Hello, I try to use event_route[core:receive-parse-error] in 4.1.6 event_route[core:receive-parse-error] { xlog("L_WARN", "Event-parse-error: $rm from $avp(inc_carrier)/n$mb/n"); } When core parse error occurs , *log message is not printed*. What is wrong? Thank you, Julia

Hello, iirc, the event route is executed only when the sip request is so broken not to make it till config file execution. In your previous email on this topic that I had in mind to reply but got forgotten, you refer to From. That is not part of the basic parsing (again, iirc), you should catch that using sanity_check() function from sanity module, using it somewhere at the top of config request route (see default config, it is in the route[REQINIT)).

I understand my mistake. It's working when message is broken. I wanted to use it for bad SDP. We have a problem with SDP from some users. In error of parsing SDP on log printed only wrong part of SDP and correlation to call is very difficult.

I see, probably we should add a check in sanity module for sdp. At this moment, I would try to use one of the functions from the SDPOPS module that should not fail normally (e.g., sdp_with_media("audio")) and if there is a failure then handle the error case. Cheers, Daniel
