Hello Bogdan and Anca,

Thanks to Anca very much for such good work with the presence
modules. I'm excited to be able to use them correctly (thus my
troubleshooting and questions.)

I know that at least some part of the BLA logic or presence logic
is indeed using the 'received' field, because OpenSIPS is sending
to the correct UAS 1/2 the time. It is equially clear that some
other part of BLA or presence is ignoring the 'received' field.
For each UAS which registers tcpdump shows two SUBSCRIBE messages.
One with the 'received' IP and one with the private IP.

My module parameters for presence and BLA are:

modparam("presence", "server_address", "sip:pres at name.host.tld")
modparam("presence_xml", "force_active", 1)
modparam("pua_bla", "server_address", "sip:pres at name.host.tld")
modparam("pua_bla", "default_domain", "name.host.tld")
modparam("pua_bla", "header_name", "Sender")

...so I'm not setting the 'outbound' parameter it seems, right?

I'm using:

  Solaris 11 x86 (nv-b91)
  OpenSIPS 1.6.0 with TLS

Good question, but I showed you just how I was capturing traffic
to the private IP. You probably missed it, so here it is again:

It's plain old TCP/IP networking. First do a ifconfig to create
a virtual interface with IP, then set a static route,
and finally run software to listen on the TCP socket on the address.
This works as long as I do it on the same machine that OpenSIPS (the
presence modules) are running on.

Any ideas?
