Cotroneo) Subject: GSM Tariffs in Europe Date: 25 Jul 1994 14:04:05 -0500 Organization: UTexas Mail-to-News Gateway I had the opportunity to play around with a new GSM phone last weekend, and was amazed by the features offered by this service, some real, some still non-implemented (e.g. call forward). I travelled by car from Milano, Italy, to Genova, and then West to the border with France on the Italian riviera. I had almost everywhere good coverage on the motorway and over the coast. Coverage appeared to be everywhere on the road the same as for the other analogue (900 MHz, TACS) cellular phone. To my surprise at the place of my stay some 15 km from the French border, I realized that with the GSM phone I had the option of using one of THREE (!) available networks (one Italian and two French). [US readers please do not laugh: phones in Europe are still a monopoly in most countries :<( ] As soon as I realized that I could make a call to France via one of the the French telephone networks, thus bypassing the Italian operator, I tried to find out more about the different rates, and rate systems, used by the different GSM operators. Unfortunately, after calling the Italian operator "SIP" on 119, they suggested that I placed an Int'l paid call to each operator to get their tariffs (They gladly provided me with their numbers in Paris, good only during business hours Mon-Fri). This makes quite difficult and expensive to get a clear picture, and e.g. select the best operator in countries where more than one exists (e.g. France, Germany, UK, etc.). If not supplied already, it would be helpful to the European GSM owners if anyone could point out which are the current tariffs for long distance and international calls when roaming in European countries served by the GSM system, or at least provide the respective GSM operators' toll free assitance number, which may be called when entering a new network. How could one decide which operator to use? Maybe stopping at the first telephone boot when crossing the border and have a look at the telephone directory? I would probably have to stop at each operatr's telephone boot, which makes it most annoying especially when you travel on motorways ;<) . I will be glad to pass on any information on rates you may subject when roaming thru the Italian SIP operator. Or you may call toll free 119 when you switch to the SIP network in Italy. Any help will be gladly appreciated, and if there's enough interest I will be glad to summarize. Please reply directly since I may not read the news from here. I also found most annoying to try calling Italy from France by dialling 0039-XXXXX, and then today back at home I learned from my telephone directory that in France you get access to the international lines by dialing 19-39-XXXXXX; the situation is -- sadly -- all the same non standard and most confusing when you dial e.g. from Austria: 00-40-XXXXX, Spain: 07-39-XXXXXX, the UK: 010-39-XXXXX, or Norway: 095-39-XXXXXXX). It's not a mistype, Austria disregards completely Italy's country code by making it 40 instead of 39. Alfredo E.

Marketing representatives from the company persist in calling me despite several requests to be put on the do-not-call list. I know that the 1991 Telephone Consumer Protection Act makes it illegal in certain circumstances to persist in that manner. I have also heard of at least one successful action in a Small Claims Court under this act -- that case involved telemarketing on behalf of Citibank as I recall. Does anyone know of other cases, preferably involving telephone companies? The issue hinges on a "prior business relationship" existing between the caller and the recipient. If the marketer opens the call with a personal discussion on a topic specific to the recipient, that might change the situation. So, "Hi, I'm calling to confirm that we received your last month's payment of $47.23, and now let me introduce our new plan ..." could supposedly be construed merely as "good customer relations"! Any leads on specific cases would be much appreciated. Thanks, John Murray, Universoty of Michigan [TELECOM Digest Editor's Note: Why not just drop them as a carrier and go with someone else, and let them know why you are dropping them.

McKeough) Subject: Who and Where is Northwestern Bell Organization: University of Massachusetts, Amherst Today's newspaper included an insert from a retailer advertising a trimline-style phone manufactured by Northwestern Bell. While the ad included the Bell System logo (now the RBOC logo), the name didn't ring any bells with me. I don't remember seeing the name on a list of AT&T's former operating companies, but then I've been mistaken before. Is this company out in Pac*Tel or US West territory? Canada, maybe?

It basiclly is a classified Ad system running on the Dialogic 4 port cards. I commissioned a company to write it using the VOS operating system as supplied by PARITY software in the US. It was very expensive to develop. However it has just come to my notice that I might have saved myself a considerable amount of time and expense if I had used a system called RING which is a GUI based development system. I would like to "talk" to somebody who has experience with this system. I have seen the demo of RING but I would like to chat with somebody who has used it to develop an application. Also I am looking to source it directly from the company that makes it can anybody give me a clue where the company is based? Please e-mail me with any information you may have. Thank you for taking the time to read this. Kind regards, Chas Watkins Sydney Australia. ------------------------------ From: maridai@comm.mot.com (Marida Ignacio) Subject: Voice-Activated Call Organization: trunking_fixed Date: Mon, 25 Jul 1994 14:00:19 GMT Hi.
