Hello again,
I think I understand well your network setup now ;)
mhomed=yes (general config option), then it will detect on which interface to send out the message.
mhomed=yes was the final missing bit, and now packets emitted from any interface from SER have a reasonable sender IP address in the packet and payload. This got a call from the SIP phone to the PSTN switch and got a call established (no audio), so 80 points there.
It is an interesting question as to why that isn't the default or at least included in the samples, as it should be harmless on a system with only one interface but would avoid confusion if a system had two or more interfaces, even if one was purely for managament and the other for all SIP/VOIP related communications.
I guess it is a performance issue - there is a little performance penalty introduced, as it needs to open a socket for every outgoing message just to see which socket to use. If you look at ser-oob.cfg mhomed=yes is there (but greyed out).
Now we shall puzzle as to why mediaproxy doesn't seem to have done anything, with the SIP phone and PSTN gateway still trying to send RTP packets direct to one another, something that doesn't work as the two networks don't meet. We will go off and ponder why the proxy addresses didn't get patched into the SIP messages.
good luck!
Stefan
