Mean-Opinion-Score (MOS)ITU-T P.800 Methods for Subjective Determination of Voice Quality
• Scores range from 1 to 5 • Excellent or “Toll” quality: MOS 4.0 or higher
PCM in the PSTN rates a MOS of 4.4
• Good: MOS 3.5 to 3.99• Fair: MOS 3.0 to 3.40• Poor: MOS less than 3.0• Bad: MOS of 1.0

> IP Telephony inherits IP Data Network threat models:Reconnaissance, DoS, Host Vulnerability Exploit, Surveillance, Hijacking, Identity Theft, Misuse, etc.
> QoS requirements of IP Telephony increase exposure to DoS attacks that affect: Delay, Jitter, Packet Loss, Bandwidth
> PC endpoints typically require user authentication, phones typically allow any user(exceptions: access/billing codes, Class of Service)
> User Identity Theft in traditional PBX phones carries over to IP Telephony… leads to:
Unauthorized Access and Privileges, Service Theft
> Device Identity Theft – malicious devices on the IP network acting like IP phones… leads to:
Reduced Service Availability, Eavesdropping,Inserting/Deleting/Modifying Audio Streams
Voice and Data Threat Models Merge

Its Only Getting Better
> Now is the time to invest in your people.> The technology behind Home agents is getting
better and easier to deploy.> Manufacturers are building products even your IT
department can manage.> The market place is driving a typical home agent
cost down below $1,000 (without the computer or chair).
