snom 821 User Manual Setting up the Phone

Initializing and registering the phone

Prerequisites

To be able to use VoIP, you or your company must have:

• A broadband internet connection.

• Access to the internet via a router. This could be a separate device available in various versions

from many different manufacturers or in the form of a router on a server or a PC.

• Account information provided by your network administrator or a VoiP account with a VoIP service

provider who supports the VoIP SIP standard. You can use up to 12 VoIP accounts with one or

more VoIP providers.

You will need the registration information received from your Internet service provider or your network

administrator. Required and optional data differ from provider to provider. They normally include:

• Account (usually the phone number). On snom phones, an account is called an "identity".

• Registrar

• Password

User name, authentication name, outbound proxy may also be required. These are settings that can

only be conﬁgured on the web interface of the phone after it has been successfully registered. If

your provider or your network provides a mailbox account, that setting is also conﬁgured on the web

interface. For more information, see "Identities/accounts" on page 66.

Initialization

snom phones are plug-and-play. Once the phone is connected to your network, it will begin to initialize.

Note: Normally the initialization is completely automatic, using DHCP. If the phone

cannot discover a DHCP server in the subnet, you will be asked: Are you using DHCP?

If your network does not support DHCP, press

and enter the IP address, netmask, IP

gateway, and DNS server manually. Ask your Internet service provider or your network

administrator for them.
