Cool! If I understand correctly if I have a location where a single DSL 
line is insufficient to handle all the calls I could add a DSL line with 
another asterisk box and then distribute the traffic(load) over two DSL 
lines using SER?

This would eliminate the need for expensive 10mit line which exceeds the 
cosf 3-4 DSL lines by far.
