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:
xlog("L_ALERT", "Error route called!\n");
This is what I get from OpenSIPS logs:
Jan 24 21:59:30  ERROR:core:receive_msg: Unable to parse msg received from [203.0.113.4:48096]
Jan 24 21:59:30  ERROR:core:parse_first_line: bad request first line

Jan 24 21:59:30  ERROR:core:parse_msg: message=<INVITE sip:bad to syntax\r\firstname.lastname@example.org:5060;transport=UDP;user=phone SIP/2.0
My log from the error route is not called.
Any help would be appreciated. I’m probably missing something simple.
