Or that you are not receiving any packets.

Enabling SIP debugging in Asterisk can yield clues.

`sudo tcpdump -i any -s 0 -v port 5060` can yield more clues. Note that 
tcpdump sees packets before iptables and Asterisk sees packets after 
iptables.

If you're getting packets, sngrep and wireshark can yield even more clues.
