Hi folks,

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

if the proxy fails at transport layer to forward the requests

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.

is not at transaction, but transport layer.

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.

408 Timeout is timeout at SIP level - there was no response (final) received for the sent request. Here is the case where the request was not even sent out.

Or?
