If you find the same problem with multiple ITSP's, then it may not be
them that is at fault.

Sounds like it should be quite adequate... how many simultaneous calls
are you doing?

What time is that for your local time? Is there something that might be
happening at/around that time for you? eg, here, around 3 - 6pm is quite
busy as school kids get home and go on the internet, same for people
getting home from work. In fact, my vague recollection is that things
just get busier until around 11pm, before they really slow down.

While this doesn't have any relation to *your* adsl connection, think
about what this might be doing to your ISP's internet connection....

Not that I would know, but I get the feeling that most people get
extremely good quality calls over a decent internet connection.

I've not used any, so can't comment on this.
