Poor User Experience

Increased Complexity

Security Risks

IT teams must ensure each of your systems is properly secured, patched, and updated to keep your network safe from vulnerabilities.


Limited Integrations

When Microsoft Teams can’t easily connect with other communication systems, it makes it harder to share information. This can cause delays and errors.


High Costs

Managing separate systems costs more due to added licenses, subscriptions, maintenance, and training.


Lack of Customization

Customizing separate systems and applications to work together can require using external resources or dedicating internal IT effort.

Productivity Factors

Organizations are leveraging Microsoft Teams for internal messaging, collaboration, and meetings, while still relying on separate phone systems to communicate with external stakeholders. However, this fragmented approach can result in various productivity limitations and drawbacks. 

With UniVoIP’s Native Teams calling, leveraging the Microsoft Teams Phone System and the MS Teams client for calling, all of the challenges and issues noted below will be eliminated. Users' experience will be seamless, training will be substantially minimized, admin onboarding and management will be rapid and easy, and security protocols will be addressed and inherent:

  1. Fragmented User Experience: Switching between different platforms can create a disjointed user experience for employees. They must juggle between Microsoft Teams and the separate communications system, leading to potential confusion and inefficiency. With UniVoIP’s Native Teams calling, the user experience is seamless. The user will never have to leave the Teams client or engage a 3rd-party app for calling and therefore will enjoy true Unified Communications.
  2. Limited Integration: The lack of integration between Microsoft Teams and the external communications system can hinder seamless information sharing and collaboration. It may require manual processes to transfer information and communication between the two systems, leading to potential delays and errors.
  3. Increased Complexity: Managing and maintaining two separate systems can introduce additional complexity and administrative overhead. IT teams need to handle multiple systems, user accounts, licenses, and configurations, which can be time-consuming and resource intensive.
  4. Communication Barriers: Using a disparate communications system for external stakeholders can create communication barriers and potential misunderstandings. Different features, functionalities, and interfaces between the two systems may lead to difficulties in establishing effective communication channels with external parties.
  5. Potential Security Risks: Maintaining multiple communication platforms can increase the overall security risks. IT teams need to ensure that both systems are properly secured, patched, and updated, which can be challenging and may introduce vulnerabilities.
  6. Inefficient Workflows: Separating internal and external communication systems can disrupt workflows and hinder collaboration. It may require employees to switch between different platforms, resulting in slower response times, decreased productivity, and potential miscommunication.

Cost Considerations

Maintaining two separate communication platforms, such as Microsoft Teams for internal use and a disparate system for external stakeholders, can indeed lead to increased costs. With UniVoIP’s Native Teams calling, leveraging the Microsoft Teams Phone System and the MS Teams client for calling, the cost-related factors below will be substantially reduced:

  1. Licensing and Subscription Fees: Each platform typically requires its own licensing and subscription fees. By using two separate systems, the organization incurs additional costs to maintain both platforms.
  2. Infrastructure Costs: Running and maintaining multiple communication platforms may necessitate additional hardware, software, or cloud infrastructure resources. This includes servers, network infrastructure, storage, and backups, leading to increased expenses.
  3. Training and Support: Training employees to use and manage multiple communication platforms can be time-consuming and costly. IT staff may need additional training to support and troubleshoot issues on both systems, adding to the overall expenses.
  4. Integration and Customization: Integrating and customizing two separate systems to work together seamlessly often requires additional development and configuration efforts. This can involve hiring external consultants or dedicating internal resources, resulting in increased costs.
  5. Administration and Maintenance: Managing two communication platforms means allocating resources for administration, maintenance, and updates for both systems. This includes user management, security measures, software upgrades, and bug fixes, which adds to the workload and costs.
  6. Third-Party Integrations: If other tools or services need to be integrated with both communication platforms separately, there may be additional costs associated with licensing or development efforts to ensure compatibility.

It’s important to note that specific licensing and configuration requirements may apply, and organizations should consult with Microsoft or a Microsoft Solutions Partner, such as UniVoIP, to determine the most suitable Teams phone system connectivity option for their Teams deployment.

If you’re already using Microsoft Teams for collaboration but want to improve efficiency and cost-savings by making, receiving, and transferring voice calls within the Teams client, you’re the right fit.

Here is a summary of licensing requirements for Teams voice/phone system. This is needed for users to be able to have a number assigned in production and make/receive external calls. 


Users must have a Teams-inclusive Microsoft 365 user license. Nothing else is needed if the user license is an E5 or equivalent. For lower Enterprise licenses as well as Business user licenses and below, the user must have a Teams Phone Standard add-on license. So, if anyone has an E1, E3, or Business Basic/Standard/Premium user license in your environment they will need the Teams Phone Standard addon license to have voice activated.  


Additionally, you will need at a minimum one Teams Phone Resource Account license per voice application (Automated Attendants and Call Queues). This is a free license. You can start with 20 and add more as needed. 


To support common area phones, you may use Teams Shared Device License. This gives you the same functionality as the Teams Phone Standard license. The difference is that the Teams Shared Device License is a stand-alone license and doesn’t require a base user license. 


To add audio dial-in capability to Teams conferencing, you may add a free license to every Teams user. That license is called Teams Audio Conferencing with dial-out to USA/CAN. This license is independent of Teams Voice and is not required. 


Please be aware that in the initial phase of the UniVoIP automated onboarding process, the application necessitates either an unallocated Phone Resource account or an E5 user license. Alternatively, an unallocated Teams inclusive user license (ex: E1, E3, Business Basic/Standard/Premium) along with an unallocated Teams Phone Standard addon license will suffice. The unallocated license(s) are for temporary use and will be returned to the license pool upon the completion of the onboarding process.


We're here to assist you with any licensing questions you may have, so don't hesitate to reach out if you need clarification.

Calling and Meetings in Microsoft Teams

Remember to regularly check these resources for updates and new materials.

Microsoft Teams Certified devices are peripherals such as headsets, speakerphones, webcams, and monitors that offer rich audio or video quality. These devices work (plug & play) with no extra configuration required, and offer call control with Microsoft Teams and Skype for Business. Certified devices provide a great experience for end users and administrators. They are tested and certified by Microsoft to ensure that they offer the best possible integration with Microsoft Teams1.

On the other hand, Microsoft Teams Compatible devices are devices that are not certified by Microsoft but are still compatible with Microsoft Teams. These devices may require additional configuration and may not offer the same level of integration as certified devices.

What is Outbound Caller ID Name (CNAM)?


The Caller Name (CNAM) is a feature that displays your Name or Company Name on the Caller ID display of the party you are calling. When it is set up, your Caller ID Name will display as text along with your Caller ID Number.

As CNAM transmission is the responsibility of the terminating carrier (the number being called), that terminating carrier must support CNAM functionality and must have updated CNAM Database records. 

How do I set up my Outbound Caller Name (CNAM)?


Your contact name is used for CNAM as default on all telephone numbers.  You can create new names for CNAM on our Service Control Portal and assign telephone numbers to them.  Contact your Service Delivery Professional or UniVoIP Support Team for more information on how to create new CNAM assignments.

How long would it take for my CNAM to be activated? 

Allow a 72-hour update window; however, it may take weeks to get the National Registry updated. Local carriers in the United States perform a “dip” to get a new list of CNAM matched to numbers.
