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.

Configuring Ipv4 & Ipv6 on CME 8.0

Configure the ipv6 & ipv4 dhcp pool for the IP Phones:

Configure both the ipv6 & ivp6 on the Interface configuration

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
