Zoom Certified Integrator
Retire your Avaya IP Office or Aura PBX, or move off Avaya Cloud Office, onto Zoom Phone. Numbers ported with zero downtime, extensions, call vectors, hunt groups, auto-attendants and e911 rebuilt natively. One cloud platform for calls, meetings and chat.
Yes, you can migrate from Avaya to Zoom Phone. Codimite, a Zoom Certified Integrator, ports your numbers (LNP) with zero downtime and rebuilds your extensions, Avaya call vectors, hunt groups, auto-attendant trees, voicemail and e911 natively in Zoom Phone, running your existing Avaya system in parallel until each site is validated. The value is the disciplined config rebuild and porting plan, not a risky lift-and-shift off legacy hardware.
Why migrate
On-premise Avaya IP Office / Aura means PBX servers, media gateways, maintenance contracts and end-of-life roadmaps. Zoom Phone is fully cloud, with no boxes to patch or replace.
Avaya's restructuring history leaves many estates on platforms with limited investment ahead. Moving to Zoom Phone removes that risk.
If you already pay for Zoom Meetings or Zoom Team Chat, Zoom Phone lives in the same Zoom Workplace platform, so leaving Avaya removes a separate phone system and vendor.
Calls, meetings, chat and whiteboard under a single admin console, identity provider and security policy, instead of a standalone PBX bolted to your Zoom stack.
Call summaries, voicemail transcription and next-step prompts from the same AI assistant that summarizes your meetings and chats.
What we migrate
| Avaya element | Rebuilt in Zoom Phone | Notes |
|---|---|---|
| DIDs & main numbers | Ported via LNP | Carrier / SIP-trunk 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 vectors & hunt groups | Zoom Phone call queues | Routing, overflow and members reconstructed |
| Voicemail & greetings | Zoom voicemail | Greetings re-recorded/re-uploaded; boxes provisioned |
| e911 / emergency addresses | Dispatchable locations | Registered and tested per site |
| Avaya handsets / SIP devices | Zoom-certified devices | Proprietary Avaya phones swapped; certified SIP re-homed where viable |
| SIP trunks / PRI | Zoom Phone numbers / BYOC | Carrier services migrated or replaced |
| Users & identities | Zoom users | Mapped to your IdP / SSO |
Device strategy, trunking and carrier port timelines are the main schedule drivers, confirmed during the assessment.
Our process
We audit your Avaya platform (IP Office, Aura or Cloud Office), numbers, extensions, vector/hunt-group logic, devices, SIP trunks and e911 footprint, and confirm what ports and what gets rebuilt.
We map your dial plan, routing and locations to Zoom Phone, plan device swaps, and prepare the LNP porting paperwork with your carrier.
Zoom Phone is provisioned alongside Avaya (extensions, IVR, queues, voicemail and e911) so both systems 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. Avaya is decommissioned only after validation.
We test every route and e911 path, then provide adoption support and 24/7 cover through the cutover.

24/7 support & clear reporting. Route-by-route validation and progress visibility through every wave.
FAQs
Yes, on-premise Avaya (IP Office, Aura Communication Manager) and Avaya Cloud Office. We document your dial plan, port numbers via LNP and rebuild extensions, IVR and hunt groups natively in Zoom Phone.
Avaya-proprietary handsets generally do not register to Zoom Phone, so we plan device strategy up front: Zoom-certified SIP handsets are provisioned, and reuse is confirmed where viable during assessment.
No. Zoom Phone runs in parallel with Avaya 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 single site; four to ten weeks for multi-site Avaya estates, driven by carrier port timelines (often 7 to 15 business days), device swaps and IVR/hunt-group rebuild.
They are rebuilt natively in Zoom Phone from documented Avaya logic, then validated path-by-path before cutover, cleaner than a lossy lift-and-shift.
