Re: [sr-dev] [kamailio/kamailio] siptrace: fix tracing messages to database when destination uri not set (#1951)

Yes it works but the code in 5.2 is broken. Here's an example, maybe it's more clear:

sip_trace(); /* traces to database only no db url */ sip_trace("", "$var(correlation_id)"); /* does not work; requires valid duplicate uri */ // with my additions sip_trace("", "$var(correlation_id)", "d"); /* does not work; requires valid duplicate uri */

So there are basically 2 functions: - no arguments - trace to dabase only; - with any kind of arguments - trace to duplicate uri and(if set) to database;
