Interesting, did not know they started monitoring phone calls. Maybe someone from China can try this to see if it actually works?

A Beijing entrepreneur, discussing restaurant choices with his fiancée over their cellphones last week, quoted Queen Gertrudes response to Hamlet: The lady doth protest too much, methinks. The second time he said the word protest, her phone cut off.
He spoke English, but another caller, repeating the same phrase on Monday in Chinese over a different phone, was also cut off in midsentence.
