If you have a old style phone - sure, but new cordless phones that I see 
most people having today don't work this way.  They simply measure the 
voltage on the phone line and use their own power (from the normal house 
supply) to generate ringtones, the power for the speaker etc.  They are not 
like old phones where the phone itself draws a significant amount of power 
from the phone line to ring a bell or sound a buzzer.
