  Fix an issue where nat=yes would not always take effect for the RTP session on outgoing calls.
  
  If calls were placed using an IP address or hostname the global nat setting was copied over
  but was not set on the RTP session itself. This caused the RTP stack to not perform symmetric RTP
  actions.
