Connecting Microsoft Teams to Etisalat & du PBX Systems: The Ultimate AudioCodes SBC Gateway Guide for UAE Businesses

Modern organizations across Dubai and the wider UAE are rapidly consolidating their communications into Microsoft Teams. However, companies operating in the region face a unique challenge: Microsoft Calling Plans are not natively available in the UAE.

To enable external calling (PSTN) directly inside Microsoft Teams using your existing landline or office numbers, you must use Microsoft Teams Direct Routing.

This is where a Session Border Controller (SBC) comes in. By deploying an AudioCodes SBC Gateway in Dubai, UAE, you can bridge Microsoft Teams with your local PBX system and keep your telecom contracts with Etisalat or du.

How the AudioCodes SBC Gateway Connects Microsoft Teams to Local UAE Carriers

An AudioCodes SBC acts as a secure, intelligent translator. It sits between the Microsoft cloud, your internal corporate network, your legacy PBX system, and the local PSTN networks provided by Etisalat or du.

When a team member places an outbound call using Microsoft Teams:

1. The Teams client sends the call over the internet to the Microsoft 365 cloud.
2. Microsoft routes the call to the AudioCodes SBC Gateway.
3. The SBC securely translates the voice packets and forwards them to either your on-premises PBX or directly to your Etisalat/du SIP trunk.
4. The call reaches its external destination seamlessly using your office's local landline number.

Key Benefits of Using AudioCodes SBC for Direct Routing in Dubai

• Retain Your Local Landline Numbers: No need to change your company phone numbers. You can map your existing Etisalat or du DIDs directly to Microsoft Teams users.
• Gradual PBX Migration (Coexistence): You don't have to throw away your legacy analog, digital, or IP PBX systems. The SBC allows Teams and your legacy PBX to work side-by-side, allowing for a phased migration.
• Local Media Optimization: AudioCodes SBCs are certified for Microsoft Local Media Optimization, keeping local voice traffic within your corporate network to save internet bandwidth and minimize latency.
• Enterprise-Grade Security: The SBC provides robust encryption (TLS/SRTP), topology hiding, and protects your local voice network against cyber threats and unauthorized VoIP SIP floods.
