Razvan: thanks again for your time, your message encouraged me to turn
off all the force_send_socket stuff and just try mhomed. This worked,
The problem is that there are multiple problems and so it's hard to
track down what's the main issue. At least now, there are no messages
about failure to send out a socket... but now there are problems still....
Some of these problems seem to be fixed by topology hiding. When I get a
call from an ipv4 ATA I topology hide, and then these ATAs don't see
ipv6 addresses they probably don't understand and then I don't get
messages from them with truncated garbage ip addresses in the request.
on the other hand, somehow doing that broke my SDP rewriting scheme....
so there is more to do, but still some progress. I would like to offer
up an ipv6/ipv4 dual-stacked tutorial for opensips once I've figured it
all out. It would be great if someone would be interested to review that
document for accuracy ;-)
