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.


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.

Thanks again to all who responded!
