Hi,
Well, if the "message" got to the script level, it means is "looks" like
a SIP message - to reach the script, the message must have a SIP valid
first line and Top most VIA.
So, if your "bogus" messages do not have anything to do with SIP,
considering actions at script level is a non sense as it is too late.
What you can do is to rely on the size of the package in order to drop
it (by default, OpenSIPS drops any UDP packet shorter than 20 bytes -
see MIN_UDP_PACKET in config.h). You can change that value to match your
needs. And recompile.
IF the incoming traffic looks like SIP packages (and it lands in your
script), you should use the sipmsg_validate() to get ready of it asap.
It is not about processing, it is more about avoid polluting the logs
with errors :)

Thats not the case Alex. But I am expecting a large number of UDP
messages arriving on the same port as my udp listening socket.
Just want to be sure there is no wasteful work done parsing such packets.

Are you under the impression that these consume a significant
amount of OpenSIPS resources? If so, how did you arrive at that
conclusion?

Hello,
I am getting UDP (non-SIP) packets on opensips listening port.
How can I
drop those packets to ensure it only consumes the least
opensips resources.
I do have mechanisms to prevent this on the firewall but just
want to be
sure that if such a network packet does reach the server, opensips
doesn't end up parsing it assuming its SIP.
I want to do this without using: sipmsg_validate
