Can you confirm whether you have a firewall between the phones or not? And also using tcpdump and IAX debug what packets you are seeing

This is a network problem and something is disrupting the return packets so you need to see where it's occurring 

From the cli use the iax2 set debug command and watch what's happening. Are the packets being returned? If they aren't check with tcpdump to see if they are at least getting to your interface

Do the same at the other end to work out whats missing
