Interesting. What part of the stanard states that? From what I can see in 
EN 300 403-1 RESTART is allowed in both directions. Clause 5.5.1 in that 
standard states 
  "A RESTART message is sent by the network or user in order to return 
   channels or interfaces to the idle condition."

We do not use the idle restart ourselves. It should not be needed and may 
do harm (is there a race where the remote end sends a SETUP at the same 
time Asterisk sends a RESTART?).
