It depends on your DSL speeds, your compression, and your box.

A good asterisk box (dual xenon 3.6ghz type box) can handle about 120
G729 -> PSTN calls. 120 G729 calls comes out to be around 1 T1s worth of
bandwidth. If g729 -> g729, then asterisk can handle more.

If g711 is used, that is 64K per call so only 24 calls per T1.

Check on the wiki for more comparsions/performance before you shell out $$$
for 3 machines.

But yes, you can use SER to load balance between two asterisk boxes.
