Quick answer: A typical small to mid-size Hosted PBX migration takes about 5 to 10 business days, depending on number porting, system configuration, carrier requirements and the complexity of your business. That covers transferring your existing numbers, configuring the new system and training staff (Intratel). Larger migrations with multiple locations or complex integrations can take longer. Much of the new system can be configured while your existing service remains active, which helps reduce the risk of disruption during the transition.
How Long Does Switching Business VoIP Providers Take in Canada?
Why the total timeline is longer than the number transfer
When you switch business VoIP providers, two timelines need to be considered. One is number porting, the carrier-to-carrier transfer of your existing numbers. The other is everything around it: planning call flows, building the new system, testing and getting your team comfortable with it.
A small to mid-size Hosted PBX deployment may take approximately 5 to 10 business days, although the timeline depends on number porting, system configuration and carrier requirements. Simple setups with only a few users can be completed in days, while multi-location projects with complex integrations take a little longer (Intratel).
That is good news for any business that has delayed a move because it pictured weeks of disruption. The deciding factor is rarely the technology. It is how well the move is planned.
How Long Does Business Phone Number Porting Take?
Local number portability and simple versus complex ports
Porting typically completes within several business days, depending on your current carrier and how complex the request.
The Canadian Radio-television and Telecommunications Commission (CRTC) sets a two-business-day interval for transfers involving wireline carriers. That interval applies to the carrier transfer, not the complete Hosted PBX migration, which also involves account checks, system configuration and testing. Ask your new provider to confirm the expected porting schedule.
Location also matters. If you are moving to a different province or local calling area, you may not be able to keep the number. Check this early if you are relocating or opening a new office at the same time as switching.
| Port type | Typical example | What affects timing | What to prepare |
| Simple port | A few business lines on one account at one location | How quickly the current carrier accepts the request | Recent invoice and exact account details |
| Larger port | Many numbers, several accounts or several locations | More records to match and more coordination between carriers | Full number inventory for every location |
| Partial port | Some numbers move while others stay with the current carrier | Keeping the remaining services intact | A clear list of the numbers that stay behind |
What Are the Steps Involved in Switching VoIP Providers?
A Hosted PBX migration from inventory to cutover
A typical Hosted PBX migration moves through four stages: inventory, port request, parallel setup and cutover. Some of them overlap, which is what keeps the overall timeline short.
Stage 1: Inventory. List every number you use, including main lines, direct lines and fax lines, along with each location, how calls should flow, and whether staff will use desk phones, softphones or both. Hardware is not always required, since softphones and the mobile app can replace desk phones.
Stage 2: The port request. Your new provider needs your account details and a signed porting request form. Carriers typically ask for the business name, the service address where the numbers ring, the account holder’s name, the billing telephone number and the account number.
Stage 3: Parallel setup. While the port request is processed, your Hosted PBX is built and tested. Extensions, auto attendant greetings, dial-pad menus and voicemail-to-email with transcription are configured while your current service keeps running.
Stage 4: Cutover. On the confirmed port date, your numbers move across. Calls are tested in both directions, and staff get a short orientation so the first day on the new system feels routine.
What Causes Delays When Switching VoIP Providers?
The account details carriers reject most often
Mismatched account details are a common cause of number porting delays. A port request is rejected when the submitted details do not match the current carrier’s records, or when there are pending service orders on the account. A billing telephone number, business name or service address that differs even slightly from what the carrier has on file is enough to send the request back.
Partial ports need extra care, since a clear list of the numbers that remain helps protect the services you are keeping.
The simplest fix is preparation. Before the port is submitted, ask your current carrier for a recent invoice and the exact account details on file, and use them word for word.
Is Your Network Ready for a New Business VoIP Provider?
VoIP bandwidth requirements and call quality checks before cutover
Bandwidth needs depend on the codec, your network setup and how many calls run at once. As a planning guide, allow about 25 Kb/s to 80 Kb/s per call in each direction, depending on the codec, plus extra capacity for network overhead. Once that overhead is counted, Cisco’s tables show about 31.2 Kbps per call for G.729 and 87.2 Kbps for G.711 over Ethernet.
Quality of Service (QoS) settings help by prioritizing voice traffic over large downloads and backups. Before you switch, check your available bandwidth, how stable your connection is and how many calls you expect to handle at the same time.
Can You Switch VoIP Providers Without Losing Business Calls?
Planning a cutover that minimizes service interruptions
You can greatly reduce the risk of missed calls by keeping your existing service active until porting is complete, with your new Hosted PBX configured and tested before the transfer. Temporary interruptions can still occur at cutover, and coordinating the timing with your provider helps reduce the chance of missed calls.
Keep the old service active until the port is complete. Close the old account only once your numbers are confirmed working on the new system (CRTC).
Schedule the cutover outside your busiest hours. Pick a time when call volume is lowest for your business, and make sure your new provider’s support team is available on the day to test calls and adjust routing.
Check your current commitments before you switch. If your business is partway through a term with its current provider, check how much time is left and whether any charges apply for leaving early. Depending on your existing phone system, a hybrid or phased move may be possible, adding VoIP alongside your current service and moving fully later. Intratel can review your setup and recommend the most practical approach.

💬 Common Questions
Can I keep my business phone number when I switch VoIP providers?
In many cases, yes. Whether a number can move depends on factors such as your current provider and the number’s local calling area, and moving to a different province or local calling area may mean you need a new number. Confirm with Intratel before the transfer is scheduled, especially if your business is relocating.
Should I cancel my old provider before switching?
No. Keep your old service active until the port is complete. Cancelling first can cause the port to be rejected or delayed, and once the old service is cancelled you will need a new number.
Is there a charge to port my numbers to Intratel?
No. Intratel handles number porting at no extra charge.
Can I switch if I am partway through a term with my current provider?
Often, yes. Check how much time is left on your current term and whether any charges apply for leaving early. Depending on your existing system, a hybrid or phased move may be possible, and Intratel can help you assess the options before you switch.
Do I need new phones to switch to a Hosted PBX?
Not always. Softphones and the mobile app can replace desk phones, and some existing desk phones may work with the new system. Check with your provider which of your current phones are compatible.
