[OpenSIPS-Users] error_route not triggering

[Ben Newlin]

Bogdan,

I have increased the logging level to 6, but unfortunately there is only one new log line that is not helpful.

Feb  8 13:37:53 [333] ERROR:core:parse_first_line: bad request first line
Feb  8 13:37:53 [333] ERROR:core:parse_first_line: at line 0 char 17:

Have you been able to successfully trigger an error route in this manner on 2.4.4? Are there any restrictions on where the error route must be defined in the script, e.g. before or after the modules section? I’m just trying to isolate whether it is specific to our implementation and if so, what possible causes exist.

Hi Ben,

There is nothing extra for you to do. The error route should be triggered.

You get this error - https://github.com/OpenSIPS/opensips/blob/master/receive.c#L147<https://github.com/OpenSIPS/opensips/blob/master/receive.c#L147> and if a request, the error route should be triggered (see line 151).

Try to log in debug level, maybe you will get more relevant data.

Regards,

Hi,

I recently noticed some parsing errors in our logs and after digging further I’ve realized that our error route is not triggering when this occurs. Is there some sort of subscribe or attach operation needed to get calls to the error route? The documentation states it will be called automatically. I’ve been able to reproduce the issue in our testbed. We are running OpenSIPS 2.4.4.

My error route is defined like this:

error_route
{
  xlog("L_ALERT", "Error route called!\n");
}

This is what I get from OpenSIPS logs:

Jan 24 21:59:30 [329] ERROR:core:receive_msg: Unable to parse msg received from [203.0.113.4:48096]
Jan 24 21:59:30 [336] ERROR:core:parse_first_line: bad request first line
Jan 24 21:59:30 [336] ERROR:core:parse_first_line: at line 0 char 17:
Jan 24 21:59:30 [336] ERROR:core:parse_first_line: parsed so far: INVITE sip:bad to

My log from the error route is not called.

Any help would be appreciated. I’m probably missing something simple.
