Legacy PBX Discovery
Before anything is disconnected, Nerdi documents the complete telephone environment and identifies services that may not be obvious on a carrier bill.
Legacy PBX Migration + RingCentral

Move from Legacy PBX
to Cloud VoIP.
Nerdi plans and manages the complete transition to RingCentral—from discovering every number and analog dependency to porting, cutover, training, and ongoing local support.
What this solves
A Complete Path from
A Complete Path from
Legacy PBX to RingCentral
The phones are only one part of the project. Nerdi inventories the old environment, designs the new call experience, coordinates the port, and supports your team through launch.
RingCentral Cloud Phone System
Nerdi designs and deploys a RingCentral system that supports office, remote, and mobile employees without maintaining an aging on-premises PBX.
Number Porting & Managed Cutover
Your established phone numbers are business assets. Nerdi coordinates porting, testing, timing, and fallback planning to reduce disruption during the transition.
Managed migration
A controlled path from PBX to cloud.
We sequence the work so the new environment is configured and tested before the established numbers move.
- 01
Discover
Inventory numbers, users, devices, carriers, call flows, and hidden analog dependencies.
- 02
Design
Build the RingCentral tenant, licensing plan, call routes, devices, and continuity options.
- 03
Prepare
Validate the network, submit port requests, stage phones, test workflows, and train users.
- 04
Cut over
Coordinate the port, verify inbound and outbound calling, and resolve exceptions in real time.
- 05
Support
Tune call flows, document the environment, retire appropriate PBX services, and support the team.
PBX Migration & VoIP Services
Built around the way your business actually works.
Clear coverage, practical implementation, and an accountable partner who can support the service after it is deployed.
Legacy PBX Discovery
Before anything is disconnected, Nerdi documents the complete telephone environment and identifies services that may not be obvious on a carrier bill.
- Direct numbers, extensions, hunt groups, and call paths
- Fax, security, elevator, modem, and specialty lines
- Desk phones, conference rooms, paging, and door access
- Carrier contracts, billing records, and porting requirements
RingCentral Cloud Phone System
Nerdi designs and deploys a RingCentral system that supports office, remote, and mobile employees without maintaining an aging on-premises PBX.
- RingCentral licensing and configuration
- Compatible desk and conference phone provisioning
- Desktop and mobile calling applications
- Multi-location standards and administration
Number Porting & Managed Cutover
Your established phone numbers are business assets. Nerdi coordinates porting, testing, timing, and fallback planning to reduce disruption during the transition.
- Local, toll-free, and fax number inventory
- Porting documentation and carrier coordination
- Staged testing before the live cutover
- Cutover-day validation and issue ownership
Call Flows, Queues & Voicemail
We translate the way calls work today into a cleaner cloud design—or help improve it while preserving the customer experience that matters.
- Auto attendants and multi-level menus
- Business-hours, holiday, and after-hours routing
- Ring groups, queues, voicemail, and escalation
- Emergency, outage, and failover routing options
Fax, POTS & Analog-Line Planning
Not every line should be treated like a normal voice extension. Nerdi identifies analog dependencies and recommends the right migration, replacement, or retention path.
- eFax and cloud fax replacement planning
- Security and fire alarm coordination
- Elevator and emergency line review
- Modem, postage, paging, and specialty-device discovery
Training & Ongoing Support
A successful cutover includes the people using the system. Nerdi prepares users, supports launch day, and remains available for changes after the phones go live.
- Administrator and end-user training
- Quick-reference guides and device orientation
- Post-cutover call-flow adjustments
- Local support and vendor coordination

Questions about VoIP & Legacy PBX Migration
Clear answers before you commit.
Good IT decisions start with understanding scope, responsibility, timing, and what happens after the project.
What is VoIP and how is it different from a traditional phone system?
VoIP (Voice over Internet Protocol) carries calls through an internet-connected platform instead of relying on a traditional on-premises PBX. A cloud system can simplify administration, support office and mobile users, and provide more flexible call routing and continuity options.
Can we keep our existing phone numbers?
In most cases, yes. Nerdi inventories the numbers, validates ownership and carrier requirements, submits the port request, and coordinates the cutover. Final portability and timing are determined by the current and receiving carriers.
Can employees use VoIP on their cell phones?
Yes. We provision mobile softphone apps for iOS and Android that let employees make and receive calls using their business phone number — whether they're at home, traveling, or on the road. Personal and business calls stay completely separate.
Does VoIP work during an internet outage?
Where the selected provider and network design support it, failover routing can redirect incoming calls to mobile numbers, another location, or a backup connection during an outage.
What happens to our fax, alarm, elevator, or other analog lines?
Nerdi identifies these lines during discovery and coordinates the appropriate path. Depending on the device, code requirements, carrier support, and vendor guidance, that may involve cloud fax, an analog adapter, a cellular replacement, or retaining a dedicated service.
Do we have to replace every desk phone?
Not always, but existing PBX phones are often proprietary or incompatible with a modern cloud platform. Nerdi reviews current models, recommends compatible RingCentral options, and can also deploy desktop and mobile apps where a physical phone is not needed.
How long does a VoIP deployment take?
Deployment timing depends on user count, number porting, call-flow complexity, hardware, internet readiness, and carrier requirements. Nerdi builds the new environment and confirms a cutover plan before established numbers are moved.
