[asterisk-users] Asterisk-beginner : cannot make phonecalls using Asterisk

[Casey Boone]

just for a test, run "service iptables stop" as root on the asterisk 
server and then reboot your phones.  after that, try again and see if 
the phones are making communications with asterisk.

you can turn the firewall back on with "service iptables start"
