Audience
This guide is written for installers and system administrators. It assumes that you are
familiar with networks and VoIP, both in theory and in practice. This guide also assumes
that you have ordered your IP PBX equipment or service and selected which PBX features
you want to implement. This guide references specific IP PBX equipment or services only
for features or settings that have been designed for a specific service. Please consult your
equipment supplier or service provider for recommended switches, routers, and firewall
and NAT traversal settings, and so on.
As the C520 Conference becomes certified for IP PBX equipment or services, Snom may
publish interop guides for those specific services. The interop guides will recommend
second-party devices and settings, alongwithC520-specificconfigurationsforoptimal
performancewiththoseservices.For the latest updates, visit our Wiki at

About the C520 conference phone
The C520 WiMi Conference Phone is a conference phone designed to work with popular
SIP telephone (IP PBX) equipment and services. Once you have ordered and configured
your SIP equipment or service, the C520 enables you to make and receive calls as you
would with any other business phone. In addition to its speakerphone and conferencing
features, the C520 provides calling features like hold, transfer and speed-dial numbers.
The C520 conference phone features include:
 2.5-inch backlit Liquid Crystal Display
 Bluetooth and DECT connectivity for cell phones and headsets
 Up to 3 SIP account registrations
 Up to 6 active SIP sessions
 3-way conferencing
 200-entry Call Log
You can configure the C520 using the menus on the phone, a browser-based interface
called the WebUI, or an automatic provisioning process (see “Provisioning Using
Configuration Files” on page 85). The WebUI enables you to configure the C520 using a
computer that is connected to the same Local Area Network. The WebUI resides on the
device and may get updated with firmware updates.
