Have had a 2talk account for a few years, can't remember why I got it, but reinstalled the software on PC and everything fine, $$ balance still there, installed app CSipSimple in my poor old slow Vodafone 845 Android phone, rang someone in the BOP (I live in Christchurch) as a test and it was good.
So decided to ring my brother in Melbourne and thought it was going to be all broken up and crap, but to my suprise it was loud, crystal clear, it was so clear I was amazed, I was really impressed, call was just after midnight yesterday and about 40min.
I did a speed test (TC cable) on PC to Melbourne via speedtest.net and was 15mb down and 2mb up, same as local except ping was a bit higher.
So i thought VOIP would be not very good, but I was wrong, it was great, all beit only a few calls though, love the way you can walk around and use your smart phone with VOIP if you are in range of wifi.
Cheers
