About the SBC SWe Lite Platform

The SBC SWe Lite is a virtualized, enterprise SBC designed for small- and mid-sized businesses. SWe Lite provides a virtual Customer Premise Equipment (vCPE) option for organizations looking to virtualize their interworking, security, and survivability for Unified Communications (UC). The SBC SWe Lite gives you the power to rapidly expand and activate features remotely using a simple license key, eliminating the need for on-site technicians or disruption to operations during peak business hours. With support for virtualization environments such as VMware ESXi, KVM, and Microsoft Azure, the SBC SWe Lite can be installed quickly and easily. 

Ribbon SBC SWe Lite Release 8.0.0 Build 180  is a new release for the SBC SWe Lite product line. 

New Features in this Release

CHOR-2372 / CHOR-2627 / CHOR-2639 Support SWe Lite in Microsoft Azure Marketplace

The Microsoft-certified SBC SWe Lite can now be deployed in Azure Marketplace, which saves enterprises time and energy on the SBC SWe Lite activation and configuration. In Azure, the SBC SWe Lite provides comprehensive security and interworking to enterprises deploying voice services in Microsoft Teams. Organizations can connect their SIP trunks to the Microsoft Phone System while optimizing Azure resources.

For more information, refer to:

• Running a SWe Lite via Microsoft Azure Marketplace
• Deploying an SBC SWe Lite via Azure Marketplace
• Virtual Machine Requirements - Microsoft Azure
• Adding vCPU and Increasing Memory/VM Size
• Powering Off and Deleting a SWe Lite Instance
• Best Practice - Running Microsoft Teams Direct Routing when SBC SWe Lite is Hosted in Azure

CHOR-1899/CHOR-2397 Call Session Capacity Increase 

 The call performance of the SBC SWe Lite has increased call session density, including RTP media manipulation mode sessions, at all supported VM resource configurations. Also, Microsoft Hyper-V now supports virtual machine resources for 2 vCPU (1.5 GB) and 4 vCPU (2.5 GB).

For performance numbers, refer to:

• SBC SWe Lite Performance and Capacity
• Adding vCPU and Increasing Memory/VM Size
• Hardware and Software Requirements - Microsoft Hyper-V
• Calculating Virtual Machine Requirements for an SBC SWe Lite

SYM-21781 Support Date-/Time-Based Call Routing

Time of Day Routing 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

CHOR-1185 Support Cloud-init for Interface Mapping and Initial Setup

The SBC SWe Lite supports the cloud-init function, which allows public clouds (such as Azure) to support automation. The cloud-init functionality allows the SBC SWe Lite to automatically deploy within an orchestrated environment.

For more information, refer to:

• Using Cloud-init to run the Initial Setup on SBC SWe Lite
  
• Running Initial setup on SBC SWe Lite
  
• Mapping Network Interfaces
  

CHOR-1717 RTP/RTCP Multiplexing Support

Enables Real-time Transport Protocol (RTP/RTCP Multiplexing) for combining the two protocols' packets (RTP for data traffic and RTCP for control information) onto a single multiplexed UDP port. RTP/RTCP Multiplexing is supported according to RFC 5761, in which the SDP contains the value of a=rtcp-mux. 

For more information, refer to:

• Configuring SBC Edge for Select Microsoft Teams Direct Routing Related Migration Scenarios

CHOR-1718 Opus Codec Transcode Support

The SBC SWe Lite now supports the Opus voice codec, which is used toward the IP side of a VoIP call. The codec improves audio quality, but comes with higher bandwidth consumptions.

For more information, refer to:

• Creating and Modifying Voice Codec Profiles
• Calculating Virtual Machine Requirements for an SBC SWe Lite
• SBC SWe Lite Performance and Capacity

CHOR-1761 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
• Managing Node-Level SIP Settings
• Configuring SBC Edge for Select Microsoft Teams Direct Routing Related Migration Scenarios
