- RAS messages can be forwarded to other gatekeepers
- TCP parameters can be configured in the config file

  that are replaced by another E.164 number
- many bug fixes...

- support for gateways: for gateways we only compare the prefix of
  the E.164 address the gateway registered and assume that the gateway
  provides access to the whole address space (needs testing!)
  input from Frank Breitenbach
