Yes. Basically fix_nated_register() was superseded by the $source_uri 
pseudo-variable, which provides a more flexible and cleaner solution.

nat_traversal is a standalone module designed to supersede both nathelper 
and mediaproxy in matters regarding NAT traversal for SIP signaling, so 
it is fully contained and doesn't need anything from them.
All the functionality related to SIP signaling NAT traversal was already 
moved from mediaproxy into nat_traversal and it remains for nathelper to 
do the same, in the end the nathelper and mediaproxy modules will only do 
NAT traversal for media.
