[SR-Users] Use of received=X.X.X.X param in Contact header of REGISTER message

Hi all,

I have an existing Kamailio installation that is handling registrations and
NAT traversal for clients.

There is one particular build of softphone that sends us a received=X.X.X.X
param in its REGISTER message and it seems that the current Kamailio's
config in place always uses that address to store the AOR.

It happens to be that the client appears to be misbehaving and sending an
outdated IP address on that field.

My question is where in the NAT traversal functions do I have control over
using this param or not.
