Text Conventions
Table 1 lists text formats and describes how they are used in this guide.
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 C620 SIP Wireless Conference Phone 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, along with C620-specific configurations
for optimal performance with those services. For the latest updates, visit our website at
www.snomamericas.com.
