In short

1Stream’s Microsoft Teams integration brings real PSTN calling into the Teams client your clients already use, through hybrid direct routing. Calls run on 1Stream carrier-grade voice, and when a call ends the AI posts a summary, sentiment, time entry, and recording to the PSA. Clients keep Teams. You get the voice and the automation behind it.

Teams Phone alone vs Teams plus 1Stream

Teams Phone is dial-tone. 1Stream is the phone system.

01

Keep Teams as the app

Users place and answer calls right inside Microsoft Teams. Nothing new to learn, nothing to migrate.

02

1Stream powers the calling

Hybrid direct routing connects Teams to carrier-grade voice. One provider, one partner experience, no juggling carriers.

03

Everything logs to the PSA

Every call lands in the PSA with an AI summary, sentiment, and a time entry. The same automation as the rest of 1Stream.

Why MSPs run it

Real voice, zero disruption.

No rip and replace

Clients keep the Teams app and every habit around it. You add carrier voice and integrations underneath, with nothing to relearn and no migration project.

Carrier-grade calling

Reliable PSTN voice on 1Stream infrastructure with tier-1 carrier peering, not a best-effort, over-the-top add-on. Call quality your clients can build a day around.

PSA auto-logging

Every call posts to Autotask, ConnectWise, or HaloPSA on its own, with the summary and time entry attached. The desk stops writing notes by hand.

AI on every call

Issue, fix, and result captured automatically, with sentiment and a time entry, before the next call rings. Your techs get the minutes back.

One partner experience

One provider, one bill, one place to manage voice across your whole client base. No carriers to juggle and no finger-pointing when something needs attention.

Built for MSPs only

Sold exclusively through MSPs since 2014, never direct to your clients. Your brand stays in front of the relationship, always.
