Nikolay,

I would think we would want both options...

Here in the US there is a need to be able to record incoming & outgoing
without notification for purposes of investigations, but also for companies
to do it as a matter of policy (which usually requires an announcement, but
not always...  if one party of a call knows it is being recorded that is
enough)
