iptables -A INPUT -s YOUR_HOST -i ETHERNET_CARD -d PBX_SERVER -p TCP -j 
ACCEPT
iptables -A INPUT -s YOUR_HOST -i ETHERNET_CARD -d PBX_SERVER -p UDP -j 
ACCEPT
iptables -A INPUT -s PBX_SERVER -i ETHERNET_CARD -d YOUR_HOST -p TCP -j 
REJECT
iptables -A INPUT -s PBX_SERVER -i ETHERNET_CARD -d YOUR_HOST -p UDP -j 
REJECT
