[SR-Users] Kamailio on AWS

[Felipe Ramos]

Daniel Thanks a lot for your response, in my case i don't want to provide
so many ips to carriers acl because aws elastic ip are not consistent, that
is the reason i wanted to proxy everything trough kamailio, here it is my
setup
i wont be doing any registration because of my setup does not required it,
on hardware i had kamailio forwarding to freeswitch then distributed to
asterisk and finish to a sbcswitch which i will be virtualizing on aws.

again thanks a lot for your advice you're the best.
