[SR-Users] Setup dmq_usrloc

[Gertjan Wolzak]

Hello Kamailions, 

Im trying to setup registration replication with the use of the dmq and dmq_usrlog modules. 

I have configured two servers, configured kamailio on both. 

When I register a sip client on the one I get a nice KDMQ message on the second server, but the second server reacts with a 404 not found:

I think I have to configure a bit more than just the parameters of the dmq and dqm_usrloc modules. 
Ive googled, looked in the Sip routing with kamailio book, but no luck. 
Did not see any examples in the kamailio source, with regards to the dmq_usrloc module. 

I am not looking for direct answers, have not provided you with enough information for that, but I would appreciate information on how to correctly configure registration replication using the dmq/dmq_usrloc module... 

Thank you. 
With regards, 

Gertjan
