= Engine =

 1. Set User Agent name to blink-version

 1. If '''engine is dead''', the message  '''no sip account is active''' is displayed but is unclear what the real reason is. An engine stop must be logged to general debug window. Not clear how to restart the engine, maybe we should restart the application until a good solution is found

 1. If the engine has stopped (because of some crash) the preferences do not show anymore:

{{{

Blink[26992:10b] <type 'exceptions.AttributeError'>: 'Engine' object has no attribute 'output_devices'

}}}

By setting the wrong TLS certificate files, the middleware does not start anymore:

 1. It seems that the '''stun servers''' are learned from the DNS and cannot be overwritten in settings, they show up automatically
