My brother in NC always has problems calling me using his MagicJack... my phone might ring but the line is dead when I pick up, or, he gets dead air with my phone not even ringing. Sometimes if he retries 3x or 4x, we'll connect. He has no problem calling others - but they are almost all - all? - using cell phones, so it SEEMS it's a connection-to-copper issue. Anything known about this specific issue? Thanks!
