We have, in the past, received patches on the issue tracker that were
implementations of Broadsoft functionality that the patch contributors
did not have the copyright for. Even if you have obtained sufficient
permission from Broadsoft to implement such a feature for your own
Asterisk system, such patches are not acceptable for general inclusion
in the Asterisk project without written permission from Broadsoft
stating that they approve the of the patch's inclusion, subject to the
license contributor agreement.

This is an unmoderated, public mailing list. While you may be choosing
to simply ask for assistance about a patch you have personally
written, and were never planning on contributing said feature back to
the project, I personally would not suggest discussing this work here
further unless Broadsoft has licensed you to do so.
