Teams-first organizations
You already use Teams for internal chat and meetings and want external calls in the same place.
Fit check
Teams calling is a great fit if you live in Microsoft 365.
If your staff already spends their day in Outlook, Teams, and SharePoint, moving voice into Teams can simplify life — when it’s designed properly.
Hybrid & remote teams
Staff split between office and home, and you need a consistent way to reach everyone.
Growing SMBs
You expect to add users and locations and don’t want to keep rethinking your phone setup.
Options
Three ways Nova can bring calling into Microsoft Teams.
We’ll walk through the pros, cons, and costs of each approach with you. Here’s the high-level view to get you oriented.
Direct Routing
Connect Nova-provided SIP trunks to Microsoft Teams so Teams becomes your full phone system, using your existing numbers.
- Best for organizations ready for Teams to be the primary phone system.
- Uses Microsoft Teams Phone licenses and Nova-managed trunks.
- Great fit for 20–250 user environments.
Teams-integrated PBX
Keep your existing Zultys-based PBX as the core phone system and integrate it with Teams for specific users and use cases.
- Best for organizations with complex call flows or existing investments.
- Lets you adopt Teams voice gradually, without ripping out what works.
- Flexible for contact centers and specialty extensions.
Hybrid & phased approaches
Start with certain departments or locations in Teams while others remain on traditional endpoints, then phase over time.
- Aligns with your licensing, budget, and change tolerance.
- Minimizes disruption to high-volume or sensitive lines.
- Gives you time to see how Teams voice works for your staff.
Side-by-side
Which Teams calling approach fits you best?
Use this high-level comparison as a guide. We’ll confirm the details based on your Microsoft 365 licensing, call flows, and locations.
| Option | Best for | Pros | Considerations |
|---|---|---|---|
| Direct Routing | Teams-centric orgs (20–250 users) | Single app, simplified management, strong fit with Microsoft 365 security. | Requires Teams Phone licensing and readiness work on your network and tenant. |
| Teams-integrated PBX | Existing Zultys customers or complex sites | Protects existing investments, rich call features, great for contact centers. | Two systems to coordinate; needs a partner who knows both worlds. |
| Hybrid / phased | Change-averse teams or large rollouts | Gradual migration, lower risk, easier end-user adoption. | Requires a clear roadmap so you don’t get stuck in “forever hybrid.” |
Implementation
We handle the details — from licensing to dial plans.
Teams voice projects cross between IT, operations, and finance. Our job is to translate all of that into a clean, step-by-step plan your team can understand.
- Review your current phone setup, call flows, and Microsoft 365 tenant.
- Confirm licensing requirements and recommend the right Teams voice model.
- Design call routing, auto attendants, and failover plans.
- Configure trunks, policies, and dial plans in collaboration with IT.
- Plan and execute the cutover, with staff training and live support.
Experience
A Teams partner who also understands phones.
Many Microsoft partners know licensing and cloud. Fewer know dial tone, call flows, and what happens when the internet hiccups. Nova sits at that intersection.
Thousands of systems deployed
We’ve implemented more than 4,000 business voice systems across offices, clinics, and multi-site organizations.
Zultys & Teams expertise
We understand both the PBX side and the Microsoft side — and how they need to work together.
Real-world cutover plans
We plan migrations around your busy hours so you’re not testing new phones during your peak call windows.
Questions
Common questions about Teams calling with Nova.
Do we need E5 licenses to use Teams calling?
No. There are multiple ways to license Teams voice. We’ll review your current plan and map out the most cost-effective path.
Can we roll this out to one department first?
Yes. Many customers start with a pilot group or single department before moving more users over.
What if we decide Teams calling isn’t for us?
We’ll be transparent about tradeoffs up front. If we don’t think Teams calling is the right fit, we’ll say so and recommend alternatives.
Who supports us after go-live — Nova or Microsoft?
Nova remains your first call. We’ll coordinate with Microsoft or other vendors as needed behind the scenes.
