A Cloud Business Phone System That Actually Replaces Your PBX
Extensions, IVR, queues, recording, voicemail-to-email, 911 —” on a US carrier network with Microsoft Teams dialing built in.
Everything a modern business phone system should be
User extensions and direct numbers
Every employee gets an extension and a DID. Internal calling is free.
Multi-level IVR and auto attendant
Route callers by skill, department, language, or time of day — feeding directly into call queues and overflow rules.
Call queues and ring groups
Skills-based routing, queue callbacks, wait-time announcements, and overflow rules — core capabilities of any compliant business VoIP deployment.
Call recording
On-demand or automatic. Stored with encryption, searchable by keyword with AI transcription.
Voicemail-to-email
Voicemails arrive as MP3 and text transcript in your inbox.
Business SMS from your main number
Customers text the same number they call.
911, CNAM, and STIR/SHAKEN
US emergency routing, outbound caller ID name, and carrier-level spam attestation — standard.
One number. Every device your people already use.
Desktop softphone, iOS and Android mobile apps, desk-phone compatibility (Yealink, Poly, Cisco), and native Microsoft Teams dialing — all sharing the same extension, voicemail, and directory. Our deployment approach follows the FCC VoIP guide for compliant business communications.
Lift your PBX off IT's shoulders — without a service interruption
On-premise PBX hardware dies, support contracts expire, and every move-add-change becomes a ticket. Teloz moves all of it to the cloud, port by port — including AI transcription for every recorded call.
- Hardware dies mid-quarter
- Support contracts expire
- Every move-add-change is a ticket
- Extensions locked to physical boxes
- Extensions and call flows rebuilt in the cloud
- Numbers ported carrier-to-carrier with zero downtime
- Voicemail boxes, ring groups, and paging zones migrated
- Old PBX decommissioned only when you're satisfied
Discovery
We document every extension, ring group, and call flow on your on-prem PBX.
Parallel cutover
Old and new systems run side-by-side for a week with call forwarding as the bridge.
Port & retire
Numbers port carrier-to-carrier. Once you're happy, the on-prem hardware is decommissioned.
A new hire takes one form. Offboarding is just as fast.
Adding a new hire in Teloz is a single form: name, extension, department, role. Their softphone, voicemail, and direct number provision automatically. Offboarding revokes access, forwards voicemail to a manager, and releases the number back to the pool.
Instant onboarding
Fill one form — softphone, voicemail, and DID provision automatically.
SSO with your IdP
Okta, Azure AD, and Google Workspace are standard. SCIM for automatic provisioning.
Full audit log
Every admin action writes to an immutable log — who changed what, when, and why.
US businesses run their phones on Teloz.
From single offices to multi-site operations, Teloz keeps every extension ringing.

“Eleven branches, one dial plan, four-digit extensions across the country. Setup took an afternoon.”
“We kept our Yealink deskphones and added softphones for the road. The carrier bill dropped 47% month one.”
