Well, I thought it was implied. If you want to make a call from the A800 you need to either have a phone connected to one of the pbx ports of a800 or a phone line to the pstn port of a800. Then you would make a call using either the phone or calling in from the phone line. Of course you need to configure the a800 to route the call correctly and you want to make sure that the voip phone supports h323.
