DHCP server -- "Reservation(active)"

    Looking for a DHCP explanation....

    Using SBS 2003 server, with a separate network for the VOIP phones.

    The old network diagram claims the VOIP phones have a separate DHCP server,
    and are on a separate switch/ BSD router.

    But MOST of the phones are showing up as Address Leases in the SBS DHCP
    management console snap-in,
    But none of the phones are showing up in the DHCP log (enable DHCP audit
    logging)

    But most of those are shown as "Reservation(active)" under lease expiration.

    One phone with a reservation is shown as "Reservation(inactive)"
    Two phones without reservations are shown as "infinite"

    At least one phone is not shown on this list, which seems to indicate that
    this is not the DHCP server used for that network, but if that's the case,
    why are the others 'active'?

    So
    (1) What does "Reservation(active)" mean when shown on an Address Lease?
    (2) What does "Reservation(inactive)" mean? (1 phone)
    (3) How does a phone without a reservation get to be listed as "infinite",
    when the scope specifies 2 days?
    (4) Can an infinite lease be broken?

    I don't want to just delete all this stuff if 'active' means that the
    information is somehow leaking through between the two networks.
