You wrote 20 emails on this mailing list for something that is not a problem related to this mailing list while people tried to help you in any form they could.

You have indeed narrowed down to an issue with YOUR Blink install, but that doesn't mean it isn't a network issue or an asterisk issue that only manifests itself in the one software/equipment string. With so many using Blink without an issue, you do understand that it could be anything from other software you have running on your Mac to a setup issue either on the Blink or Asterisk side settings (extension or otherwise) for that particular device? It seems you just keep throwing out the "1500 pound paperweight" emotional comment, as if that is supposed to help narrow down an issue.
