There seems to be this strange story going around about how 43-22 should be blocked from outside Austria while 43-1 is allowed and both forms designate the same phone if dialed inside Austria. This is false! Please check the web site www.sauerhof.at which is one of the hotels in the famous resort town near Vienna of Baden bei Wien. It clearly shows that their telephone number is +43 2252 412510. I have found others of this form. The "22" following the country code for Austria is not invalid or to be blocked by anyone. It is the first part of a perfectly good 4-digit city code. If there is some other local dialing plan in Vienna or Austria that uses "22" for some other purpose, it can not appear in a conflicting position in the dialing string and can not be confused with being a part of the international or national number. On the other hand, if such a code is used in the local dialing plan for some special purpose, SIP must figure out a way to handle it. But don't treat it as a part of the subscribers number.
