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

  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 '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.
