I work with a lot of customers doning leased line
aggregation with QOS for voice.  It works well
for them.

Same with ATM PVC's.

Now if you get in to talking about broadband aggregation
in the different PPPoX scenarios we don't recommend you
go with a 75xx.

The one gotcha to be aware of is your limitation will
be the packet switching capacity of the VIP with small
packet sizes.  It's software forwarding only and when
you add features the packet switching numbers will
go down.
