Hi Omar,

have you tried to investigated why you get this 404 from the carrier?

The diversion module can only be used to add a new diversion header (something 
that can also be done with textops, for example). The uac_redirect module can 
be used teach kamailio how to handle redirect responses (3XX replies), for 
example for correct accounting and to append them as new branches for later 
relaying. Take a look to the module docs for more information, it contains 
also a cfg example.

Cheers,

Henning
