Setting up tag based routing in Audiocodes Mediant

2021-02-24 2 min read Audiocodes Microsoft Teams "Erwin Bierens"

In this post i want to show the configuration steps of configuring tag based routing.

You can use Dial Plan tags for determining the destination (IP Group) of an IP-to-IP Routing rule. One of the advantages of using Dial Plan tags is that it can reduce the number of IP-to-IP Routing rules that you would normally need to configure.

For example: When you have an SBC with SIP trunk and legacy PBX and you would like to implement Microsoft Teams Direct Routing you can route specific numbers to Teams and the rest goes automatically to the legacy PBX. This way you can migrate your users in steps to Microsoft Teams.

Troubleshoot No Dialpad in Microsoft Teams

Everytime i roll out new customers with Microsoft Teams Direct Routing or Callings plans i receive the same questions. I also created a FAQ post about Direct Routing.

And the most asked question during roll out is:

I don’t have a dialpad in my Teams client

No DialPad

Licenses

Ok, first check if this user has the correct licenses. Phone System is required for calling. This license is by default included with E5, any other license needs Phone System as addon.

Validate Routing to Microsoft Teams Resource Account

When you use Auto Attendants and Call Queues to route phone calls you want to verify sometimes if the routing is working correctly and the calls are being delived to the right Resource Account.

You can easily check this in the SIP invite. I’m working mostly with Audiocodes so the screenshots below will be based on the Audiocodes Syslog tool.

Open the call in the syslog trace. Sip Invite

Select the second invite to Microsoft Teams (52.114.75.24) Sip Invite2

Choosing the right Teams IPPhone Policy

In this article i want to show the different capabilities of the Microsoft Teams IPPhone Policy. Do not get confused with the SfB IPPhone Policy, this one only controls the global policy and it’s not possible to create your own.

The Microsoft Teams cmdlet Set-CsTeamsIPPhonePolicy is only available in PowerShell. When logging in to your Tenant you can check which cmdlets are available.

Get-Command -Module tmp_3ju02ihp.npo | Where-Object {$_.Name -like "*TeamsIPPhone*"}

Use the temp module name in above cmdlet.

“Public Preview for Microsoft Teams provides early access to unreleased features in Teams. Previews allow you to explore and test upcoming features. We also welcome feedback on any feature in public previews. Public preview is enabled each Teams user, so you don’t need to worry about affecting your entire organization.”

Transcoding issue on the Audiocodes Mediant

2020-12-03 2 min read Audiocodes Microsoft Teams "Erwin Bierens"

I have had a issue with a customer where we have implemented Direct Routing. It’s a HA setup version 7.20A.260.095 running virtual on a VMware cluster.

The alarm says: License Pool Alarm. Some of the license pool allocations exceed maximum capability and will not be applied.

In the syslog i see the followig errors show up:

            20:11:35.145  172.20.1.1  local0.warn    [S=3603724] [SID=815d0e:57:143476]  (N  3305189)!! [ERROR] ResourceCounter: Cannot allocate more Media channel [0/0] [Time:23-11@20:11:36.770]

When i look in to my license i have transcoding assigned by the OVOC, but they are not allocated:
