Next day after setting my configuration I start getting calls from numbers like "1000" or "10000". After a search on Google I found that these are "SIP scanners" calls. One of the methods to block this is to set X_AccessList on my OBI to only allow calls from a number of IP addresses. I can not find anywhere a list for Freephoneline, can you provide one ? Thanks. Try to use method 3 from here:
