the SIP server’s IP address.
If you select Auto, you can’t edit the Transport
Protocol, Registrar Server, and Proxy Server
settings. If you select Specify, you can edit these
settings.
Transport Protocol Sets the protocol your system uses for SIP
signaling (your SIP network determines which
protocol is required).
▪ Auto: Enables automatic negotiation of
protocols in the following order: TLS, TCP, and
UDP. Polycom recommends this setting for
most environments.
▪ TLS: Provides secure SIP signaling. TLS is
available only when you register your system
with a SIP server that supports it. If you set this
option, your system ignores TCP/UDP port
5060.
▪ TCP: Provides reliable transport via TCP.
▪ UDP: Provides best-effort transport via UDP.
Force Connection Reuse Disabled by default (recommended).
When disabled, the system uses an ephemeral
source port for outgoing SIP messages. When
enabled, the system uses the active SIP listening
port as the source port (5060 or 5061, depending
on the negotiated SIP transport protocol in use).
You can use this setting to establish correct
operation with remote SIP peer devices, which
require that the source port match the contact port
in SIP messages.

Setting Description
BFCP Transport Preference Controls content sharing negotiation behavior.
When you use the Binary Floor Control Protocol
(BFCP), a relationship is established between the

Note: TCP is typically slightly slower but more
reliable than UDP. Some deployments don’t
support it, such as with session border controllers
(SBCs).
▪ Prefer UDP: (Default) Starts resource sharing
using UDP but falls back to TCP if needed.
▪ Prefer TCP: Starts resource sharing using TCP
but falls back to UDP if needed.
▪ UDP Only: Shares resources only using UDP. If
UDP is unavailable, your system can’t share
content in a separate video stream.
▪ TCP Only: Shares resources only through TCP.
If TCP is unavailable, your system can’t share
content in a separate video stream.

PKI Certificates
If your organization uses a public key infrastructure (PKI) for securing network connections, Polycom
recommends that you have a strong understanding of certificate management and how it applies to your
G7500 system.
PKI certificates authenticate secure network connections to and from the G7500 system. The system
uses standard PKI techniques to configure and manage certificates and certificate signing requests
(CSRs). ANSI X.509 standards regulate the certificate characteristics.
Your system can generate CSRs to send to a certificate authority (CA), a trusted entity that validates and
officially issues, or signs, PKI certificates. Your system uses those certificates for client and server
authentication.
If your system is in an environment without PKI, you don’t need a CA-signed certificate; the system
comes with a self-signed certificate for its TLS connections. When you deploy PKI, however, self-signed
certificates aren’t trusted and you must use CA-signed certificates.
Here are some examples of how you use PKI certificates:
▪ If your environment uses the 802.1X authentication framework for wired connections, create a CSR
and install the resulting CA-signed certificate on your system so it’s trusted on the network.
▪ If you want to navigate with a browser over a secure connection to your system web interface,
create a CSR and install the resulting CA certificate chain on your system to replace its factoryinstalled certificate, which is not trusted.

▪ Provisioning your system using RealPresence Resource Manager in a secure environment.
Note: Your system must have a Host Name in this situation.

Using a Provisioning Service on page 25
Create a Certificate Signing Request
If you deploy a PKI in your environment, create a CSR to make sure your G7500 system is trusted by its
network peers.
Note: Only a single CSR can exist at a time. After a CSR is generated, get it signed and installed
on your system before creating another. For example, if you generate a CSR and generate
another prior to having the first one signed and installed, the system discareds the previous
CSR.
Procedure
1. In the system web interface, go to Security > Certificates.
2. Select Create Certificate Signing Request (CSR).
3. In the Certificate Details form, complete the following fields:
CSR Information Description
Hash Algorithm Specifies the hash algorithm for the CSR: SHA-256 (recommended)
or SHA-1 (not recommended).
Common Name (CN) Specifies the system name. Polycom recommends the following
guidelines for this field:
▪ For systems registered in DNS, use the system's fully qualified
domain name (FQDN).
▪ For systems not registered in DNS, use the system's IP address.
Maximum characters: 64 (truncated if necessary). Default is blank.
Organizational Unit (OU) Specifies the business group defined by your organization. Default is
blank. Maximum characters: 64.
Note: The system supports only one OU field. If you want the CAsigned certificate to include more than one OU, download and
manually edit the CSR.
Organization (O) Specifies your organization's name. Default is blank. Maximum
characters: 64.
City or Locality (L) Specifies the city where your organization is located. Default is blank.
Maximum characters: 128.
State or Province (ST) Specifies the state or province where your organization is located.
Default is blank. Maximum characters: 128.
Country (C) Displays the country selected in the setup wizard. Cannot be changed

Open.
Your system accepts the following certificate file formats: .pem, .der, and PKCS #7 (which
typically has a .p7b filename extension).
The system checks the certificate data and, if the upload is successful, adds it to the page.
With your CA-signed certificate installed, your system is trusted by its network peers (provided that a root
certificate has established a chain of trust). This allows you to navigate with your browser over a secure
connection to the system web interface and perform administrative tasks.
View a Certificate
The G7500 system lists user-installed certificates in the system web interface, where you also can view
the contents of those certificates.
Procedure

communications are revoked by their issuing CAs.
Your system can check certificate revocation status with one of the following standard methods:
• Certificate Revocation List (CRL): File containing a list of certificates revoked by their issuing CA.
You must manually upload CRLs to your system.
• Online Certificate Status Protocol (OCSP): Your system contacts an OCSP responder, a web
server that provides revocation status through a query/response exchange.
Manually Upload a CRL
You can use CRLs to perform certificate revocation checks on your G7500 system.
Uploading a CRL fails unless you install all of the certificates in the issuing CA’s chain of trust for that
CRL.
This option is not available if your CRL is provisioned to the system.
Procedure
1. In the system web interface, go to Security > Certificates.
2. Configure the following settings:

Securing the System
Setting Description
Revocation Method To use the OCSP revocation method, select OCSP.
Allow Incomplete Revocation Checks When enabled, your system considers a revocation
check successful if there is no response or the
OCSP responder indicates a certificate’s status is
unknown.
Regardless of how you configure this setting, the
following statements apply:
• If the OCSP responder indicates a known
revoked status, your system treats it as a
revocation check failure and doesn’t allow the
connection.
• If the OCSP responder indicates a known good
status, your system treats it as a successful
revocation check and allows the connection.
Global Responder Address Specifies the URI of the OCSP responder (for
example, http://
responder.example.com/ocsp). The
responder is used when Use Responder
Specified in Certificate is disabled and sometimes
even when it’s enabled. Polycom recommends that
you always include a URI in this field regardless of
how you configure Use Responder Specified in
Certificate.
Use Responder Specified in Certificate Some certificates include the OCSP responder
address. When you enable this setting, your

Encryption
AES is standard on G7500 systems. When enabled, your system automatically encrypts calls with other
systems using AES.
A locked padlock icon displays on the connected monitor(s) when a call is encrypted. If a call is
unencrypted, you see an unlocked padlock. The padlock may not accurately indicate encryption status if
the call is cascaded or includes an audio-only endpoint. To avoid security ambiguity, participants can
verbally communicate the state of their padlock icon at the beginning of a call.
The following AES cryptographic algorithms ensure flexibility when negotiating secure media transport:
• H.323 (per H.235.6)
◦ AES-CBC-128 / DH-1024
◦ AES-CBC-256 / DH-2048
• SIP (per RFCs 3711, 4568, 6188)
◦ AES_CM_128_HMAC_SHA1_32
◦ AES_CM_128_HMAC_SHA1_80
◦ AES_CM_256_HMAC_SHA1_32
◦ AES_CM_256_HMAC_SHA1_80

