[SR-Users] Calling a user registered on a different kamailio

[Joey Golan]

 Hi Daniel,

Yes, the TLS connection is terminated to kamailio.
I can have multiple kamailio instances (not limited to two).

I managed to get some progress and establish the call but the ACK is not
reaching its destination.
I attached a PNG that shows the sequence and what I'm doing in kamailio.
any help would be appreciated.

Thanks
Joey.

Hello,

if tls connection from client is terminated to Kamailio, then a phone can
be reachable only via the Kamailio that accepted its connection. You can
add local path to the registration and then enable:

*
https://www.kamailio.org/docs/modules/stable/modules/registrar.html#registrar.p.path_check_local

Now, just some different ideas to explore: if you just have only two
Kamailio systems and do not expect more, you can skip replication and just
route to the other Kamailio if lookup() location returns false for traffic
coming from endpoints. If traffic is coming from the other Kamailio, return
404. This works fine and can be simpler approach if there is a single phone
per user account. In case there can be many phones per user account, then
after lookup location add a branch with the address of the other Kamailio.

Cheers,
Daniel

Hello,

I’m trying to make a call between 2 users registered (TLS) on two different
kamailio instances behind haproxy with NAT handling.

UE1 is registered to kamailio1
UE2 is registered to kamailio2

DMQ and dmq_usrloc are enabled so each kamailio can see all registered
users.

What else do I need to do in order to make it work properly?

Thanks,

Joey.
