VPN Setup

• iPhone integrates with most existing VPN networks, so minimal configuration should be necessary to enable iPhone access to your network. The best way to prepare for deployment is to check if iPhone supports your company’s existing VPN protocols and authentication methods.
• It’s a good idea to review the authentication path to your authentication server to make sure standards supported by iPhone are enabled within your implementation.
• If you plan to use certificate-based authentication, ensure you have your public key infrastructure configured to support device- and user-based certificates with the corresponding key distribution process. For additional documentation regarding digital certificates for IPSec VPNs, visit: https://cisco.hosted.jivesoftware.com/docs/DOC-3592.
• If you want to configure URL-specific proxy settings, place a PAC file on a web server that is accessible with the basic VPN settings and ensure that it is hosted with the application/x-ns-proxy-autoconfig MIME type.
  Check with your solution providers to confirm that your software and equipment are up to date with the latest security patches and firmware.

Introduction to Service Processor Interfaces
The service processor (MP or GSP) utility hardware is an independent support system for nPartition servers. It provides a way for you to connect to a server complex and perform administration or monitoring tasks for the server hardware and its nPartitions.

The main features of the service processor include:

• Command Menu
• nPartition Consoles
• Console Logs
• Chassis Code Viewer (on HP 9000 servers with HP PA-8700 processors) or Event Log Viewer (on servers based on the HP sx1000 chipset)
• Virtual Front Panels (live displays of nPartition and cell states)

These features are described in more detail in Service Processor (MP or GSP) Features on page 18.

Part One: An Introduction to VoIP
Summary: What Is Voice Over Internet Protocol?
Voice over internet protocol (VoIP) is a communications technology that uses the internet to transfer voice signals in the form of bits and bytes. It delivers these bits and bytes to a specified internet address rather than a telephone number. It’s easier to think of it as being like sending e-mail from one computer to another, but in real time and using voice instead of text. The technology that most likely runs your existing switchboard and phones is a traditional public switched telephone network (PSTN) service. VoIP’s advantage over this is its ability to combine several services, such as voice mail, video, e-mail and conferencing. This instantly increases your ability to collaborate and can result in higher productivity.
