That's for masochists, surely?

Hi, not sure about dial up, but it works fine with my laptop broadband
card. Im sure it will probably work, but your not going to get the
voice quality you would with a non dial up connection.

I have tried to use skype (although on broadband, not modem as is in your
case) before. But for some reason, the calls drop out after some time. If
we reconnect after the call drops out, then there wont be any sound. It was
pretty weird. I did not have time to debug the issue (one computer uses
windows, the other uses debian Etch). So I started using google talk (which
works only in windows BTW) for voice chat.
I don't know if you are having the same issue. Just wanted to share my
experience.

Ah, I said "for masochists" because it's going to be painfully slow over
a DU account. Skype has (fairly) high bandwidth requirements and
therefore the modem may not be able to cope. The result being dropped
packets, and consequently, the inability to understand what's being
said.
It wasn't a comment on the VoIP technology itself, or the people that
wish to use it. Skype, and similar products, are very useful.
Sorry for the confusion.

The codec Skype uses marginally fits within the bandwidth of a modem
connection. Likewise will speex.
Modem connections also have a relatively high latency. I seem to recal
that the hop of a modem has a delay of some 100ms. This is something you
might even notice. But latency isn't that a problem with VoIP
connections.
A worse problem with VoIP, that tends to accompany latency, is jitter:
how much different packets have different time. An ideal VoIP stream
would have the exact latency and thus no cracks.

I understood what you meant, that it would be a pain to use. I then
made a parallel with Debian being a pain to use. Of course I was only
joking, otherwise I wouldn't be using it.

Ah, I see.
{fx: sounds of penny dropping}
Although, TBH, I find Debian a joy to use. SO much less painful than a
certain proprietary system I could name.

Used to use it, but have little need these days.
