Look at storing path information with your location data. This can be thought
of like record-routing for registration. Proxies that handle the REGISTER
request are recorded as path data, and then when routing the request the path
can be followed ensuring that the same proxies are traversed.

Subject: [SR-Users] Webrtc connection failure on multiple kamailio server setup

Hi all,
I am running 2 kamailio instances in kubernetes (daemonsets). kamailio act as
webrtc server. all my webrtc clients are registered into kamailio. registration
stored in location table (usrloc).
Issue:
1. Webrtc client registers to kamailio instance-1
2. I am trying to make outbound call and it was initated from kamailio-2
3. kamailio-2 looks up into location table in DB and finds the user
4. However, when it tries to send the call over websocket's tcp, it fails with
the following message
4(197) WARNING: {1 102703821 INVITE 0396e8d0-edae-123e-738c-325f60cc5a45}
<core> [core/msg_translator.c:3036]: via_builder(): TCP/TLS connection (id: 0)
for WebSocket could not be found
Logically this is correct as the instance doesn't aware of the connection
(kamcmd ws.dump does show the connection on kamailio-2 but it is seen in
kamailio-1)
I need help to share this connection details between the instances so that any
kamailio instance can make outbound call regardless of where it was registered.
Thank you for your help in advance.
Maharaja
