It is a bit hard to tell what is going on because you have blanked the
IP addresses in the config files to all the same value.
If you specify an IP address in the host= line , asterisk will use
the from IP address of a 'new' to try and find a matching entry, and
ignore the username sent in the message.

At a guess you have the IP addresses of  servers 1 or 3  wrong in  
iax.conf on server2
