Seamless Integration with UCaaS: SBC SWe for Microsoft Teams and Zoom Phone

In the face of rapidly growing popularity of Unified Communications as a Service (UCaaS), enterprises are increasingly faced with the need to integrate various platforms. SBC SWe, as a key element of the infrastructure, provides secure and reliable communication between your network and Microsoft Teams or Zoom Phone. This article provides a technical guide to setup and integration, geared towards large enterprise customers and telecom operators.

SBC SWe: A Key Component of UCaaS Integration

SBC SWe is a software Session Border Controller (SBC) solution designed to provide security, compatibility, and quality of service in VoIP networks. It plays a central role in integrating with Microsoft Teams and Zoom Phone, acting as an intermediary between your corporate network and cloud UCaaS platforms.

Benefits of Using SBC SWe for UCaaS Integration

  • Security: Protects the network from threats such as DoS attacks, SIP attacks, and traffic interception.
  • Compatibility: Ensures interoperability between different network elements and protocols.
  • Quality Control: Monitors and optimizes call quality (QoS) to ensure the best user experience.
  • Routing and Traffic Management: Intelligent call routing to optimize resource utilization and reduce costs.
  • Protocol Normalization: Conversion and adaptation of various VoIP protocols to ensure compatibility.

Setting up Direct Routing for Microsoft Teams with SBC SWe

Direct Routing is a method of connecting an enterprise’s telephone infrastructure to Microsoft Teams, allowing Teams to be used to make and receive external calls. SBC SWe plays an important role in this process, providing a secure and reliable connection between your network and Teams.

Prerequisites

  1. Active Microsoft Teams subscription.
  2. Assigned Phone System licenses for Teams users.
  3. Domain name registered in Microsoft 365.
  4. Deployed and configured SBC SWe with a public IP address.
  5. Configured SIP trunk for connection to SBC SWe.

SBC SWe Configuration for Direct Routing

1. Certificate Configuration

To ensure secure communication, a valid SSL certificate must be installed on SBC SWe. The certificate must be issued by a trusted Certification Authority (CA). Make sure the certificate includes the domain name of the SBC SWe.

2. Creating a SIP Profile

The SIP profile defines the SIP trunk parameters for connecting to Microsoft Teams. You must specify the following parameters:

  • Transport Protocol: TLS (for secure communication).
  • SIP Port: 5061 (standard port for TLS).
  • SBC FQDN: The fully qualified domain name of your SBC SWe.
  • SRTP Support: Enabled (for media traffic encryption).

3. Configuring Routing Rules

Routing rules define how calls are routed between your network and Microsoft Teams. You need to configure rules for inbound and outbound calls.

Rules for Outbound Calls (from Teams to PSTN):
  • Specify a number pattern that matches your numbering scheme.
  • Specify the SIP profile created in step 2.
  • Define the codec used for media traffic transmission (G.711, G.729).
Rules for Inbound Calls (from PSTN to Teams):
  • Specify the DID range (Direct Inward Dialing) for your organization.
  • Specify the SIP profile created in step 2.
  • Configure call routing to specific Teams users.

4. Microsoft Teams PowerShell Configuration

To complete the Direct Routing setup, you need to use PowerShell. Follow these steps:

  1. Connect to Microsoft Teams PowerShell.
  2. Create an SBC.
  3. Enable Media Bypass (recommended for optimizing call quality).
  4. Configure voice routing settings.
  5. Assign a voice routing policy to Teams users.
Example PowerShell commands:
# Connect to Teams PowerShell
 Connect-MicrosoftTeams # Creating an SBC
 New-CsOnlinePSTNGateway -Identity "sbc.example.com" -Fqdn "sbc.example.com" -SipSignalingPort 5061 -MaxConcurrentSessions 100 -EnableSrtp $true -MediaBypass $true # Configure voice routing
 New-CsOnlineVoiceRoute -Identity "RouteToSBC" -GatewayList "sbc.example.com" -NumberPattern "^+1.*" -Priority 1 New-CsOnlineVoiceRoutingPolicy -Identity "VPRoutingPolicy" -OnlinePstnUsages "USAPSTN" Grant-CsOnlineVoiceRoutingPolicy -Identity "user@example.com" -PolicyName "VPRoutingPolicy"

SBC SWe: Integration with Microsoft Teams and Zoom Phone - Technical Guide

Integration with Zoom Phone using SBC SWe

Similar to Microsoft Teams, SBC SWe can be used to integrate with Zoom Phone, providing a secure and reliable connection between your network and the Zoom cloud platform.

Prerequisites

  1. Active Zoom Phone subscription.
  2. Assigned Zoom Phone licenses for users.
  3. Deployed and configured SBC SWe with a public IP address.
  4. Configured SIP trunk for connection to SBC SWe.

SBC SWe Configuration for Zoom Phone

1. Configure a SIP Trunk in Zoom Phone

In the Zoom Phone management panel, you need to configure a SIP trunk, specifying the following parameters:

  • Trunk Name: The name identifying the trunk.
  • SBC FQDN: The fully qualified domain name of your SBC SWe.
  • Transport Protocol: TLS (for secure communication).
  • SIP Port: 5061 (standard port for TLS).
  • Authentication: Authentication based on IP address or SIP credentials may be required.

2. Configuring a SIP Profile on SBC SWe

On SBC SWe, you need to create a SIP profile that matches the SIP trunk settings in Zoom Phone. Specify the following parameters:

  • Transport Protocol: TLS.
  • SIP Port: 5061.
  • Zoom Phone FQDN: Zoom Phone server FQDN (provided by Zoom).
  • Authentication: Configure authentication according to Zoom Phone requirements.

3. Configuring Routing Rules

Configure routing rules on SBC SWe to route calls between your network and Zoom Phone.

Rules for Outbound Calls (from Zoom Phone to PSTN):
  • Specify a number pattern that matches your numbering scheme.
  • Specify the SIP profile created in step 2.
Rules for Inbound Calls (from PSTN to Zoom Phone):
  • Specify the DID range (Direct Inward Dialing) for your organization.
  • Specify the SIP profile created in step 2.
  • Configure call routing to specific Zoom Phone users.

Security and VoIP Protocols

SBC SWe supports various security protocols, providing protection against threats and call confidentiality.

  • TLS (Transport Layer Security): Encryption of SIP signaling traffic to protect against interception and spoofing.
