Hello Everyone,
I'm having an issue with lookup() and save() when handling WebRTC traffic.
I need to send the SIP response back to my client, but this client uses an
instance ID that isn’t fixed — it changes between browsers and sessions.
I’ve been trying to save the location using a custom URI, like this:
xlog("L_INFO", "Instance ID: $fn\n");
save("location", "0x00", "sip:[email protected]");
and for lookup I’m using a simple:
lookup("location");
but get this error:
lookup failed: Location lookup failed for user:
894aa72f-d7a3-437b-ac20-62b3943f7b5e
I’ve checked the module docs here but I’m still unclear on how the lookup
process works internally or what’s missing in my configuration.:
https://kamailio.org/docs/modules/4.2.x/modules/registrar.html#registrar.f.lookup
Here are my my logs:

Any ideas on how to make lookup() find the right record or how to properly
handle this dynamic instance ID scenario for WebRTC clients?
Thank you.
