OpenSIP3.4 路由脚本之我见

熟悉我的都知道，我早就习惯了 Kamailio

用 osipsconfig 产生 Residential 的路由脚本，仔细看了下，还是不太习惯

首先，有二处认证，感觉很怪异

其次，没有宏定义，要用 m4 等工具来进行处理

再次，版本变化太大，脚本的兼容性比较差

您对此有什么看法？

# OpenSIPS residential configuration script
#     by OpenSIPS Solutions <[e-mail]>
#
# 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:
