Zoom Certified Integrator
Move your phone system off Nextiva and onto Zoom Phone, with numbers ported with zero downtime, IVR, call queues, extensions and e911 rebuilt natively. One platform for calls, meetings and chat.
Yes, you can migrate from Nextiva to Zoom Phone. Codimite, a Zoom Certified Integrator, ports your numbers (LNP) with zero downtime and rebuilds your extensions, IVR/auto-attendant trees, call queues, voicemail and e911 natively in Zoom Phone, running both systems in parallel until each site is validated. The value is the disciplined config rebuild and porting plan, not a risky lift-and-shift.
Why migrate
If you already pay for Zoom Meetings or Zoom Team Chat, Zoom Phone lives in the same Zoom Workplace platform, so moving off Nextiva removes a separate phone subscription and vendor.
Calls, meetings, chat and whiteboard under a single admin console, identity provider and security policy, instead of running Nextiva alongside your Zoom stack.
Teams that have outgrown a bundled SMB suite get enterprise admin, granular routing and unified policy across the whole Zoom Workplace platform.
Call summaries, voicemail transcription and next-step prompts from the same AI assistant that summarizes your meetings and chats.
Zoom Phone's metered and unlimited plans and global coverage are priced aggressively against incumbent UCaaS contracts.
What we migrate
| Nextiva element | Rebuilt in Zoom Phone | Notes |
|---|---|---|
| DIDs & main numbers | Ported via LNP | Carrier port in a scheduled window; zero downtime |
| Extensions & dial plan | Zoom Phone extensions | Numbering scheme preserved where possible |
| Auto-attendant / IVR | Native auto-attendant trees | Menus and business hours rebuilt and tested |
| Call flows & queues | Zoom Phone call queues | Routing, overflow and agents reconstructed |
| Voicemail & greetings | Zoom voicemail | Greetings re-recorded/re-uploaded; boxes provisioned |
| e911 / emergency addresses | Dispatchable locations | Registered and tested per site |
| SIP / desk phones | Supported devices re-provisioned | Certified handsets re-homed; others swapped |
| CX / CRM workflows | Assessed separately | Mapped to Zoom or your existing CRM |
| Users & identities | Zoom users | Mapped to your IdP / SSO |
Routing complexity, any CX/CRM workflows and carrier port timelines are the main schedule drivers, confirmed during the assessment.
Our process
We audit your Nextiva numbers, extensions, auto-attendant/call-flow logic, devices, any CX/CRM workflows and e911 footprint, and confirm what ports and what gets rebuilt.
We map your dial plan, routing and locations to Zoom Phone and prepare the LNP porting paperwork with your carrier.
Zoom Phone is provisioned alongside Nextiva (extensions, IVR, queues, voicemail and e911) so both run in parallel.
A pilot group validates call quality, routing and devices before any numbers move.
Numbers cut over in scheduled LNP windows with rollback ready; zero downtime per number.
We test every route and e911 path, then provide adoption support and 24/7 cover through the cutover.

FAQs
Yes. We manage local number portability (LNP) for your DIDs and main numbers, including paperwork, carrier coordination and a scheduled port window so calls never drop.
No. Zoom Phone runs in parallel with Nextiva and numbers cut over in a scheduled LNP window, typically minutes per number, so there is no service gap.
One to two weeks for a small business; four to eight weeks for larger or multi-site organisations, driven by carrier port timelines (often 7 to 15 business days) and IVR/queue rebuild.
They are rebuilt natively in Zoom Phone from documented Nextiva logic, then validated path-by-path before cutover.
Those are a separate layer from your phone seats. We migrate the calling to Zoom Phone and assess any CX/CRM workflows separately, mapping them to Zoom or your existing CRM.
