Yes, calls will almost certainly be routed over mobile networks
instead of BT, probably by using banks of fixed mobile terminals in
CPW (or Opal)s switch (es?), thus losing the CLI as the call is
forwarded via the mobile networks.
You can force CLI presentation on a call by call basis by prefixing
with 1280 (to route via BT) or indeed using the 1xxx code of any
operator which has CLI presentation to mobiles (but you will probably
pay a higher rate!).
