A Question About Management/Control Protocol Licensing

I see the following paragraph in the Asterisk trunk LICENSE file:

“In addition, Asterisk implements two management/control protocols: the Asterisk Manager Interface (AMI) and the Asterisk Gateway Interface
(AGI). It is our belief that applications using these protocols to manage or control an Asterisk instance do not have to be licensed under the GPL or a compatible license, as we believe these protocols do not create a ‘derivative work’ as referred to in the GPL. However, should any court or other judiciary body find that these protocols do fall under the terms of the GPL, then we hereby grant you a license to use these protocols in combination with Asterisk in external applications licensed under any license you wish.”

This probably originated some years ago, and I wonder if Digium or the Asterisk community might consider adding the OTHER management/control protocols to this list: ARI, and the ExternalIVR interface.

If not, it might be instructive to learn why!

  • Would also like to see this update to include ARI. We talked a little about it at astridevcon, and I think it is likely an oversight.

  • On Wed, Dec 11, 2013 at 3:15 PM, Paul Belanger It isn’t an oversight. It’s on my ToDo list (and this item is an action item on the wiki as well). We had the Thanksgiving holiday; then I was out last week at AdhearsionConf (great conference!). The licensing file will get updated before 12 is released.

    As an aside, we also had conversations about it on the asterisk-app-dev list [1], where I responded that I would get answers to the licensing questions. Granted, it has been much longer than a week or two – mea culpa on a bad time estimate.
