Hi Daniel,
Thanks for your advice.
I uncomment #!define WITH_AUTH and now mslio is working fine.
However, some UA sent two REGISTER when connecting to Kamailio,
and it turned to be the result that the offline messages were dumped for
twice.
I tried to use if(registered("location")) to detect that whether it is the
initial register but failed.
registered("location") always returns false.
Before , when using OpenSips,
registered("location","$avp(s:fu)","$ci")
works fine.
But at that time ,no NAT support at all.
Any idea for this issue??
Thank you very much.

Hello,
can you watch all network interfaces with ngrep and see if the messages are
relayed? It may happen that they are looped due to the address in r-uri and
then challenged for authentication. If so, then allow all requests from your
server ip/port without authentication.
Cheers,
Daniel

Hi list,
I have Kamailio running behind NAT. (Amazon EC2)
When I use mslio module, storing messages for offline contact is working
fine,
however the stored messages are never sent to the contacts when they get
online.
My configuration is as below.
Any kind of help will be great appreciated.
Thank you!
