[VOIPSEC] Security for a home IP phone

[sebastien rittner]

Hi,
  I use a grandstream connected to a router. The provider  is an israeli company. So far, nothing special.
  My concern as a beginner is to know what the chances are that the  account would be hijacked. Also, as a case study, how can someone  maliciously record the data and restore it back to audio? That has been  a question of several customers which I've never been able to answer.
  Thank you for you help.
  
  Sebastien RITTNER.
