Last time I checked this, it worked as you want only if your SIP Gateways are 
on port 5060.  I was able to differentiate via the host=line, but as soon as 
I used a Gateway on a port other than 5060, Asterisk was not able to match 
the sip.conf entry and it used the default.   I did not open a bug report as 
this was not something we needed at the time.  Give it a try and let me know 
if you see the same thing.
