[Q] Custom ROM without GAPPS topic

Hi guys,

I want to remove all Google's components. I installed Paranoid 4.4 BETA 4 without any GAPPS, every works. Network, i can send and receive SMS, 4G is avaible, no fc's etc etc.... But when i try to call someone via the Kitkat Dialer ( 4.4.2 Nexus 5 ), calls hangs up immediately and nobody can call me...!

What should I do to receive and issue calls ???

Thanks you in advance
Regards, Loris
