Hi Steven,

for the term "rvalue", its somewhat described e.g. here: 
http://en.wikipedia.org/wiki/Value_(computer_science)

The error message probably means that the $g.gw_ip can not compared against 
the to_ip variable.

Do you get also this first error:

 0(8530) : <core> [cfg.y:3396]: parse error in config file sip-
router/test/unit/foo.cfg, line 5, column 6-10: to_ip allowed only in 
onsend_routes
 0(8530) WARNING: <core> [cfg.y:3376]: warning in config file sip-
router/test/unit/foo.cfg, line 5, column 21: non constant rvalue in ip 
comparison

Then i think we know the problem from the first log message. :) If you just 
want to compare against the To domain header, you could use the appropriate 
pseudo-variable or the proper select.

Cheers,

Henning
