[cisco-voip] Inbound dial-peer matching

Mike,

For an FXS port, I believe the inbound dial-peer matching works a bit
differently.  dial-peer 203 is listed first in the configuration with port
0/2/3 so that's what is matched first.  I believe the dial-peer match may
be done as soon as you go off-hook on an FXS port.  You can run some
dial-peer debugs such as "debug voice ccapi inout" or "debug voip dialpeer"
to see this happen.
