For more information, refer to:

• Creating and Modifying SIP Signaling Groups
• Configuring SBC Edge for Select Microsoft Teams Direct Routing Related Migration Scenarios

SYM-20110 RASO - ASM Update Progress

Microsoft's Cumulative Updates include bug fixes and new features for the Skype for Business Server server (such as the SBA). Once Microsoft releases these updates, Ribbon validates them and creates an ASM_CU package (which includes the ASM Roll-up file), which is available via Ribbon Support Portal for installation. This new feature tracks the progress of the ASM Roll-up installation; the new progress bar signals that the upload is running in the background.

For more information, refer to:

• ASM Roll-up Update
• Installing an ASM Package

SYM-20206 Offer TLS 1.2-Only Option on ASM SBA

Enables more security by supporting a TLS 1.2-Only configuration option (for supporting TLS 1.2 as described in RFC 5246), in addition to the TLS 1.0-1.2 configuration option.

For more information, refer to:

• Managing TLS Profiles
• Creating and Modifying TLS Profiles
• Applying an SBA Security Template

SYM-21781 Support Date/Time Based Call Routing

Time of Day enables the SBC to select a route for a call based on the local time and date; this option allows each specific route to optionally be selected based on the current local system time. The Time of Day tables define a group of Time of Day entries which specify times and days of the week.

For more information, refer to:

• Working with Time of Day
• Managing Time of Day Tables
• Creating and Modifying Entries to Time of Day Tables
• Best Practice - Configuring Time of Day Routing

SYM-22809 Ribbon SBC Edge with Polycom VVX Local Survivability

Polycom introduced on 5.8 firmware a feature called PSTN Failover. This feature allows creation of a Local Survivability configuration for Skype for Business users if Skype servers (for either Office 365 or On Premises) are unavailable. When Local Survivability is configured for Polycom VVX phones, phones can fall back to an appropriately configured SBC Edge if connectivity to Skype is lost. Refer to the following Best Practice for details:

• Best Practice - Configure SBC Edge with Polycom VVX Local Survivability

SYM-22880 Add CCE - Teams Ports and DNS Validation on SBC

Release 8.0 includes a set of tools that test port readiness for the services required for CCE or Microsoft Teams Direct Routing. Connectivity Check tools enable Ribbon Support to work with deployment teams to prevent service issues due to firewall configuration and other issues.

For more information, refer to Working with Connectivity Check -- Verifying Service and Port Requirements for CCE and Teams.

SYM-24006 Failover SIP Registration

The Failover SIP Registration feature allows the SBC to handle registration to, and subsequent call processing to a secondary SIP server if the primary SIP server fails – for example, if the primary server, becomes unreachable, has registration expiration with re-registration failure, or refuses to accept registrations/calls for some other reason. Failover SIP registration is completed according to the Priority order of the SIP Servers. For more information, refer to:

• Creating and Modifying SIP Signaling Groups
• Creating and Modifying SIP Profiles
• Managing SIP Server Tables
• Creating and Modifying Entries in SIP Server Tables

SYM-24420 Export Transformation Table - Allow User to Select which Tables to Export

During transformation table export, the WebUI displays a list of all transformation tables as you select one or more tables to export as XML-formatted files. For more information, refer to Importing and Exporting Transformation Tables.

SYM-24421 Add the Ability to Repeat/Restart an Already-Run Packet Capture Setup

After a packet capture is performed on an SBC 1000/2000, the WebUI includes an option for restarting or repeating the last packet capture performed. For more information, refer to Working with Packet Capture and Packet Capture - Best Practice.

SYM-24195 Easy Configuration Wizard for Microsoft Teams Direct Routing

The Easy Configuration Wizard for Microsoft Teams Direct Routing adds Easy Configuration templates for the following Provider-to-User configuration scenarios:

• IP PBX ↔ Microsoft Teams
• SIP Trunk ↔ Microsoft Teams
• ISDN PSTN ↔ Microsoft Teams

The IP PBX template that previously addressed user-side configuration only now provides easy configuration for both the User and Provider sides. In addition, the Microsoft UC scenario has been renamed to "Microsoft On Premises." For more information, refer to:

• Configure an IP PBX with Microsoft Teams
• Configure SIP Trunk with Microsoft Teams
• Configure ISDN PSTN with Microsoft Teams

SYM-24472 ICE Lite Agent Support

With the addition of the ICE (Interactive Connection Establishment) Lite Agent Support feature, the SBC 1000/2000 now supports both full and lite implementations of ICE as described in RFC 8445.  ICE lite, for public Internet ICE agents, interfaces to the Microsoft TEAMS Direct Routing interface. The SBC 1000/2000 integrates Microsoft Teams clients by acting as an ICE lite agent endpoint for SIP calls involving Network Address Translators (NATs). This feature enables direct routing between an existing enterprise voice infrastructure (that is, the PSTN carrier and SIP trunks used for trunking services) and the Microsoft Phone System in Office 365. The SBC acts as a PSTN gateway; sessions for Microsoft Teams users can be routed directly to the PSTN through the SBC.

For more information, refer to:

• Working with the SBC Edge as an ICE Lite Agent
