you could try smokeping or iperf but real monitoring of the dsl quality 
isnt easy.

we dont run asterisk itself over dsl, but our clients connect over dsl 
to the asterisk server in our housing center.

i dont know sonic wall routers, but sonic wall firewalls are the death 
of voip. every time a customer has used one of these, he got problems 
like call drops, packet loss and so on.

the only way of doing this right, is that the ISP of your dsl lines 
install some kind of QOS for you. If you make this by your own, you will 
only have a one way solution which only helps for outgoing call legs, 
not incoming.

DSL isnt Half duplex as Michael Wilson said, but the frequency used for 
upstream is lower range. Or is it an sdsl connection and not adsl? If 
its sdsl or gshdsl or something like this, the frequencys used are the 
same range for up and download.

the best way to do this is to ask for an QoS for your DSL from your ISP.
