Introduction
This document covers how to implement the IPv4 & IPv6 dual stack mode on CME 8.0. This will help you if you have multiple partners connected across ipv6 & ipv4 network and you can Make, Receive calls to your network using any of the IP. This covers the configuration part on the CME to enable dual stack mode.

Note:- CME with dual-stack Mode and IPV6 preference. This "dual-stack mode" will enable CME to work on both ipv6&ipv4 and you can set any IP version as preference.
Note:- Both ipv4 & ipv6 source address configured for communication
