Technical and management considerations for implementation of VoIP in a Dual-Stack (IPv4/IPv6) compatible environment

The Internet Protocol Version 4 (IPv4) has been the main communication protocol through which this technology has been deployed. Today, with the evolvement of Broadband technologies and the tendency to make all communication devices oriented IP, coupled with the problems raised by the limitation of IPv4 to address new requirements in term of availability of IP addresses, security and Quality Of Service (QoS) management, IP next-generation (IPng) also called IPv6 is the new version that definitely addresses these problems in the most effective way. However, the transition from the older to the newer version needs to be done with special considerations. Transition technics such as dual-stack are developed to handle this immediate need. This paper presents a proposal of technical and management parameters that organizations can consider to ensure successful implementation of VoIP telephony service in their network architecture where IPv4 and IPv6 are used as main communication protocols.
