I haven't had a landline in about 4 years (known as "naked" ADSL - there's no dialtone on my copper line). I played with VOIP for quite a while but could never really get the quality I wanted.

Hangouts and Skype solved my international phone call problems, although I'm not entirely sure how they solved the echo/delay problems so well. Edit: oh, right, this was an SMS specific article.
