My in-laws BT line is number-withheld by default. They use, I think, 18866 for their calls. They always come through to us as "INTERNATIONAL" on the caller-id ! Might be another route to try.
I use 18185 a lot and one of my relatives uses 1899 (both from the same Finarea group as 18866). To be honest anyone using 18866 or 1899 and not using 18185 should switch over to it as its mobile rate of 6p per minute is far lower than the other two and there no counterveiling higher charges in other areas.
In any event my experience is that calls routed via this carrier may be presented to other callers in any of the following conditions:-
1. Full UK format CLI is presented
2. International version of UK CLI (commences 00441xxx on the display) is presented
3. Unavailable is displayed
Which of these CLI conditions is presented depends entirely on which call carrier Finarea routes that particular call through and that varies with the time of day etc and not just the actuall number being called.
In any event none of this any longer makes any difference with hardened NTS revenue sharers like the London 2012 Olympics ticket line or Santander since even if you withhold your number or use 18185 to make the call they have all now updated their systems so that the call is still flagged up to them as having been made through their geographic alternative overseas number by a UK originated caller and consequently they still reject it and play you a message to call the 084 number instead.
I got through to the London 2012 ticket line on their 01 number using 18185 several months ago but now they always reject my call to that number using 18185 no matter how many times I call.
