asterisk 12.1.0-1

[LouCypher]

I've followed two different guides on how to setup a LAN PBX using Asterisk. I've configured 3CXPhone, a Cisco IP handset, and Android's dialer to connect, and they all register successfully. My problem comes when I try to make a call. The phones ring, but the call immediately ends.