H.460 Firewall/NAT Traversal
You can configure your G7500 system for firewall or network address translation (NAT) traversal using the
H.460.18 and H.460.19 standards. This includes environments with session border controllers (SBCs).
For example, an endpoint outside your network that’s initiating a SIP call connects to an SBC as a remote
endpoint. The incoming SIP traffic then traverses a firewall before connecting to the endpoint it’s calling
inside your network.
Real-time media streams often use UDP for their speeds. If your system is behind a firewall that restricts
access to UDP ports, however, you can configure your system for only TCP connections.
Caution: Systems deployed outside a firewall are potentially vulnerable to unauthorized access. Visit
the Polycom Security section of the Knowledge Base at Polycom Support for timely security
information. You can also register to receive periodic updates and advisories.
Configure the System for H.460 Firewall/NAT Traversal
You can configure your G7500 system for H.460 firewall/NAT traversal. Enable firewall traversal if you’re
using a cloud-based conferencing service or if your system is outside a corporate network (for example, a
home office).
Make sure you register your system with a network device that supports H.460.18 and H.460.19
standards (for example, a RealPresence Access Director system or a Polycom VBP device).
Procedure
1. In the system web interface, go to Network > Primary Network.
2. Go to Firewall.
Polycom, Inc. 56
Securing the System
3. Select Enable H.460 Firewall Traversal.
4. Verify the firewalls that you traverse allow your system to use outbound TCP and UDP
connections.
▪ Firewalls with a stricter rule set must allow the system to use at least the following outbound
TCP and UDP ports: 1720 (TCP), 14085-15084 (TCP), 1719 (UDP), and 16386-25386
(UDP).
▪ Firewalls must allow inbound traffic to the TCP and UDP ports used for outbound traffic.
5. Configure the following settings:
Setting Description
Fixed Ports Defines which TCP and UDP ports your system
uses for firewall traversal.
Enable this option if your firewall isn’t H.323
compatible. The system assigns a port range
starting with the TCP and UDP ports you specify
(port 3230 is where the range begins by default).
Note: For the fixed ports you configure, you must
open the corresponding ports on your firewall. For
H.323, open TCP port 1720. For SIP, open UDP
port 5060, TCP 5060, or TCP 5061 depending on if
you’re using UDP, TCP, or TLS, respectively, as the
SIP transport protocol.
Disable this option if your firewall is H.323
compatible or the system isn’t behind a firewall.
TCP Ports
UDP Ports
The starting value for the range of TCP and UDP
ports the system uses. The system automatically
configures the range based on the beginning value
you set here.
To allow H.323 traffic, you need two TCP and eight
UDP ports per connection. You must also open
TCP port 1720 on the firewall.
To allow SIP traffic, you need TCP port 5060 and
eight UDP ports per connection.
UDP port range: Because systems support ICE,
the range of fixed UDP ports is 32. The system
cycles through the available ports from call to call.
Fixed ports range and filters: You might notice
that the source port of a SIP signaling message is
not in the fixed ports range. When your firewall is
filtering on source ports, in the system web
interface, go to the SIP page and enable Force
Connection Reuse. When enabled, the system
uses port 5060 and 5061 for the source and
destination port (these must be open on the
firewall).

Web Proxies
A web proxy can help your G7500 system communicate outside your network securely and with
increased performance. For example, you can direct your system’s outbound requests through an
enterprise proxy.
You can configure your system to use a proxy one of the following ways:
▪ Automatic: You specify only the proxy credentials (if needed). Using DHCP, your system obtains a
URL to automatically download a proxy auto-configuration (PAC) file.
Polycom, Inc. 58
Securing the System
▪ Semi-automatic: You specify the proxy credentials and URL for automatically downloading a PAC
file.
▪ Manual: You specify the proxy address, port, and credentials. (This method lets you configure your
system with only one proxy.)
If your configuration includes automatically downloading a PAC file, there must be an expiration
associated with the file so the system knows when to download a new one. Make sure your PAC file
server includes an Expires header in its HTTP response (for example, Expires: Wed, 30 Oct
2016 09:30:00 GMT).
Your system can authenticate with a proxy using the following methods:
▪ Digest authentication (with either MD-5 or SHA-256 digest)
▪ NTLM authentication (only NTLMv2 is supported)
▪ Basic authentication (this insecure method is disabled by default)
▪ No authentication (or null authentication, meaning the proxy server doesn’t require credentials)
Your system supports the following services when configured to use a web proxy:
▪ Directory servers
▪ Provisioning service
▪ Calendaring service
▪ Software updates
