Just had a listen then, is that the railway or ambulance? sounds just like it to, even has the number sequence and then with the misterious pause followed by a final digit, (thats another thing I cant figute out).
The recording is definitely Westrail. I have a bunch of Philips gear and I programmed them up to try and figure out how they did that gap is but I never did get it out either. I think it's a Motorolaism as Philips gear can't put a blank space in a selcall sequence. I don't think the radios on the 6DS network did it.
6DS used selcall and ANI. The sequence went something like this:
6DS: "6DS to Warwick. Priority 1 pending" - sends 5 digit selcall number
mobile: - same 5 digit selcall acknowledging
mobile: "6DS, Warwick" - 5 digit ANI
