[OpenSIPS-Users] NAT_Traversal not removing maddr from contact

Hi,

I was using nathelper with fix_nated_contact and have changed over to using
nat_traversal and fix_contact as I am having some other issues with
mediaproxy but found that calls are failing with the apparent difference
being that nathelper removes maddr from the initial INVITE Contact whilst
nat_traversal leaves it intact.

This is causing opensips to route the received PRACK to the maddr private
IP in the contact header and the call to fail.

Is this correct operation for the nat_traversal module and is there another
way to remove the maddr from the contact?

This is with opensips 1.10

Craig
