  • full traversal zone support (gatekeeper-to-gatekeeper H.460.18 / H.460.19)
  • RTP multiplexing (all calls to and from devices supporting H.460.19 will only use 2 sockets total)

  • notifications when GnuGk opens listen ports
  • rewrite destination IPs into aliases
  • ENUM, SRV and RDS routing policies extended for LRQs, in case the calling gatekeeper isn't able to do this
