  Unfortunately this is mutually exclusive with nathelper. Nathelper
  will rewrite the IP in Contact with the source IP of the packet
  carrying the REGISTER message and user agents will not be able to
  match the Contact in 200 OK and thus update the expires value.

  This has been fixed in the development version of ser. It does not
  rewrite the IP in Contact anymore, the source IP of the REGISTER
  message is stored separately in the user location database.

    Jan.
