Release Notes

UC Software Version 5.9.5

Dual-Tone Multi-Frequency Tones Parameter
Poly UC Software 5.9.5 introduces a new parameter for Dual-Tone Multi-Frequency (DTMF) to publish the DTMF frequency on the Opus codec. tone.dtmf.rfc2833.SupportOpusClockRate
1 � (default) Publishes the Telephone-event DTMF frequency as 48000 Hz along with 8000 Hz on Opus codec. 0 - Publishes the Telephone-event DTMF frequency as 8000 Hz on Opus codec.
Session Traversal Utilities for NAT (STUN) Parameters
Poly UC Software 5.9.5 supports Session Traversal Utilities for NAT (STUN), a network protocol used in NAT traversal for real-time IP communications, such as voice, video, and messaging. This section lists parameters that configure Simple Traversal of UDP though NAT (STUN). nat.refresh.interval
Set the time interval for the phone to send STUN binding indications to keep the NAT port open and the phone reachable. 30 seconds (default) - The phone sends STUN binding indications for every 30 seconds to keep the NAT port open and the phone reachable. 0 second - Disable STUN Binding indication to refresh NAT bindings. 3600 seconds nat.device.pollInterval Set the time interval for the phone to send STUN binding request to the STUN server to detect whether NAT device is rebooted. 60 seconds (default) - The phone sends the STUN binding requests to the STUN server for every 60 seconds. If NAT IP address or the port details in the STUN binding response don't match with the previous binding response, the phone automatically restarts. 0 - The phone doesn't check whether NAT device is rebooted. If NAT device is rebooted and the NAT IP address or the port is changed, the phone doesn't receive any incoming messages as the IP address and port details published in SIP register message don't match. You need to restart the phone manually to make the changes effective. Poly recommends not to set the value as 0 second. 900 seconds
FIPS 140-2 Compliance Support
The Federal Information Processing Standard (FIPS 140-2) compliance is a cryptographic function. This feature is now supported on VVX 501 and 601 business media phones. The following parameter enables or disables the FIPS 140-2 feature. device.sec.TLS.FIPS.enabled 0 (default) - Does not allow the phone to use the FIPS-compliant cryptography feature. 1 - Allows the phone to use the FIPS-compliant cryptography feature.

Download the Distribution Files
To download UC Software 5.9.5, you can choose the combined UC Software package or the split UC Software package, both in ZIP file format. The combined version contains all files for all phone models. The split software package is smaller, downloads more quickly, and contains sip.ld files for each phone model. This enables you to choose provisioning software for your phone model and maintain software versions for each model in the same root directory.
For general use, Polycom recommends using the split resource file that corresponds to the phone models for your deployment. To match the correct UC software resource file to your phone model, see the table Error! Reference source not found. table. If you're provisioning your phones centrally using configuration files, download the corresponding resource file and extract the configuration files to the provisioning server. Make sure that you maintain the folder hierarchy in the ZIP file.
The current build ID for the sip.ld and resource files is UCS 5.9.5.0614 rts10.

Constraints and Limitations
This section identifies known constraints and limitations of this release as it interoperates with other platforms or devices.
Successful Connection in an SRTP Environment
For endpoints to successfully connect in a Securte Real-time Transport Protocol (SRTP)-enabled environment, endpoint must be able to negotiate an SRTP offer. That means, endpoints must have at a minimum Offer SRTP set to Yes. If the endpoints are not so configured, blind transfers will fail.
Some Call Flow Failures with Avaya Aura 7.1
After upgrading to Avaya Aura 7.1, failures in some call flows occur when connected SIP devices change URIs with "sips:" indicators to "sip:" on an intermediate route and via headers, which is not allowed as per SIP RFC 3261.
Headset Volume Change and VVX Phone Display not in Synch
The volume up and down settings on some headsets (Blackwire 5200 series and Encore Pro HW500 series) are not always synchronize with the VVX phones LCD display.
Poly VVX Phone Status Always Green
When in an Avaya Aura Session Manage 5300 environment, Poly VVX phones registered as buddy to an Avaya 1140 endpoint always show green status when the Avaya 1140 endpoint is in a call.

UC Software Version 5.9.5

� Sign In Remotely Using Web Sign-In for Skype for Business
Third-Party Application ID Implementation on Skype for Business Phones
Microsoft announced the end of support for the existing Azure application ID currently used by third-party device vendors that use the OAuth 2.0 authorization protocol. To retain authentication to Microsoft services and the ability to sign in to Skype for Business, you must update the firmware to implement a third-party application ID on all impacted certified Skype for Business phones by January 15, 2020. The following deployments include Skype for Business IP phones certified under Microsoft's 3rd Party IP Phones (3PIP):
Skype for Business Online Skype for Business On-Premises Hybrid (with modern authentication deployed) Polycom adheres to the Microsoft announcement and has implemented the third-party application ID. To implement the third-party application on Skype for Business phones: 1 Go to the consent URL and sign in with tenant administrator credentials. 2 Click Accept to grant permission to allow the Poly ID application to access the required resource's
permissions. Note: You must go to the consent URL and accept permission before you upgrade to the new firmware. 3 Upgrade the impacted phones to the new firmware version.
System Constraints and Limitations
This section provides information on contraints and limitations when installing UCS 5.9.4 in your environment.
� Authentication of Microsoft Exchange 2013 Services � Downgrade Behavior from Polycom UC Software 5.9.4
Authentication of Microsoft Exchange 2013 Services
Polycom UC Software 5.9.4 contains embedded Poly application ID code, which can cause the authentication for Exchange services with Hybrid Modern Authentication (HMA) enabled to fail with OAuth 2.0 on VVX phones.
Downgrade Behavior from Polycom UC Software 5.9.4
Downgrading from UC Software 5.9.4 to any earlier UC Software version may result in sign-in failure. To continue using Skype for Business on VVX phone successfully, re-sign in to Skype for Business.

VVX phones fail to join a conference when the meeting subject contains special characters.
When you connect a VVX phone to the HELD server, the phone must respond with a valid certificate after receiving the request message from the server.
When a local conference is initiated on a Shared Call Appearance (SCA) phone, a remote SCA phone shows missed calls.
When dialing to an anonymous user from a call list, the phone sends the acknowledgement with spaces in the SIP request-URI, causing network congestion.
After a blind transfer, calls from a VVX D60 handset fail and users can't resume the call.

PLANTRONICS + POLYCOM

NOW TOGETHER AS POLY.

Release Notes

UC Software Version 5.9.5

DHCP IP Address Cache
Polycom UC Software supports the Dynamic Host Configuration Protocol (DHCP) IP address cache to retain IP addresses on VVX phones. When you enable the IP address caching feature, there aren't any service interruptions even if the IP address lease time expires and the DHCP server doesn't respond.

TLS Support for BToE
Polycom BToE application supports the Transport Layer Security (TLS) protocol to authenticate VVX phones with the following features:
Polycom UC Software uses TLS protocol v1.2 to authenticate VVX phones using BToE application v4.0.0.
The TLS protocol takes precedence over the SSH protocol. If TLS connection fails between the VVX phone and the Polycom BToE Connector application, then
the connection falls back to SSH.

Polycom Cloud Connector
Polycom UC Software introduces the Polycom Cloud Connector to send device analytics to Polycom Cloud Services. You must enable the device.da.enabled parameter to send device analytics to Polycom Cloud Services.

Enhancement to Wi-Fi Settings
Polycom VVX phones now display Wi-Fi settings only when you connect a Wi-Fi dongle. Wi-Fi dongle doesn't support on Expansion modules USB port.
