hello i am on a 3g network and have nettalk however whenever start nettalk up. it says incorrect sip server settings. i have triple checked the nettalk username and password and its correct. under primary codec it has 3 options: G.711u, G.711a and GSM and I chose the first one.it also has an option to enter a prefix whatever that means. Can anyone help me configure and set up nettalk on by blackberrry curve 8520. I would greatly appreciate. Thanks
