Introducing the VCS752

VCS752 Administrator and Provisioning Manual
Network Requirements
A simple VCS752 SIP Conference Phone with Bluetooth and DECT Accessories
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 VCS752 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 VCS752 conference phones so that IP addresses can be
auto-assigned. In most cases, your network router will have a DHCP server. By default, the
VCS752 has DHCP enabled for automatic IP address assignment.
If no DHCP server is present, you can assign a static IP to the VCS752. You can assign a
static IP address using the VCS752 menu. To assign a static IP, go to
Admin settings >
Network setting > 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 and/or enable automatic time
updates from an NTP server.
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 VCS752 firmware and/or
configuration settings manually.
Figure 1. VCS752 Installation Example
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.
