Network Requirements - Snom C620 Administrator And Provisioning Manual

Network Requirements

A simple C620 SIP Wireless Conference Phone installation example is shown in Figure 1.
A switched network topology is recommended for your LAN (using standard 10/100
Ethernet switches that carry traffic at a nominal rate of 100 Mbit/s).
The office LAN infrastructure should use Cat.-5/Cat.-5e cable.
The C620 base station requires a wired connection to the LAN. However, wireless
connections from your LAN to other devices (such as laptops) in your office will not impede
performance.
A Dynamic Host Configuration Protocol (DHCP) server is recommended and must be on
the same subnet as the C620 SIP Wireless Conference Phones so that IP addresses can
be auto-assigned. In most cases, your network router will have a DHCP server. By default,
the C620 has DHCP enabled for automatic IP address assignment.
If no DHCP server is present, you can assign a static IP to the C620. You can assign a static
IP address using the C620 menu.
To assign a static IP: On the handset Main menu, go to Status & Settings > Admin
settings > Network setting > IPv4 (or IPv6) > Set static IP.
If you do not have a DHCP server or do not manually assign static IPs, you will not be able
to access the WebUI.
A DNS server is recommended to resolve the path to the Internet and to a server for
firmware and configuration updates. If necessary, the system administrator can also
download upgrade files and use the WebUI to update the C620 firmware and/or
configuration settings manually.
Introducing the C620
Some DHCP servers have default settings that limit the number of network IP
addresses assigned to devices on the network. You should log in to your server
to confirm that the IP range is sufficient.
