Setting Up Messaging

Messaging is where all of your email accounts are located. You can send and receive email messages with an email account that you have with an Internet service provider (ISP), an email account that you access using a VPN (virtual private network) server connection (such as a work account), or any other IMAP (Internet Message Access Protocol) or POP3 (Post Office Protocol) email account. You enter the settings for your account in the Messaging application on your device.

Before You Begin
Before you can send and receive email messages, you need to set up your email account on your device. The Email Setup Wizard makes it easy and simple to set up your Outlook email and POP3/IMAP4 accounts on your device.

Work with your email provider or system administrator to gather the following information:

• Account type (POP3 or IMAP).
• Your user name and password.

1. It is the responsibility of employees with VPN privileges to ensure that unauthorized users are not allowed access to <Company Name> internal networks.
2. VPN use is to be controlled using either a one-time password authentication such as a token device or a public/private key system with a strong passphrase.
3. When actively connected to the corporate network, VPNs will force all traffic to and from the PC over the VPN tunnel: all other traffic will be dropped.
4. Dual (split) tunneling is NOT permitted; only one network connection is allowed.
5. VPN gateways will be set up and managed by <Company Name> network operational groups.
6. All computers connected to <Company Name> internal networks via VPN or any other technology must use the most up-to-date anti-virus software that is the corporate standard (provide URL to this software); this includes personal computers.

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.
