[OpenSIPS-Users] Opensips.cfg on Amazon EC2 - no audio issues

Dear all.
We have a fairly basic setup on Opensips 3.0 on Amazon EC2. We allow users
to make and receive voice calls only. We are not using any proxy or STUN as
all our calls route completely fine within our country. However, following
are some issues:
1. When we make calls outside our country, there is no audio (both ways).
2. When our users try and make calls between themselves (outside our
country, the calls don't go through at all).
We have tried multiple configurations that we found on github and personal
blogs, however, can't seem to solve this issue - and unable to find someone
who can.
Following is our opensips.cfg file, appreciate if someone can clarify what
is wrong:
#
# OpenSIPS residential configuration script
# by OpenSIPS Solutions <team at opensips-solutions.com>
#
# This script was generated via "make menuconfig", from
# the "Residential" scenario.
# You can enable / disable more features / functionalities by
# re-generating the scenario with different options.#
#
# Please refer to the Core CookBook at:
# https://opensips.org/Resources/DocsCookbooks
# for a explanation of possible statements, functions and parameters.
