The following tables list the supported inbound and outbound ports.

About Full Duplex Echo Cancellation
Sometimes, RealPresence Desktop may not provide full duplex echo cancellation. To enable full duplex echo cancellation, your laptop needs to satisfy the following requirements:

• The audio clocks of microphone and speaker must synchronize.
• No caustic coupling exists between the microphone and speaker.
• No nonlinear process in the handling of the microphone and speaker data.

Unfortunately, many laptop microphones and speakers don’t meet the above requirements, which makes full duplex audio difficult. Additionally, USB microphones normally contain their own audio clock, making synchronization difficult.
To get the optimum audio experience, Poly recommends you to use the Poly room systems instead.
Resolved Issues
This release includes the following resolved issues.

Mac OS keeps changing your Microphone and Speaker device. It reduces the audio volume automatically to around 1/3 of the maximum volume.

Known Issues

The following table lists all known issues and suggested workarounds for RealPresence Desktop.
These release notes don’t provide a complete listing of all known issues that are included in the software. Issues not expected to significantly impact customers with standard voice or video conferencing environments may not be included.

Firewall and NAT Support

The Poly RealPresence Desktop provides firewall and Network Address Translator (NAT) traversal ability without the need to log in to a VPN. The following features are supported:

• Ability to keep Real-time Transport Protocol (RTP) NAT mapping alive during live streaming.

• Support for guest user dialing.

• Ability to support Secure Real-time Transport Protocol (SRTP) and Transport Layer Security (TLS) for the secure transmission of media.

• Ability to support Binary Floor Control Protocol (BFCP) over both TCP and UDP links (UDP preferred). Control signaling can now be forwarded using the best-effort traffic class in firewall and NAT traversal.

• Support for the following dial strings when you place calls without registering to a server.
  – H.323
  ◆ name@FQDN
  ◆ name@IP
  ◆ extension@FQDN
  ◆ extension@IP
  ◆ IP##extension
  – SIP
  ◆ @FQDN
  ◆ @

• Ability to verify server certificates by using installed root certificates (SIP, HTTPS, and LDAP) when establishing TLS connections.

• Ability to interoperate with Acme Session Border Controller (SBC) systems and Poly RealPresence Access Director.

• Support for SIP signaling FW/NAT traversal over TCP/TLS as defined in RFC5626.

• Ability to switch to a backup SIP server when the primary server fails.

Enterprise Scalable Video Coding (SVC) Mode
The Enterprise Scalable Video Coding (SVC) mode is an alternative to the AVC mode that has traditionally been supported. Differences between the two modes are listed in the following table.

Each participant in the conference call is received by the client as a separate video stream.| The composite video image is determined by the bridge based on administrator configuration.
A Caller ID is indicated by text in the appropriate window, which remains on display throughout the call.| Caller ID information is displayed intermittently.
Double-clicking or tapping on a participant’s video, content video, or local preview expands that video to full screen. Double-clicking or tapping again reverts the display to the composite image.| Layout may be controlled by dialing ** and then selecting a format.
Double-clicking or tapping on the remote video, content video, or local preview expands that video to full screen. Double-clicking or tapping again reverts the display to the composite image.

The SVC mode provides the following features:

• Video sends and receives up to 720p resolution.

• Frame rates of 7.5/15/30

• Support for AVC content

• Support for SVC auto layouts for video streams of up to nine far-end participants
  Last active speakers, resolution, bandwidth, and number of participants are adjusted based on network bandwidth and processor capabilities.
  When using SIP UDP in an SVC call and there’s more than 10 percent Packet Loss, the screen layout may display incorrectly. Changing to SIP TLS or TCP is recommended.

• Supported layouts of 1×1 and 1+1 through 1+10
  The maximum layout of 1+10 comprises nine remote participants plus one content sharing frame, and one local preview frame

• Support for SAC with at least two quality layers, for example, 48 Kbps and 10 Kbps

• Support for mixing up to three different audio streams from the MCU

• Support for combining up to nine different SVC video streams (call rate at 1920 Kbps) from the MCUs

SVC conference calls currently do not support the following:

• Far-end Camera Control (FECC)
• Recording with RealPresence Capture Server
• H.323 calls

In a poor network connection, sometimes a participant disconnects automatically from an SVC call.
This can result in a frozen video stream of the participant. The RealPresence Collaboration Server (RMX) system will clear the frozen stream in 30 minutes.

Access Media Statistics

Content Packets Loss Percentage| Total audio packet loss as a percentage of the total number of content packets transmitted by your system and those transmitted by the far end.

About AES Encryption
The following are requirements for using AES encryption in calls.
AES Encryption in H.323 Calls
To use AES encryption in H.323 calls, both you and the far end must satisfy the following requirements:

• Enable AES encryption.
  When working in the managed mode, the AES encryption of the RealPresence Desktop application is configurable through its provisioning server.
  When working in the standalone mode, the AES encryption of the RealPresence
  DesktopRealPresence Desktop application works as “When available” and isn’t guaranteed.

• Both you and your far end must support, or be compatible with, the same Key exchange and encryption method (H.235v3 w, or AES 128bit CBC).

AES Encryption in SIP Calls
To use AES encryption in SIP calls, both you and the far end must satisfy the following requirements:

• Enable AES encryption
• Enable TLS for SIP transport
• Support for SDES over TLS key exchange
• Support for AES 128-bit CBC mode over SRTP

When working in the managed mode, the AES encryption of the RealPresence Desktop application is configurable through its provisioning server.
When working in the standalone mode, the AES encryption of the RealPresence Desktop application works as “When available” and isn’t guaranteed.

Preparing Your Device for Mutual Transport Layer Security
You can establish secure communications using Mutual Transport Layer Security (MTLS) with provisioning servers such as Poly RealPresence DMA, CMA, or Poly Clariti Manager systems.
To establish MTLS connections, the client and server need to hold certificates issued from the same Certificate Authority (CA) and the root certificate of this CA.
Generate and Import Your Certificate
To import certificates, you must generate a Certificate Request (CSR) first by using a computer that has installed the OpenSSL tool.
To generate and import your certificate:

1. Open the Terminal window from your Mac. (Applications > Utilities > Terminal.app)

2. Go to the Documents folder and generate the private key client.key. For example:
   localhost$ cd documents
   localhost$ openssl genrsa -out client.key 1024

3. Generate the certificate request client.csr. For example:
   localhost$ openssl req -new -key client.key -out client.csr
   The requested information is incorporated into your certificate request. Enter a distinguished name (DN) and other information into the following fields (you can leave some blank).
   —Country Name (2 letter code) [GB]:cn —CSR info.
   State or Province Name (full name) [Berkshire]:bj —CSR info.
   Locality Name (eg, city) [Newbury]:bj —CSR info.
   Organization Name (eg, company) [My Company Ltd]:plcm —CSR info.
   Organizational Unit Name (eg, section) []:caqa —CSR info.
   Common Name (eg, your name or your server’s hostname) []:caqa —CSR info.
   Email Address []:[email protected] —CSR info.
   Enter the following “extra” attributes to be sent with your certificate request.
   Write down the challenge password. You will need it later in the procedure.
   A challenge password []:1234 —–see the note below.
   An optional company name []:poly

4. Submit the certificate request to your CA:
   a View the content of the file client.csr using the following command:
   localhost > more client.csr
   Select and copy its content from BEGIN CERTIFICATE REQUEST to END CERTIFICATE
   REQUEST.
   b Go to your CA’s web interface http://<CA’sIPaddress>/certsrv/, and select Request a certificate.
   c Choose Advanced certificate request.
   d Select Submit a certificate request by using a base-64-encoded CMC or PKCS #10 file, or Submit a renewal request by using a base-64-encoded PKCS #7 file.
   e Paste the content of the file client.csr in the Saved Request text field, and select Submit.
   f Choose Base 64 encoded and then select Download certificate.
   The file is saved as certnew.cer by default in the folder Downloads.

5. Move the generated certnew.cer file to the Documents folder.

6. Convert the file ccertnew.cer to a .p12 file by using the openSSL tool. Note that the export password
   should be the same as the challenge password you set in Step 4. For example:
   localhost$ openssl pkcs12 -export -in certnew.cer -inked client.key –out
   client.p12 -name testp12
   Enter Export Password:
   Verifying – Enter Export Password:

7. Encrypt the challenge password you set:
   a Go to Convert String.
   b Enter the challenge password in the text field, and select Base64 Encode!.
   c Copy the encoded text from the following text field, and save it as a .pwd file. For example: client.pwd.

8. Open the Documents/Polycom RealPresence Desktop folder, and then copy the files client.p12 and client.pwd to the folder.

To import the root certificate of your CA:

1. Go to your CA’s web address http://<CA’s IP address>/certsrv/, select Download a CA certificate, certificate chain, or CRL.
2. Select Base 64, and select Download CA Certificate.
3. Double-click the CA file, and select Always Trust. If you see the Add Certificates message, select Add before you select Always Trust.
