// Managed Voice — Use Case
Cloud Phone System Migration without the downtime
Replace your aging PBX or on-prem system with a fully managed cloud phone platform — numbers ported, call flows rebuilt, and every user cut over without a dropped call.
Legacy phone systems fail silently. They run out of support, accumulate unreliable hardware, and tie your team to a single office. A cloud migration fixes all three — but only if it's done right. InfoNetworks manages the entire transition: carrier coordination, number porting, dial-plan design, and a parallel-run period so you never go dark.
// What We Deliver
Built for a clean cutover
Zero-Downtime Cutover
We run your legacy and cloud systems in parallel during the transition. Staff learn the new platform before the old one is retired. Cutover happens on your schedule — not the carrier's.
Full Number Porting
Every number — mainline, DID, toll-free, and fax — moves with you. We manage LOA submission, porting timelines, and interim call forwarding so nothing falls through the cracks.
Call Flows Rebuilt Better
We don't just replicate your old dial plan — we redesign it. Auto attendants, ring groups, hunt lists, and voicemail-to-email are all reconfigured with modern best practices from day one.
// How It Works
From legacy to cloud in four steps
Every migration starts with a full audit of your current environment — lines, extensions, call flows, analog devices, and carrier contracts. From there we build a migration plan with exact dates, a parallel-run window, and a rollback option. Nothing goes live until you've tested it.
Step 01
Environment Audit
We inventory every line, device, call flow, and carrier contract in your current setup. This catches hidden analog lines, undocumented DIDs, and legacy equipment before they become migration blockers.
Step 02
Platform Selection & Design
We select the cloud platform that fits your size, compliance requirements, and budget — then design the full dial plan, including auto attendants, ring groups, queues, and failover routing before any hardware ships.
Step 03
Parallel Run & Training
Both systems run simultaneously during the transition window. Users are trained on new endpoints — desk phones, softphones, or mobile apps — and all call flows are tested end-to-end before cutover day.
Step 04
Cutover & Ongoing Management
Cutover is scheduled for low-traffic hours. An InfoNetworks engineer is on the line throughout. Post-migration, your system is fully managed — we handle moves, adds, changes, and monitoring going forward.
// Who It's For
Right for you if...
This use case fits businesses running an on-prem PBX (Avaya, Cisco, NEC, Mitel), a hosted system from a carrier that's sunsetting support, or a mix of analog lines and SIP trunks that's become impossible to manage. It's especially valuable for multi-location companies where each office has its own system — and none of them talk to each other cleanly. If your IT team spends more time babysitting the phone system than running the business, a managed cloud migration with InfoNetworks returns that time immediately.
// FAQ
Common questions
Q
Will we lose our phone numbers during the migration?
No. Number porting keeps your existing numbers active throughout the transition. We submit Letter of Authorization paperwork to your current carrier, manage the porting window, and configure interim call forwarding so calls ring on the new system before the port completes. Your customers will never notice a thing.
Q
How long does a typical migration take?
Most small-to-mid-size migrations complete in 30–60 days from kickoff. Larger environments with many analog lines, complex call flows, or compliance requirements may take 60–90 days. The audit phase is the longest — once we have a complete picture, the technical work moves quickly.
Q
What happens if something goes wrong on cutover day?
We maintain rollback capability for 48–72 hours post-cutover. Your legacy system stays available during this window so that if anything unexpected surfaces, we can redirect calls back within minutes. Every migration plan includes an explicit rollback procedure — not as a backup plan, but as a standard deliverable.
