Frequently Asked Questions

Working with a provider like ULTATEL, means that the solution has been tested and certified by Microsoft and that gives you the peace of mind that your Microsoft Teams Integration will work exactly how you want, and with the highest level of security and customer support possible. An SBC protects and regulates IP communication, between your Teams tenant and your voice service providers' network. Simply put, the Microsoft-certified SBC means that Microsoft has:

  • Jointly worked on the SIP interconnection protocols
  • Performed intense tests using a 3rd party lab
  • Run daily tests to guarantee new versions of Direct Routing code will work
  • Established a joint support process with ULTATEL

ULTATEL is partnered with Microsoft and is one of the very few selected providers who has had their SBC, which protects and enables calling to the outside network from Microsoft teams, actually tested and certified directly by Microsoft. ULTATEL also takes you from innovation to celebration by providing custom solutions like the ability to send SMS text messages directly from your Teams platform to any SMS-enabled phone number.

With several Teams solutions such as Sip Trunking/ Direct Routing, an integration with ULTATEL's intuitive and powerful cloud phone system, full Teams Migration Support, as well as Microsoft certified SBC's services for enterprises and providers, ULTATEL is the Microsoft-certified Industry-Trusted Partner you can trust for your team’s needs.

You don’t need much to get started with Microsoft Teams Calling:

  1. A Microsoft Phone System license comes included with the E5 package of Microsoft 365 and can be added to E1 or E3. Your ULTATEL onboarding specialist can help guide you if needed.
  2. A service provider like ULTATEL can provide SIP Trunks or Direct Routing for Teams. You can transfer or port your existing phone numbers to ULTATEL or have new ones provided
  3. A Microsoft-certified SBC like ULTATEL's to protect and bridge Teams connection to the Public Network. The SBC acts as a voice firewall and translator between the two environments and types of communication such as media bypass
  4. A point of contact for your organization to work with during the integration

You need an SBC to work as a bridge between Microsoft Teams and the telephone network but how come?

  • Protection & Security – An SBC encrypts traffic to keep any unauthorized access from entering the data network via the voice network
  • Performance – ULTATEL’s Microsoft-certified SBCs adjust key parameters to ensure your Sip Trunking connection is always functioning properly with no hassle
  • Convenience – Want to gradually move to Teams at your own pace? ULTATEL’s Microsoft-certified SBCs can provide simultaneous ringing so that both Teams and your old PBX share connectivity.
  • Continuity – ULTATEL’s SBCs have failover solutions that keep your organization connected even if the unexpected happens.

Direct Routing for Microsoft Teams allows you to make and receive business phone calls
Microsoft Phone System Direct Routing is the service inside of Teams that allows organizations to connect external phone lines and use Teams as a Unified Communications Platform. Organizations are already using Teams for file sharing, video conferencing, and chat; adding voice to streamline your tools just makes sense.

Teams uses SIP Trunks or IP-based voice connections to connect to the Public Telephone Network or anyone outside your organization. ULTATEL’s Microsoft certified SBC is necessary to connect Teams to either ULTATEL or another communications service provider (aka phone lines). ULTATEL’s Microsoft-certified SBCs protect and secure these connections and ensure future compatibility and performance, so you have the option to select from hundreds of service providers across the globe.

Enable Direct Routing for Microsoft Teams from the Azure Cloud or Amazon Web Services (AWS)

Using Teams for video conferencing, chat, and file-sharing has become the norm for over 100 million users and 93% of the Fortune 100 companies. Now ULTATEL makes it possible to enhance those capabilities and streamline the tools you have to manage on a day to day basis by securely connecting Teams to the external telephone network.

Depending on needs, organizations can slowly migrate off a legacy PBX or immediately move some or all of their business phone calls to Teams. Users can make and receive calls from almost anywhere, on any device so everyone can stay connected and productive.

ULTATEL Microsoft-certified SBC makes it all possible. Azure or AWS cloud provides a secure bridge between your enterprise network and a Service Provider (CSP), like ULTATEL with no hardware to deploy or manage. With the flexibility to scale up or down as needed, you can be operational and ready to go in minutes. Try us out for free for 30 days and see for yourself.

  • No hardware to install
  • Microsoft-certified SBC
  • 30-day no-risk proof of concept
  • Full media services
  • Flexibility to choose your or phone or service provider
  • Ultimate security to protect your voice and media communications

For many organizations, the migration to Microsoft Teams Calling is not merely a matter of flipping a switch. If you are in a multi-year contract with your Cloud UC service, have investments in an existing IP-PBX, or have complicated business workflows, the switch to Teams may be a little more complicated.

ULTATEL gives organizations the flexibility to integrate everyone into Teams or just certain groups or individuals.

Keep your existing PBX or Cloud UC solution in-place and maintain existing relationships. Organizations can integrate 1 user or 10,000 users to Teams. The user's PBX phone and Teams client (desktop or mobile) will ring simultaneously, even if they are part of a group on the PBX. Stay connected in the office, at home, or on the road. Users can place outbound calls from either client, and the far end will always see the office caller ID. And if a user is on the phone, it's noted on both systems.
