         Specific permission is also granted to link Asterisk
         with OpenSSL, OpenH323 UniMRCP, and/or the UW IMAP
         Toolkit and distribute the resulting binary files.

      <p>
         In addition, Asterisk implements several management/control protocols.
         This includes the Asterisk Manager Interface (AMI), the Asterisk
         Gateway Interface (AGI), and the Asterisk REST Interface (ARI).
         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 &apos;derivative work&apos; 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.
