Basically it works like having ISDN dialup with a lot of bonding. When
asterisk notices more than X lines idle, it dials up the other side and
sends it off to ZapRAS to bond the channels in. If asterisk notices less
than X channels free, it disconnects one of the ZapRAS channels.
Bandwidth is then in units of 64K connections.
