Modern cloud phone with messaging built in. Teams integration that goes beyond direct routing. Full contact center when you grow into it.
One platform, one data model, one team to support it, from a single phone line to a full call center. Every conversation runs through the same AI, the same PSA integration, the same dashboard.
1Stream Voice & Messaging is a complete cloud communications stack for MSPs: voice, SMS/MMS, video, contact center, and native Microsoft Teams, all on a single platform with one number for calls and texts. Every channel shares the same PSA and RMM integration layer and connects to the same seven AI agents, so context follows the conversation across every channel.
Most MSPs we talk to are running voice through one vendor, SMS through Twilio, Teams through Microsoft, and a chat widget from somewhere else. Each tool has its own ticket pop, its own reporting, its own login. Customer history lives in five places, or nowhere.
When a tech answers a call, they don't know that customer just texted 20 minutes ago. When a manager pulls a CSAT report, they're stitching it together by hand. When AI tries to understand the conversation, it only has a fraction of the context.
1Stream runs every channel through the same platform, same data model, same AI agents, same PSA integration. The result: every conversation has the full context of every other conversation.
Start with a single phone line. Grow into a full contact center. Run inside Microsoft Teams. Same platform, same data, same support team, whatever scale you're at.
A modern cloud-native phone system that includes voice, video, SMS, MMS, and chat, one platform, one number for calls and texts, one data layer powering AI and PSA integration.
Make and take calls from anywhere, desktop, mobile, browser, or hardphone. Texts thread alongside calls in the same inbox. Texts and voice share the same number. No separate "messaging vendor."
Most "Teams Voice" vendors give you direct routing, basically just PSTN dial tone inside Teams. We give Teams users the full UCaaS and CCaaS feature set right inside the Teams client.
Skill-based routing, queue callbacks, supervisor barge/whisper, real-time wallboards, AI Attendant, call recording, PSA integration, all working natively inside Teams. Your team works in the tool they already live in; the platform works underneath.
When call volume grows beyond simple call queues, the same platform delivers full contact-center capabilities. No re-platforming, no second product, no separate vendor.
Skill-based ACD that routes by tech specialty. Queue callbacks so customers hang up but keep their place in line. Real-time wallboards and supervisor barge/whisper/coach. SLA tracking with automatic breach alerts. Omnichannel routing that pulls voice, SMS, chat, and Teams calls into one queue with priority rules you define.
Outbound dialing built into the same platform, not bolted on. Two distinct use cases that your existing UCaaS or contact-center vendor probably can't handle:
We work with technical people. Most of our support calls are walking new admins through the portal for the first time, not unblocking issues. The platform is built so you can actually run it.
Traditional carriers and UCaaS vendors make you complain through three levels of support to get anything actually done on your account. That's not how MSPs work.
1Stream gives you a real multi-tenant control plane. Manage every client's system, extensions, call flows, integrations, and storage from one portal. Add a user. Change a routing rule. Provision a phone. Pull recordings. Without opening a ticket.
Our support team is always there when you need us. But we built the platform so you mostly won't.
Any open SIP phone works. Yealink, Polycom, Cisco, Grandstream, Snom, we don't lock you into proprietary handsets. Your existing inventory likely just re-provisions.
Our session border controllers live at the datacenter, not in your client's closet. Nothing to install, maintain, patch, or replace at end-of-life. Site closets stay clean.
Phones light up and work. MAC address registers, configuration pushes automatically, extension is live. Drop-ship to a remote site and it provisions itself when plugged in.
Multi-tenant management means your jr techs can run the day-to-day. Add users, change call flows, pull recordings, manage integrations. No dedicated phone expert required on staff.
Phone systems can't fail the way SaaS apps fail. When voice goes down, businesses stop. We engineer for that reality.
Geo-redundant infrastructure across multiple data centers. Tier-1 carrier relationships. Active-active failover. Real-time monitoring. And if something does go sideways, you call our support team, not a chatbot, and a human who built this platform answers.
Any vendor can sell you voice and SMS. The reason 1Stream is different is the platform underneath every channel.
Every channel runs through the same 7 AI agents. Caller verification, smart routing, auto-notetaking, sentiment scoring, works on voice, text, chat, Teams.
Voice talks to your PSA. SMS pulls from your CRM. Teams calls update your tickets. Every channel is integrated with the tools you already run.
One BI dashboard across every channel. See call volume next to chat volume next to SMS volume. CSAT and SLA across all touchpoints, not stitched together.
Run the math on your team's call volume. See exactly what you'd save in hours, dollars, and FTE-equivalents, before consolidating, before adding AI.
Run the reclaim calculator →Most MSPs we talk to have these worries. Real answers, no carrier-speak.
Yes, this is the question that scares every MSP and we take it seriously. Here's how it works: we provision your numbers in parallel on our network before the porting cutover. Test calls work end-to-end on day one. The actual port window is typically a 30-minute coordinated cutover with the losing carrier.
If something goes sideways during the port (rare but possible, usually losing carrier delays), the existing service stays active. You don't lose calls. We've ported tens of thousands of numbers; our team handles the carrier paperwork end-to-end.
HD voice with G.722 / Opus codecs. We monitor MOS (Mean Opinion Score) on every call, the industry standard for voice quality, and target 4.0+ across the board.
For real-world performance: most call quality issues come from the customer's network, not the vendor. We provide diagnostic tools that test bandwidth, jitter, and packet loss on your side so issues can be diagnosed instead of blamed on "the phone system."
Full compliance with both. Kari's Law: 911 calls work without dialing 9 first. RAY BAUM's Act: dispatchable location is automatically transmitted with 911 calls so first responders know exactly where to go, including which floor and suite in a multi-tenant building.
For MSPs, this also means your end-clients get Kari/RAY BAUM compliance through your service automatically, no separate e911 vendor required.
Most likely yes. We support every major SIP handset brand, Yealink, Polycom, Cisco, Grandstream, Snom, etc. If your phones are SIP-based and not locked to a previous carrier's firmware, we can re-provision them. We'll audit your existing inventory before quoting so you know exactly what's reusable.
Global termination supported. Local numbers in 60+ countries. We can quote per-minute international rates by destination, or set up "international bundles" for MSPs supporting clients with regular overseas operations. Talk to us about your specific destinations.
Most "Teams Voice" vendors just sell you direct routing, PSTN dial tone connected to Teams. That's it. Your team gets a phone number inside Teams, and the rest of the platform features (queues, supervisor tools, recording, AI) live somewhere else, in a different app.
1Stream gives Teams users the full UCaaS and CCaaS feature set inside Teams. Skill-based routing, queue callbacks, supervisor barge/whisper/coach, real-time wallboards, AI Attendant, call recording, PSA integration, all working natively without leaving Teams.
This matters for two reasons. First, your techs only have one app open. Second, you don't pay Microsoft Calling Plan rates, you pay our rates, and you get the platform features, not a stripped-down version.
Multi-tenant by design. Each end-client gets their own tenant with their own numbers, users, settings, and billing. You manage them all from one parent dashboard. Full white-label options available, clients can see your branding instead of 1Stream's. Margin and pricing are yours to control.
Softphones, certified desk phones, DECT, conference rooms, gateways, the full list, with support levels.
