Cisco updates their exam tracks every few years and requires each certified person to re-certify every few years (typically 3). Recently they have introduced a new track for those wishing to pursue the VoIP side of things.
CCNA Voice Certification can be found here and outlines what you will need for this exam. The exam is a good addition to their already strong line of certifications and will increase their precense in the VoIP market.
