3 Ways To Connect Cisco Jabber And Microsoft Teams

Learn how to seamlessly connect Cisco Jabber and Microsoft Teams for unified communication, including Jabber calling integration within Teams and integrating Cisco Call Manager with Teams to facilitate cross-platform communication.

When you’ve got legacy users who need to communicate with new remote users, it’s time to connect Cisco Jabber and Microsoft Teams.

You might have been a Cisco house since the introduction of your PBX or telepresence solution many moons ago. But, upon moving to remote working, you’ve now got pockets of Microsoft Teams users who need to chat with your Jabber users.

It might also be the case that you use Jabber and are moving to Webex in the near future. But your suppliers, contractors, and clients all use Microsoft Teams.

Instead of switching between apps or resorting to email to accommodate them, wouldn’t it be great if you could stay in Jabber and chat with those Microsoft users?

In this post, we cover all the ways you can connect Jabber and Microsoft Teams:

  1. Cisco Jabber calling integration for Microsoft Teams
  2. Microsoft Teams Cisco Call Manager integration

1 – Cisco Jabber calling integration for Microsoft Teams

Cisco Jabber encompasses all forms of unified communications into a single app. Jabber has voice, video, messaging, and conferencing capabilities. People across the organization can collaborate using this app on their device of choice.

Businesses that have already invested in Cisco Unified Communications (CUC) want to maximize their investment for the future.

Jabber offers the advantage of using CUC infrastructure. It can seamlessly move from a chat, to a call to external numbers or SIP addresses – thus providing business-quality video and voice.

Cisco Jabber app is straightforward and intuitive, whether you are using it from your desktop or phone.  

Organizations with internal groups, or external vendors using Microsoft Teams can easily integrate Cisco Jabber without having to overhaul the complete system.

The Jabber app can be used on your desktop, android device, iPhone, and iPad. Starting a call is easy from the chat window for all of the devices. Additionally, you can assign speed dials and use the keypad to call people on a desktop.

Using the Jabber app within Microsoft Teams

Microsoft Teams is a chat-centered workspace in Microsoft 365. The Teams client can be  installed on any device and the functionality of Jabber on Teams remains almost the same across all devices.  

The Cisco Jabber application needs to be installed in the desktop/ mobile device on which the Teams application is running.

Jabber only works with Microsoft Teams’ cloud-based solution and doesn’t have an on-premises offering.

How to configure Cisco Jabber for Microsoft Teams

The Cisco Jabber app needs to be allowed from the Microsoft Teams Admin Center. Users can then install Jabber from the “Apps” section of their Teams client.

As an Administrator:

  • Log in to Microsoft Teams Admin Center
  • Click on Teams Apps > Manage Apps, from the menu on the left
  • Search for Jabber in the search box. Click on the app name in the search results
  • Toggle on the app status to allowed
  • From the menu on the left, go to Teams apps > Permission policies
  • Select the policy for your organization, and make sure Third Party apps are set to Allow all apps
  • From the menu on the left, select Teams apps > Setup policies
  • Select the policy for your organization
  • Click Add > Add Apps, then search for Jabber and click Add
  • Click Add at the bottom of the screen to confirm
  • Click Save

If you’re an end user, here’s how you install the Jabber app on your Teams client:

  • After launching Teams on your desktop/ laptop, go to Apps on the left panel of the Teams window.  
  • Search for Jabber
  • Click on “Jabber” and then hit “Add”
  • After installation the Jabber app will show up on the left panel of the Teams window

Cisco Jabber features in Microsoft Teams

With the Cisco Jabber app, you can dial an extension via the keypad, search your contacts, and also save your personal speed-dial list.

  • You can search for a contact from the search box listed under “Make a call”
  • You can also use the dial-pad to make calls if you know the number/ extension
  • Speed-dials can be configured by clicking on the “Add a speed dial” button on the upper right-hand corner of the screen
  • A pop-up window will appear where you can enter a name and a number that you would like to save for the speed dial
  • Click Add to save it to your speed dials list

2 – Microsoft Teams Cisco Call Manager integration

Integration between Cisco Call Manager and Microsoft Teams can help you get the best of both worlds. Especially if you have users on both of these unified communications platforms, who need to talk to each other.

The challenge when two independent phone systems are merged is replicating the extensions and dial plans of the two systems. This could get out of hand when dealing with a growing organization.  

Configuring Single Number Reach (SNR) on both CUCM and Microsoft Teams in this scenario is an apt solution. It facilitates calls landing on a mobile number to ring simultaneously on a Cisco extension or a phone connected to Microsoft Teams and vice versa.

Thus eliminating the need to replicate dial plans or extensions of one system into another.

Here are two ways of integrating Microsoft Teams with CUCM.

Integrating Cisco call manager with Microsoft Teams using a SIP gateway


  • CUCM
  • Microsoft Teams
  • PSTN Gateway
  • SIP Gateway

How It Works:

In this scenario, a SIP gateway connects the Teams environment to the CUCM. The CUCM is also connected to a PSTN gateway to route calls to and from the outside world.  

Once call routing is configured on both CUCM and Teams, users from both environments can communicate with each other.

Users on both systems can also use the PSTN gateway to reach/ talk to DID’s outside the CUCM / Teams environment. Here the external call handling is controlled by the Call Manager.

Direct Routing to integrate CUCM and Microsoft Teams

You can connect Microsoft Teams to Cisco Call Manager using a Session Border Controller (SBC) that is supported by Microsoft. The SBC could be a Cisco Unified Border Element (CUBE) or any compatible hardware from other manufacturers.

In the Microsoft world, this is called direct routing.

A detailed configuration is available beyond the scope of this article here.
