Ive done everything in all of the tutorials...and ive searched and i havent found anything on this....im using voipraider and yes i have the registrar as sip.voipraider.com and i have the application on my computer installed and have made an account. i have completed a call from my computer to my cell phone, but when i try on the ipod touch i press dial and the button switches to "hangup" and my phone doesnt ring. i tried my cell phone and house phone. i have tried the following input methods of the number 001(area code)(7 digit number) and also just 1(area code)(7 digit number) and last but not least just (area code)(7 digit number). Any help is greatly appreciated.
