You are not meant to use the 'phone' port at all.  That port is simply
hard-wired to the 'line' port to allow you to connect an "emergency use"
phone.  This phone will always have access to the line - even if the
server/power fails.  Using the 'phone' port will not lock the 'line'
port.

You could replace one of the X100Ps with a Sipura SPA-3000, which comes
with one FXO and one FXS.  You should be able to plug your modem into the
FXS port and dial out via the FXO (in theory).
