There is now an auth-plugin which looks for calls matching Emergency dial rules (EmergencyNotify plugin). It currently makes no changes to the message. Could this plugin add a parameter to mark this call as emergency, which sipxbridge could then do something special with? Is an auth-plugin the proper place to do this? What should the parameter look like?
