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!
