I have an account with econet here
http://voip.econet.co.zw/
I hooked this up with NIMBUZZ. The guys at econet did it for me. Now am not in zim but can do it on my own if i know what to put where. They give you an econet number which will be accessible from anywhere in the world. So basically friends and relatives will be calling me in UK at local rates on my VOIP 0772 number.
I have PIN number, and the voip number
But for past month its not connecting at all. To those in the know what do i put in the fields below:
USERNAME
PASSWORD
DOMAIN
PROXY
