One project I have been working on recently at Symity is a global roll out of Teams Direct Routing. This has resulted in SBCs being installed in different configurations based on local connectivity and requirements. One such requirement is where sites have multiple internet connections for resilience - can the SBC make use of this? It makes perfect sense especially when using cloud-based service – if one ISP has an issue, you want to be able maintain service with the other.
This article will assume you already have Teams Direct Routing in place. If you are not there yet, consider looking at my article on this subject: https://www.lee-ford.co.uk/teams-direct-routing-with-an-audiocodes-sbc/ Introduction to Media Bypass A welcome addition to Teams Direct Routing is Media Bypass. Before Media Bypass was released, all media when using Direct Routing would need to route up to one of six regional Teams Media Processors and back even if the Teams client and SBC were in the same location.
Introduction Following on from Part 1, you should now have an AudioCodes SBC up and running in Azure. This article will cover any Azure specific setup to allow Teams Direct Routing to function. For Direct Routing configuration you can follow my earlier blog post for instructions. Note: In Azure, we are using a single NIC, so the “LAN” and “WAN” NIC mentioned is the same interface, so bear this in mind when configuring Media Realms, SIP interfaces etc.
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. Part of setting this up involves setting up PSTN Usages, Voice Routes, Online Voice Routing Policies, PSTN Gateways etc. within Skype Online PowerShell. Much like Skype for Business, if your users have multiple calling requirements the amount of Voice Routes, PSTN Usages etc. can grow quickly and sometimes make it quite hard to fathom how a call will route.
Just a quick one here. I was busy setting up some Voice Routes and Online Voice Routing Policies for Direct Routing but it wasn’t behaving as I expected. I had purposely locked down my account I was using to only allow UK calls. But when making a call to Microsoft US, it worked. Odd! I double checked the routing I had in place and it was correct. Strange… I then made sure I didn’t have a Calling Plan assigned (as that will be used as a last resort)… I didn’t.
Last Updated: 13th August 2020 Introduction Microsoft has released Direct Routing for Microsoft Teams. 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. In this post, I’ll go over how to do this with an AudioCodes SBC and SIP trunks.
