I'm not sure I have the right name, but I'm referring to the (new?) service whereby if somebody calls you and you don't get to the phone before it stops ringing, you can just press some code to automatically generate a call back to the person who called you. My question is, does the system filter out any numbers? If somebody from Europe called me, will it dial back an international call for me? What if some slimey 900-type called me? Neither of the above scenarios would be appreciated.

For today, the calling number is available for automatic call-back (I think they call the service Return*Call here in NJ) only on intra-LATA calls between SS7-connected central offices. This limits your liability to the maximum rate for a call within your LATA. 900 numbers only allow inbound calls -- if they called you, then the calling number is not their 900 number but some other number (which may or may not be equipped to receive incoming calls). In the far future, when SS7 connectivity includes the inter-LATA carriers, you'll probably be able to Return*Call places more distant. The best defense, probably, is Caller*ID. It will show you the number you're about to call with Return*Call, if the last call you received was from a properly-connected CO. If the number was not available for display, it probably won't be available for Return*Call, either. Dave Levenson Internet: dave@westmark.com Westmark, Inc.
