Google for "sipvicious" (automated program that attempts to find
destinations that are not secure in order to make calls) for more
information.

Options->Network settings:
  Check "Random" for both SIP/UDP & SIP/TCP

Restart Linphone to remove fixed ports & use random ports.

I haven't seen a single "ghost" call in many months since setting these.
