Hi! I'm brazilian and I have a I5700L, operator Claro and Android 1.5, 3CXPhone installed via Market. I configured and it registered and received calls, but the audio always output from speaker, low for Earpiece and hight for speaker, and the other person doesn't listen me. Whatever, I can't make calls, I dial the number and I press green phone button, it just doesn't do anything. Can anybody help me? Thanks.
