Thanks for the quick reply. 

How can I fix this? 

When you set t_on_failure for an INVITE, the respective failure route will be executed for
any reply >=0. What you have to do is to not re-route to a new destination from failure
route, simply exit for those reply codes, like: 

if(t_check_status("401|407")) exit; 

You don't handle as well the canceled transactions, when re-routing makes no sense --
you should do it (see default config file for example. 

Cheers,

We are using Kamailio as single point of entry for all our phones. Our phones all
registered with Freeswitch. Kamailio only route the SIP traffic. Is there any way I can
make Kamailio not treat 407 as failure? 

I also have the same problem with REGISTER messages when Freeswitch reply with '401
Unauthorized'. I end up using Forward() instead of t_relay() to make the phone1
register with Freeswitch. 

Any suggestion?

That's because any reply >= 300 is considered a failure.
