Hey guys... If I set Call Forwarding on Busy and Call Forwarding on No Answer and then set those off again, will the service return to forwarding calls to the voice mail?

Also, when forwarding the calls, what's the standard? Will the platform forward Calling Number, Called Number, Original Calling Number like in the SS7 ISUP configuration?

I want to forward to an Exchange Server 2007 with unified communication enabled, so knowing

Other question is how flexible can we make the e-mail notification? I'd like to receive e-mail notification on No Answer or Busy, but not for connected calls - currently we receive an e-mail for every call.
