### Cheap night transfers ¶

Your Internet/telephone traffic price can vary, depending on daytime. Night calls/connections could be twice as cheaper. You wish to send your files at that time, but keep high priority email infrequently passing through in anytime. Also you wish to pass any kind of traffic when the node is available through the LAN.

You can easily set your preferences in call configurations for `nncp-caller` command used in online communications.
