OK I give up.
Being not buggered up my self by the seemingly small minded and normal to your location local providers of communication (phone and internet) and efforts by the state controlled provider to control all access to communication; I would suggest that you look at the wider picture.
Control and monitoring of the standard land and satellite phone lines is easy; the internet is not so easy, hence communication over the WWW is open and requires a degree of expertise and cooperation by the high players to maintain an overall and effective monitoring control.
Hence control and restrict internet based communication is an easy option. Restrict and control, I have monitored (And early on added some ideas) this Thread for some time and the classic trends are showing, monitor communication (this thread as one) respond with countermeasures, you chaps are not going to win using standard commercial fixes.
Sorry but that’s a fact of life, I would suggest that a more lateral method of thinking was adopted.
Outhouse.
