Even if you found that this wasn't correctly detected, generally
it is quite normal to check and use username in h_To as something
another than username in RURI. It can be used, for example, to
select specific DID number across the pool assigned to the
customer specified in RURI (this is used e.g. in Sipura/Linksys
SPA9000 as one possible form of such DID specification). See also
ISUP specs and draft-yu-tel-url: they specify special "routing
number" which also can be passed, in different tradition, in RURI
(while final number is passed in h_To).
