Mmmm. Each connection costs extra money. I'm unsure if one or two minutes are charged per connection attempt, even a failed one. I other words, the phone company charges one minute in advance, minimun.
Just how much are you paying per minute?
I don't exactly know, beacuse the receipt doesn't specify the amount per minute, and how it varies during the day. It's not so easy to find out. But I can give you some samples from this last two month receipt (27.4 Eur + tax in internet calls, 28.7 hours total usage): I have a 4 seconds call charged at .0685 Eur, plus taxes. Another one, 12' 23", 0.1642 Eur. A 1h 12' 32" was charged 1.2903 Eur. It is afordable, but I wouldn't say free. Time is money, even if I'm just waiting without anything downloading. By the way, the fixed or flat rate conection, which would allow me to connect anytime from 18:00 to 8:00 (weekends the 24:00) I think costs about 20 or 30 Eur a month; I'll have to check, but it is even more expensive for my limited use.
When I do that, I must be sure that I't will take me some minutes to fill the form,
I'd have thought you'd have a fair idea of how long your comment will take to enter before you start...
Not if it is the first time I see the form :-)
and that the web page will not reject me on the next phase when it sees a different IP.
Doubt it - your IP could change dynamically while you were sitting filling in the form anyway.
Er... no. During on call the IP can not change. On a new call it certainly changes. The negotiation takes part only at the begining of the call.
Session management isn't usually tied to IP because of DHCP, NAT, etc...
I suppose that web pages keep track of the user by means of cookies, but i can not be completely sure, specially on encrypted pages of banks and such. In such cases I think I would keep track of the IP, and even more, record it in the transaction logs. I'm no expert on that, but that would be my first thought. -- Cheers, Carlos Robinson
