Assuming anything is on the second pair is risky, since the phone company has used all number of things on the line from power to special local hacks. If the idea of accidentally shorting a second line bothers you, use a 100 ohm resistor in the loop. This should be innocous even if the modified phone was plugged into a two line jack. -Ron
