I’m trying to get `drouting` module working for REGISTER. But seems it’s not passing one of internal checks, cause in REGISTER R-URI does not contains username and I’m getting errors

drouting [drouting.c:567]: build_ruri(): stripping 0 makes username <> null

drouting [drouting.c:970]: do_routing(): failed to build ruri

So, as I got, this module is mainly for calls (means INVITE) routing, rather than to use it like one more dispatcher, or it’s also a way to handle this part here?
