130131.30.rhel5 voipnow-php-2.5.5-130312.11.rhel5 voipnow-sox-14.3.1-100723.30.rhel5 voipnow-asterisk-sounds-1.4.22-100723.25.rhel5 voipnow-kamailio-1.5.4-130312.41.rhel5 voipnow-ejabberd-2.1.4-100723.29.rhel5 voipnow-asterisk-debuginfo-1.6.1.20-120417.09.rhel5 voipnow-asterisk-extra-2.5.5-130312.11.rhel5
My requests are falling on deaf ears. Does anybody know how to make them take this matter seriously?

Hello,
we have been discussion on management groups since this morning to understand the issue and see what can be done. However, it seems that a link to the sources has been published in the forum pointed by the link in the email. Perhaps that closes this specific case.
Anyhow, for sake of getting some clarifications for the future ...
Starting with the remark that none of us are lawyers, so we recommend that everyone in a similar situation should seek professional advice, the GPL sets the contraint of distributing the source code along with binaries between a vendor/person (let's say entity) using GPL software and its clients. If the binaries are made public to everyone via open web/ftp/etc servers, my personal understanding is that source code should be made available as well or at least upon request by interested people. If the binaries were purchase and were accessible only via some commercial relation, only the one that purchased the binaries is entitled to ask for source code.
Kamailio project itself can assist by testifying it is indeed a GPLv2 software (if needed, being something public is easy to check), but I don't think it can enforce it or get in between two foreign entities, without any relation to the developers holding GPL copyright. Again, my understanding.
To anyone being interested to read more, here are some links that could be useful (thanks to the people in the management groups of the project that pointed them to me): - http://gpl-violations.org - https://www.gnu.org/licenses/gpl-violation.en.html
Also, if somebody has remarks or links to related resource to contribute, please do it, they can be valuable for everyone in the community.
We hope that everyone out there will play honest and follow GPL rules, so it will be no need for complex actions by any of the users of Kamailio project. It is an open collaboration environment and we aim for a fair ecosystem.
Cheers, Daniel

My understanding is that it is OK to add proprietary value to kamailio with configuration files as long as source code of kamailio binary and its modules are made available to those who use the software.

Thanks everyone for the assistance here. It looks like the source code does contain a considerable amount of extra code (for reference see misc_4psa.c within the package downloadable at http://www.4psa.com/software/kamailio-1.5.4-4psa.tar.gz).
