[SR-Users] usrloc extra attributes and db_mode=0

[Patrick Wakano]

Hi Daniel!
I tried the patch, but it didn't work.... After some more debugging I
noticed that actually the problem is in the replication via the dmq_usrloc
module. The Kamailio which receives the registration can access the
attributes despite the DB mode (also it works without your patch). The
problem is that the replicated nodes don't have access to it.
Sorry my first impression was that the location attributes was not working
with DB mode 0, but actually it is the DMQ replication failing to send
contact attributes to other nodes...
I got this in the logs, may be helpful (the serialized data has nothing
related to the xavp...)

I can open a ticket if the problem is confirmed!
Thanks,
