I'm a lot less sure based on this reading than you. The machine tells the caller that the call will be recorded. The caller stays on the line. Both parties have just consented to have the call recorded. They have not spoken about the disposition of that recording, but they're fully aware that this is no longer a completely private conversation. As far as I can tell, there's no need for a second consent to have the call recorded on / copied to server 25126B and also server 952C... and so there should also be no need for an additional consent to have the call recorded on the caller's home PC.
