Teams Direct Routing with Mediant VE Audiocode SBC (Part1)

This article (part1) will be helping you using your Azure subscription , to deploy a mediant VE SBC audiocode , and configure your tenant with direct routing connexion .

First of all we need to deploy our SBC on Azure :

to do that you need to have a subscription on your tenant : Log in your azure portal using the url : https://portal.azure.com/

then go to Subscription :

aften confirming that you have a valid subscription ; go to create new ressource :

then search for Audiocode Mediant VE :

click on create and then go through the basic configuration :

in the network configuration for my lab , i chose two network interface ( 1 for Teams and 1 for PSTN trunk) ; this how my deployement results look like :

from your SBC perspective you have a public IP adress and a lot of other informations :

to be able to create a new pstn getway on your tenant /SBC , you need to do two main configurations :

the first one is giving a FQDN to your public ip adress ;i will use my manager

dns records to do that; using a type A dns record :

second thing to do is to verify this fqdn on our tenant , to do this , let go to

you can then add your domain and verify it using different Dns record ( dont forget to create a user with at least a E3 licence using this new fqdn , if you dont do that , it won't work)

let's try connect to this fqdn and login using the user/Password with chose in the azure mediant deployement :

we have then access to our gui interface of our SBC mediant VE

Teams Direct routing configurtion :

you have two ways to configure your direct routing , the first one is the TAC : Teams Admin Center :

i chose for my lab , to do that through Powershell Commands ; this is a full example that you can modify and use :

$sbcDR = 'sbc*.*******.com'
