Syntax: SF [ <call> | all ]

Starts forwarding to <call>. <call> may be a S&F partner or a user S&F call.
You may only use this command for testing purpose, because the S&F connect is
normally done automatically. If a connection to <call> exists, command is
ignored. With "sf all" you can start forward daemon, this means a connect to
all S&F partners are being started.
