PAT] Well, I attempted the following: 1) I originated a call to a friend; 2) I flashed the line, got the three beeps, and a dial tone. I then dialed another friend; 3) After I said "Hello", I flashed the line so we were all connected and started to chat; 4) I picked up LINE 2 in my house, and dialed my number, BUSY! So, I placed another call to Bell of PA. I explained again my situation, receiving a CW tone during a three way call. The agent looked into some book she had, and explained to me that I live in an area with a "5E" switching system, in which CW and 3WC can have NO interaction. Whereas my friend who lives in a different area has a "1A" switching system, where they DO interact! Now, those two numbers I only put down from memory, so I may be wrong. The only thing I have noticed different between my system and his is that when he gets a CW and I am online, I hear a CLICK, and when I get a CW, the person on the phone with me gets one second of silence. Also interesting is that on his system, if he calls me three way, and in the middle of the call he gets a CW, when he switches to that CW line, I can actually keep talking to the other party! It is a pain that my line is busy during 3WC, because I ordered CW for the specific reason of NOT loosing calls! Are there any specific questions I should ask the phone company, or just give up on this one? Michael Israeli izzy@netaxs.com [TELECOM Digest Editor's Note: Give up on it then.

Anyone know? and Pat replied that it depends on whether the 3WC is established or is in the third-party consultation phase when the incoming call arrives as to whether or not it will invoke CW. Most switches can be configured to either allow or disallow CW during a 3WC *after* all parties in the 3WC are connected. I once had CW & 3WC from a 1A, and I could get a CW beep during a 3WC. My friends served from the 5E in the next town could not. I doubt that any mere mortals could get Bell of PA to enable it. ;-) Mike mk@tfs.com ------------------------------ Date: Fri, 14 Jan 94 13:00:41 EST From: Ron Schnell Subject: Re: Call Waiting/Three-Way Together > [TELECOM Digest Editor's Note: There are two types of 'three-way' calls. > If you are in 'consultation' you have pressed the hook, dialed a number > and are talking with a third person while leaving the second person on > hold.

The reason a busy signal has to be We have been through this before, I thought. Most switches will *not* allow you to get call waiting during the three-way call. Of all of the places where I travel during the year, only one allows the call waiting, and that is in Miami, FL. My friend down the road who is in a different CO cannot use it. I remember someone saying that it is enabled by default on 1ESS, but not 5ESS. This was about a year ago in this group.

Gee, and > DTMF tone generators are so hard to come by. The only thing I can think of that could make that statement true is that it is apparently possible to design the telephone hardware to block the DTMF frequencies coming through the handset. I had an AT&T phone and a Commodore VIC-20 modem some many years ago. The phone was one of the first with the "limited-travel" buttons on the keypad, around 1982. The modem plugged into the handset cord and sent DTMF tones down the wire to dial, using your base unit phone for everything else. On the old phone I had, it worked fine, but on the AT&T phone, it wouldn't even break dialtone. I called AT&T and they told me that they had deliberately designed the phone not to allow DTMF through the handset, although they steadfastly refused to say why. I don't have any tech specs on this point, and in fact no longer own that phone, so I can't tell you anything beyond that.

So the genuine NYNEX phones are rotary, and the drug dealers will go across the street to the touch tone phones which are owned by COCOTS and the other 'rip-off' companies. It will be interesting to see which group of crooks succeeds in stealing the most from the other. [Note to the humor impaired: that was sarcasm, with a touch of bemused irony.] Bart Z.

They are (I think) in Parsippany, NJ. PAT] My wife's business uses a card referred to as Watson. I called the company for some specifics (it came bundled with some software) and they told me at the time that they have products that will support four lines and you can have multiple cards per system. Unfortunately I don't recall the name of the company or the exact city -- Boston suburb, I think. If you send me a note via E'mail I'll dig up the information at home this evening and respond to your note privately. Overall, I'd say that we're pleased with the product. I've made modifications to the incoming routing routines and found that programming the card was very easy. The vendor states that there is a company in Canada that sells a 'C' library for custom applications -- something I'd very much like to get my hands on! David L.

I sent them a credit card number over a month ago, and though I have not yet heard back from them, there have been no unauthorized charges to my account. 2. There is, in fact, a WHOIS listing for iia.org, and it is possible to telnet to the address (I believe it's mary.iia.org). 3. I have heard a report of at least one person (friend of a user of my server, panix.com) who has gotten connected with an account.

I did so, and they advised me that I am being put into the system, and that I will receive my "Welcome Aboard" packet in about two weeks.

Date: 14 Jan 1994 17:34:30 -0800 Organization: ROLM - A Siemens Company If you have an American Express card, it's easy. You call MCI (I think Sprint also has a similar deal), and they'll setup an account where they bill your Amex card. In the US, there's an 800-extender for long distance. When I was in Austria last year, I had no problem using MCI's service there to call an 800 number here (I don't know what carrier the recipient used.) The call just showed up on next month's Amex bill. BTW, using the MCI service was substantially cheaper than the Austrian PTT, about $1.30/minute vs $1.80/minute for the same call.
