Well, to be honest I'm not exactly sure - it is the 'thing' which the phone
talks RLP to....I'm not sure whether this is the actual base station, or
whether it is something between that and the service providers 'outgoing'
modem bank.  Anyway, I don't mean the server I'm afraid - I'm sure this XID
discussion occurs before your server modem picks up.  Given that you have
mixed success I guess it could well be dependant on the particular base
station you happen to be talking to.
