SER module nathelper

nathelper: This is a module to help with NAT traversal. In particular, it helps symmetric UAs that don't advertise they are symmetric and are not able to determine their public address.

  • fix_nated_contact: rewrites Contact header field with request's source address:port pair.
  • fix_nated_sdp adds the active direction indication to SDP (flag 0x01) and updates source IP address too (flag 0x02).
