  You probably had the Realm attribute set to the string "~\^\(.+\)\\.telco$".  Which mean that string matching worked.

  Or, someone made local patches to the server.

  Perhaps you could explain the goal, instead of talking about a particular solution.

  You could put the regular expression into unlang, and then go from there:

	if (Realm =~ /^(.+)\.telco$/) {
		update request {
			My-Filter-Realm := "DEFAULT"
	else {
		update request {
			My-Filter-Realm := "%{Realm}"

  Then add My-Filter-Realm to raddb/dictionary as a "string" attribute.  And make the attr_filter module key off of My-Filter-Realm instead of Realm.
