You are blaming Apple, Blink/Telephone but based on my experience you are on the wrong track.

You need someone technical with experience in IP networks and/or Asterisk to find the cause for your problem at your location.

This mailing list will most likely not be able to help you as the problem has to do with your local network Asterisk setup rather than your computer.
