Hi folks,

I am wondering under what circumstances that openser will generate its
default "477" error response.

I'm still a newbie on the OpenSER software so I hope I am not just
missing some configuration issues.

It seems like its(the 477 responsecode) is for instance used when
transaction layer didnt manage to send the request, and I am a bit
puzzled why the 477 responsecode is used.

According to the rfc, I believe "408 Timeout" would be more correct
on generic transaction timeouts, and on fatal transport errors,
like tcp-reset, I believe 503 is the accurate responsecode.
