VoIP & Phone Systems — Southern California
Your phone system, part of how your team already works.
The desk phone tethered to the office is gone. Today your phone system should live in the same app your team already uses to meet, chat, and collaborate — reachable from a laptop at home, a mobile on the road, or a desk in the office, with one number and one experience everywhere. TNS deploys and manages modern cloud calling on the two platforms that do this best: Zoom Phone and Microsoft Teams Phone.
Two great platforms. We help you pick and run the right one.
Both turn voice into part of your unified workplace rather than a separate system to manage. The right choice depends on how your team already works — and we help you make it, then handle the deployment and management either way.
Microsoft Teams Phone
If your team already lives in Microsoft 365, adding calling to Teams means voice, chat, meetings, and files all in one place, under one identity and one set of security controls. It's the natural fit for Microsoft-centric businesses — and we handle the parts Microsoft leaves to you: calling plans, carrier connectivity (Operator Connect or Direct Routing), and call-flow design.
- Calling built into the Teams app your team already uses
- One identity and security model across Microsoft 365
- PSTN connectivity via Calling Plans, Operator Connect, or Direct Routing
- Auto-attendants, call queues, and voicemail
Zoom Phone
If your team is already on Zoom, or you want the simplest, fastest phone system to roll out and use, Zoom Phone extends the familiar Zoom app to voice, SMS, and voicemail. It's known for ease of use, strong call quality, and a quick deployment — and it even integrates into Teams if you want the best of both.
- Voice, SMS, and voicemail in the familiar Zoom app
- Fast to deploy with a minimal learning curve
- Number porting to keep your existing numbers
- Integrates into Microsoft Teams where it helps
Built for how people work now.
Work from anywhere
One number that reaches your team on any device — desk, laptop, or mobile — so working from home, the office, or the road is a single, consistent experience.
- Softphone on desktop and mobile
- One number across every device
- Seamless move between call, chat, and video
- Desk phones where you still want them
Unified communications
Voice as part of the same platform your team uses to meet, chat, and collaborate — not a separate system bolted on the side.
- Calling, meetings, chat, and voicemail in one app
- Presence and click-to-call
- Voicemail and, where available, transcription
- Consistent experience for every user
Professional call handling
The features that make a small team sound like a well-run operation — routing, queues, and automated attendants configured around how you actually work.
- Auto-attendants and IVR menus
- Call queues and ring groups
- Business-hours and after-hours routing
- Shared lines and delegation
Migration & number porting
Moving from an old phone system is where most projects go wrong. We plan and execute the transition — including porting your existing numbers — so you don't lose calls or your identity.
- Existing number porting
- Planned cutover with minimal disruption
- User setup and training
- Testing before you go live
What you get with VoIP & Phone Systems.
The right platform for your team
We don't push one answer. We assess how your team works and recommend Zoom Phone or Teams Phone based on your actual needs — then deploy and manage it.
One communications experience
Voice folded into the same app your team uses to meet and collaborate, so people aren't switching between disconnected tools all day.
Truly mobile-ready
Your team stays reachable on one business number from any device, anywhere — without handing out personal cell numbers.
Handled complexity
Carrier connectivity, calling plans, dial plans, and call flows are exactly where phone projects get hard. We handle them so you don't have to.
Smooth migration
We port your numbers and cut over with a tested plan, so the switch happens without dropped calls or downtime.
Ongoing management
Adds, moves, changes, and new-hire setup handled as part of your service — your phone system stays current as your team changes.
Simple to get started.
Assess & recommend
We learn how your team communicates and where they work, then recommend the platform — Zoom Phone or Teams Phone — that fits best.
Deploy & port
We configure the platform, call flows, and devices, port your existing numbers, and test everything before a planned cutover.

We manage ongoing changes, support your users, and tune call handling as your business grows and evolves.
