Moving a business phone system from on-premise hardware to the cloud is one of the most impactful infrastructure changes a business can make. Lower costs, better reliability, remote working capability, instant scalability, and automatic updates without maintenance windows. But a phone system migration done badly means calls failing during cutover, numbers not porting correctly, staff unable to make or receive calls, and customers getting a dead line when they ring your business. The stakes are high enough that most businesses put the migration off indefinitely even when they know the current system is costing them too much and holding them back.
Telphi manages cloud migration for business phone systems across the US, UK, and Canada. We plan and execute the complete migration from your existing on-premise PBX, legacy VoIP system, or traditional phone line to a cloud telephony platform. Every number gets ported correctly. Every user gets configured on the new system before cutover. Old and new systems run in parallel during the transition so there is no gap in phone coverage. Most of our migrations complete with zero downtime and zero calls missed on cutover day.
We migrate businesses onto the leading cloud platforms: RingCentral, Nextiva, Dialpad, 8x8, Zoom Phone, Microsoft Teams Phone, and Vonage.
A cloud migration for a business phone system means moving from a phone system that runs on physical hardware in your office or server room to one that runs on servers in a data centre and is accessed over the internet.
Your current phone system is probably one of three things. An on-premise PBX which is a physical box in your office that manages all your calls and requires an engineer to change anything. A legacy hosted VoIP system that was set up years ago and is either no longer supported, has limited features, or costs more than modern alternatives. Or a mix of traditional phone lines and separate systems that have grown together over the years without any coherent architecture.
All three share the same fundamental problems. Hardware that needs maintaining. Engineers needed for any change. Limited remote working capability. No automatic updates. And costs significantly higher than a modern cloud telephony platform.
A cloud phone system solves all of these problems at once. No hardware to maintain, changes happen through a browser, your team works from anywhere, updates happen automatically, and the monthly cost is typically 40% to 60% less than what you are paying now.
The migration from where you are to a cloud phone system is the part that most businesses find daunting. Number porting, system configuration, staff training, cutover planning, and managing the transition without a gap in phone service. Telphi handles all of it. We plan the migration in detail before touching anything, configure the new system completely before cutover day, run the old and new systems in parallel until we are certain everything is working, and execute the cutover at a time that minimises any risk to your business operations.
A complete cloud migration from Telphi covers every step from the initial audit through to go-live and post-migration support. Here is exactly what gets done.
Before any migration work begins, Telphi conducts a full audit of your existing phone system. We document every phone number in use, every extension, every call routing rule, every voicemail configuration, every integration with other systems, and every compliance requirement. This inventory becomes the migration blueprint. Nothing gets missed because it was not documented. The audit also covers your network infrastructure to ensure it can support reliable cloud phone call quality.
Telphi is vendor neutral. We do not resell a single cloud telephony platform. We assess your requirements and recommend the right platform from the full market including RingCentral, Nextiva, Dialpad, 8x8, Zoom Phone, Microsoft Teams Phone, Vonage, and others. The recommendation is based on your call volumes, feature requirements, industry compliance needs, existing technology stack, and budget. You get an honest comparison, not a pitch for whichever platform pays the highest reseller margin.
The new cloud phone system gets fully configured before a single call is migrated to it. Every number, every extension, every call routing rule, every auto attendant script, every voicemail, every integration. Configured and tested in the new environment while the old system continues handling your calls. This parallel configuration approach means cutover day is a switch rather than a build, which is why our migrations complete with zero downtime.
Telphi manages the entire porting process with your current carrier. We handle the porting requests, track the porting timeline, and manage any issues that arise during the process. Your numbers arrive on the new platform on schedule without you having to deal with carrier bureaucracy.
Before any numbers are ported or any cutover happens, we run the old and new systems in parallel. Every routing rule, every voicemail, every integration gets verified with real test calls. Only when everything passes testing do we proceed to the cutover. This approach eliminates the risk of discovering a configuration problem on go-live day when customers are trying to reach you.
Telphi plans the cutover for the lowest-risk time window for your business, typically outside business hours or during a quiet period. We execute the cutover with engineers available to respond immediately to any issue. In most migrations the cutover takes less than 30 minutes and calls start routing through the new system without any interruption.
Every migration includes staff training. Your team gets a walkthrough of the new cloud phone system before cutover day. We provide training documentation and a support contact for the first 30 days post-migration for any questions that come up after the team starts using the system in production.
Every cloud migration follows a structured process. We never rush to cutover and we never cut over until everything is verified. Here is exactly how it works.
We audit your current phone system completely. Every number, extension, routing rule, integration, and compliance requirement gets documented. We assess your network infrastructure and review your current carrier contract terms to confirm porting eligibility and timeline. At the end you receive a full migration report, a platform recommendation with cost comparison, a confirmed number porting timeline, and a detailed migration plan with a go-live date.
Great for:
IT managers and business owners who need a complete picture of the migration before presenting it internally or committing to a cloud platform.
We build and configure the new cloud phone system completely. Every setting from the old system gets replicated on the new one, optimised where appropriate, and documented. We configure integrations with your CRM, Microsoft 365, Google Workspace, or other business tools, and set up call recording and compliance configuration for regulated businesses. You review and sign off the full configuration before we proceed to parallel running.
Great for:
Businesses that want their new cloud phone system configured properly and verified before a single live call touches it.
The new system runs in parallel with the old one. Test calls go through every routing path. Voicemails, transfers, hold music, auto attendant menus, CRM integrations, call recording, and compliance features all get verified with real test calls. We do not proceed to cutover until every test passes.
Great for:
Every business. This step is non-negotiable in every Telphi migration because it is what guarantees a smooth cutover.
We execute the cutover at the agreed time. Numbers port to the new platform. Staff switch to the new system. Telphi engineers are available throughout the cutover window. Post-cutover, we monitor the system for the first 48 hours and provide direct support access for your team for the first 30 days.
Great for:
Businesses that need a smooth, supported go-live with immediate response capability if anything unexpected happens.
The average business moving from an on-premise PBX or legacy hosted system to a modern cloud phone platform cuts their total telecommunications cost by 40% to 60%. No hardware to maintain. No engineer call-out fees. No per-site phone system. No expensive upgrades every few years. The monthly per-user cost covers everything and stays predictable as the business grows.
A cloud phone system is location-independent. A team member at home, in a client meeting, or in a different country accesses the same phone system through the same app. Same number, same extension, same voicemail, same call recording. For businesses that moved to hybrid or remote working, this removes one of the last infrastructure barriers to working from anywhere.
On an on-premise PBX, adding a new user requires ordering hardware, waiting for delivery, and booking an engineer. On a cloud phone system, a new user gets added through the admin portal in five minutes. Adding a new office location takes an afternoon. Changing call routing rules takes two minutes.
Cloud phone platforms update automatically. New features get added without downtime. Security patches get applied without maintenance windows. Your phone system stays current without any effort from your IT team and without any additional cost.
