Ok, ok not always but pretty much with the right
conditions you wouldn't notice any difference to a traditional landline
You need equipment set up right and you need a
good internet connection to get the best sound quality. With this in place
the quality is fantastic.
With things not quite so perfect you may
experience some echo on the line, ie you can hear yourself speak, it can
be a bit disconcerting.
In all cases you will pretty much get a better
reception than a mobile phone (cell phone)
