Can I program both ports on Linksys PAP2?

I have just installed 1-Voip to my 50 Mbps Internet and it seems to work well. The next step is to disconnect the telco wires and drive the home phones with the Linksys PAP2. This large house has (I think :) ) 6 phones and the PAP2 has a REN of 5 per port.

Can I clone port 1 to port 2 and split the system so that the REN is not exceeded? thanks.
