If you can ensure that voice traffic has top priority in all the routers 
between the two sites, there should be no difference in voice quality.  For a 
true point-to-point system this is trivial to achieve, and maximizes the 
bang-for-buck ratio of your interoffice connection.

Obviously having two ADSL connections is not true "point to point" -- you will 
want a leased line, or a dedicated connection to a common provider who has 
the prioritization of voice traffic in your SLA.

You could, in theory, have higher than telco quality voice calls with a VOIP 
system, as you are no longer restricted to 8kHz-sampled, 16-bit audio.  
Naturally the phones must support this for this to work.

If you put a point-to-point DS1 between sites, it's easy.  Asterisk can act as 
a PRI CPE or CO endpoint.
