Direct Routing in Azure using AudioCodes Mediant SBC Azure Edition - Part 1

This article is now out-of-date, please refer to this article for Deploying an AudioCodes SBC in Azure using the Azure Marketplace. Introduction I’ve written in the past about deploying AudioCodes SBC into Azure by using Azure Site Recovery. Whilst this works, it’s not supported! I recently asked AudioCodes if there were any plans to officially release an “Azure Edition” of the SBC and to my surprise, they said “Yes”. It’s about to hit GA, but I’ve been given a pre-release build to try. [Read More]

Test-CSOnlineUserVoiceRouting: Test a user's Online Voice Routing Policy for Teams Direct Routing

Background With the preview release of Teams Direct Routing users are now able to make and receive PSTN calls using certified SBCs instead of Calling Plans.

Teams Direct Routing and a CCE

Teams Direct Routing with an AudioCodes SBC

Introduction Last Updated: 13/05/19 Microsoft has released Direct Routing for Microsoft Teams. This is one of the big steps – in my opinion – of making parity with Skype Online. Direct Routing effectively allows you to connect up existing PSTN connectivity (e.g. SIP trunks) into a certified SBC and route directly to Teams. This differs from the Skype Online method of doing this, in that you no longer need any hardware (on-premises Skype for Business Server or a CCE) other than an SBC. [Read More]

One Liner: Check if a PSTN number is blocked in Skype Online or Teams

Recently added to Skype Online and Teams is the ability to block inbound calls based on their caller ID. Useful for blocking nuisance callers. Once you’ve added the patterns, you ideally want to know: If the calling numbers you want to block will be caught in your patterns. Regex is not my strong suit so want to make sure it will match. Are some calls going to be inadvertently blocked? [Read More]
