[OpenSER-Users] Server Crash - Sending 500

[Kelvin Williams]

While simulating a database failure (stopping the service), I noticed that
OpenSER would also crash (see log below).  While I don't mind the OpenSER
crash since in our configuration its highly dependent upon the database,
what I would like to do is send a 5xx series message to the client so that
it would be forced to look at one of our other proxies to complete its call.
As the client continued to send the INVITE to the original server.

 

How can I send a 500 Server Internal Error message back to the client in the
event of a database failure?
