Yesterday, something happened—the exact I do not know
just yet. However, when looking at the logging that I have my OpenSER
performing I seen a ton of INVITES, CANCELs, OpenSER became unusable for a time
until I was able to block all SIP traffic at the firewall and let it calm down
enough to restart it.
During this process calls could not be made (in or out). Is
there a way to prevent this type of behavior? It looked as though there were
only a handful of calls that caused a continuous loop. What logic is
recommended to test for a call that has been handled too many times by the
proxy, and to immediately drop it?
Thanks in advance.
