Basic Firewall/NAT Traversal Connectivity
Basic Firewall/NAT Traversal Connectivity allows RealPresence Group systems to connect to the
SIP-based RealPresence solutions using the Acme Packet Net-Net family of Session Border Controllers
(SBC). A RealPresence Group system connects to the Acme Packet Net-Net SBC as a remote enterprise
endpoint. The remote enterprise endpoint is registered to the enterprise’s SIP infrastructure and connects
to an internal enterprise endpoint through the enterprise firewall.
For details about the use and configuration of the Acme Packet Net-Net SBC used in conjunction with this
feature, refer to Deploying Polycom Unified Communications in an Acme Packet Net-Net Enterprise
Session Director Environment.
RealPresence Group systems now also provide full mutual TLS support for SIP and XMPP Presence
connections. Full mutual TLS support gives administrators the ability to identify and authenticate devices
attempting to join conferences from outside the enterprise network.
Set SVC Call Preferences
Scalable Video Coding (SVC) conferencing provides several benefits, including fewer video resource
requirements, better error resiliency, lower latency, and more flexibility with display layouts.
You can make and receive SVC multipoint calls when the Polycom RealPresence Group system is
connected to an SVC-compatible bridge through the RealPresence Distributed Media Application (DMA). In
an SVC-based conference, each SVC-enabled endpoint transmits multiple bit streams, called simulcasting,
to the Polycom RealPresence Collaboration Server (RMX). The RealPresence Collaboration Server sends
or relays selected video streams to the endpoints without sending the entire video layout. The streams are
assembled into a layout by the SVC-enabled endpoints according to each of their different display
capabilities and layout configurations.
To make SVC point-to-point calls, the RealPresence Group system must be registered to a Lync 2013 or
Skype for Business 2015 server. In a Microsoft Lync 2013 or Skype for Business 2015 hosted multipoint or
point-to-point call, you can view multiple far-end sites in layouts. RealPresence Group 500 and 700 systems
display up to five far-end sites on Lync 2013 or Skype for Business 2015 hosted (SVC), multipoint calls.
For more information on the features, limitations, and layouts of SVC-based conferencing, refer to the
Polycom RealPresence SVC-Based Conferencing Solutions Deployment Guide available at

Enable SVC Dialing Options
Dialing preferences help you manage the network bandwidth used for calls and establish an SVC call
configuration. You can specify the default and optional call settings for outgoing calls. You can also limit the
call speeds of incoming calls.
To configure dialing options:
1
In the web interface, go to Admin Settings > Network > Dialing Preference > Dialing Options.
2
Configure these settings.
