[OpenSIPS-Users] Configure file for opensips 3.4

Thu Sep 14 20:46:26 UTC 2023

After reading many docs, googled, chatgpt, I barely have a working
configuration with only REGISTER working , but INVITE not working:

``` opensips.cfg
#
# 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.

Any idea why INVITE not working? :-)
