Hello,
I just realized that I quoted the wrong registrar module link (for the IMS) earlier.
Yes, to enable use_domain would be also my next guess. Strange that it does not seems to
work, but the reg_fectch_contacts probably just uses the given string. It probably needs
further digging in the code.
Cheers,
Henning

Hi,
Yes, I learned about the inconsistent behavior between reginfo_handle_notify
and reg_fetch_contacts by going through the debug log and seeing the DB
queries.
I even tried to avoid the problem by changing the Kamailio C code (extract_aor
function in registrar/common.c) and recompiling it, but that doesn't seem
right to me. Both registrar and pua_reginfo appear to be central and widely
used modules, and unlikely to have such a bug. So it has to be a problem with
my config, but I can't seem to spot it. (I have already played with
"use_domain" parameter in usrloc)
Thanks,
Mohammad

Hello,
strange. You probably did already that, but if you activate debug log
level you should be able to also see the database queries that are
executed, just to double check. If might be just a bug in the cfg or possible
also in the code.
Cheers,
Henning
