What is Microsoft Teams Phone Integration?
Microsoft Teams Phone Integration connects your voice calling (PSTN) to Microsoft Teams so employees can use Teams as their primary phone. Depending on your needs, we can implement:
Teams Phone with Calling Plans (Microsoft-provided PSTN)
Operator Connect (approved carrier integration)
Direct Routing (connect Teams to your SIP trunk/provider via a certified SBC)
Univision Computers will recommend the best option based on coverage, compliance, costs, call volumes, and current contracts.

Frequently Asked Questions for VOIP
What’s the difference between Teams Phone, Teams Calling, and “VoIP”?
- VoIP: Voice over IP—calling over the internet/network.
- Teams calling: The user experience (making/receiving calls in Teams).
- Teams Phone: The Microsoft service/licensing layer that enables calling features and PSTN connectivity.
Can we keep our existing phone numbers?
In most cases, yes. We can port (transfer) your numbers from your current carrier to your new Teams calling setup (Calling Plans, Operator Connect, or Direct Routing). We also help you:
- Clean up number inventories
- Avoid porting delays with proper documentation
- Plan cutovers to reduce downtime
How long does number porting take?
Porting timelines vary by carrier and the number of lines. A typical range is a few days to several weeks, depending on:
- Accuracy of your carrier account info (CSR)
- Number type (DID vs toll-free)
- Quantity of numbers and locations
We build a migration plan around your port date so business operations stay covered.
What options do we have to connect Teams to the PSTN?
There are three common models:
- Microsoft Calling Plans: Microsoft provides PSTN service (simple, quick to deploy in supported regions).
- Operator Connect: A participating carrier connects directly to Teams (often less complexity than Direct Routing).
- Direct Routing: Teams connects to your SIP trunk/provider via a certified SBC (maximum flexibility, often preferred for complex environments).
We’ll recommend the best fit based on cost, coverage, compliance, and call flow requirements.
Which is best: Calling Plans, Operator Connect, or Direct Routing?
It depends on your requirements. Common considerations:
- Calling Plans: fastest, fewer moving parts; may be limited by region/rates.
- Operator Connect: good balance of simplicity + carrier choice.
- Direct Routing: best for advanced routing, existing SIP contracts, contact center integrations, multi-site complexity, or special compliance needs.
Do we need a new phone system (PBX) if we use Teams Phone?
Often, no. Teams Phone can act as your primary phone system. Some organizations choose a phased migration where Teams coexists with a legacy PBX temporarily while departments transition.
Can we use desk phones with Teams?
Yes. You can use:
- Teams-certified desk phones
- Headsets with the Teams app (common for most users)
- Conference room devices (Teams Rooms setups)
We’ll recommend hardware based on roles (reception, warehouse, executives, call-heavy teams).
