1.2.3 Make Peer-to-peer Calls
Use the V300 to make a call to the recipient’s IP address without using a SIP server. Peer-to-
peer calls are also called “Point to Point” or “IP-to-IP” calls. You must know the peer’s IP
address in order to do this.
The following figure shows a basic example of how you would make a peer-to-peer VoIP call.
You make a call on your V300 (A), which sends your call through your modem or router (B)
and the Internet to the peer VoIP device (C).

1.3 Ways to Manage the V300
Use any of the following methods to manage the V300.
• Hardware keys. Use the control keys and LCD menus on the V300 for basic configuration.
• Web Configurator. This is recommended for everyday management of the V300 using a
(supported) web browser.
• FTP. Use File Transfer Protocol for firmware upgrades and configuration backup/restore.
• SPTGEN. SPTGEN is a text configuration file that you can edit and upload to the device.
This is especially convenient if you need to configure many devices of the same type.
1.4 Good Habits for Managing the V300
Do the following things regularly to make the V300 more secure and to manage the V300
more effectively.
• Change the web configurator password. Use a password that’s not easy to guess and that
consists of different types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Keep the V300 in a safe place. The LCD menus are not password-protected, so anyone
using the phone can access your phonebook, SIP account information, etc.
• Back up the configuration (and make sure you know how to restore it). Restoring an
earlier working configuration may be useful if the device becomes unstable or even
crashes. If you forget your password, you will have to reset the V300 to its factory default
settings to access the web configurator. If you backed up an earlier configuration file, you
would not have to totally re-configure the V300. You could simply restore your last
configuration.
