I did know the way to test EasyDialer. Actually I set my home phone number as Service Number, and 00 as prefix, and dialed my another phone number. When I picked up my home phone, I heard the dialing tones clearly. It worked well!
EasyDialer requires you to allow it access phone functions. Did you deny the permission when EasyDialer pops up for phone access?
Is there any other dialer application on your blackberry? If yes, do you know if the other dialer applicaiton filter or block phone calls?
I'm going to send you an email with more detailed test steps. please check.
