  Well, they need a certain number of trunks to the PSTN. Those are
still sold by the "line". They also need to pay a certain price for each
phone number that they agree to terminate from the PSTN.

  Unlimitel's wholesale rates are $2.50/line, 0.01/minute, assuming the
call is a local call from one of their points of presence.

  The wonderful thing about the new industry is that people are free to
figure out what the right pricing model is.

  a) make sure you have at least one PSTN line, and have a distinctly 
     coloured POTS phone plugged into it with the ringer off. 
     That's your 911 line, and it will work when the power is off.
     You can program Astarisk to ring that line when an extension dials
     911. Whether you use the line for anything else, is up to you.
     Maybe it has your DSL on it, or your fax machine.

  b) you may find that buying different services from different
     providers makes sense.  Don't get locked into a provider that
     does not do SIP, since not all numbers are portable.
