Path doesn’t share registrations. It just allows routing from B back through A in order to reach the endpoint, rather than trying to reach the endpoint directly. It’s just a header that says “when contacting this registrant, hop/detour through the original registrant”.

But, Path doesn’t do anything else. So, if you want registrar B to know that the registrant is registered anywhere at all — A or B — and the Contact/URI at which to reach it (whether directly or through a Path hop), you need some means of replicating the registration database. dmq_usrloc provides this aspect.

Path and dmq_usrloc do entirely different things, of different degrees of significance to the overall process. The “heavy” part is done by usrloc/dmq_usrloc.

Hello,

If I have to use path protocol or other routing logic to share REGISTER between the Two Kamailio so I can call From USERA on KamailioA to USERB on KamailioB, I think I don't need to still use DMQ_USRLOC module.

Can you offer a practical use of this module, please?

Thank you

Regards

To replicate knowledge of the registration contact bindings automatically.

It doesn’t provide magic routing to reach them. It just shares the knowledge. :-)

If I have to use Path or other solution, which is the main idea behind the DMQ_USRLOC module?

Yes, you need the Path module and special logic for lateral routing of requests received from A and transiting through a Path hop of B.

Hello,

I'm testing DMQ_USRLOC modulo between two Kamailio servers (A) and (B)

The two servers share the same domain and using Amazon Route53 to distributes 50% requests each Server.

The problem is when I try to make a call from user A (registered on kamailio A) and the user B (registered on Kamailio B).

The call follow this flow:

User A --> KamailioA --> UserB

go directly to userB because KamailioA know, via DMQ_USRLOC IP and port of UserB. With some Softphone the call work with audio without problem; with other Softphone USERB never answer the INVITE sends from Kamailio. Is it possible use this flow?

USER A --> KamailioA --> KamailioB --> User B

to resolve this kind of problem or is there other available option?

Thank you
