Key Takeaways (TL;DR)
- What it is: An Aircall migration moves business calling from a legacy platform to cloud calling, with a deliberate plan for numbers, routing, devices, CRM records, and support.
- Why it matters: The change can reduce administrative friction and make calling data usable in customer workflows instead of leaving it in a separate phone system.
- Porting priority: Start the number-porting process early, keep the current carrier active, and prepare a fallback plan for critical lines.
- CRM decision: Define what call activity should create, update, or display in Salesforce, HubSpot, or another CRM before enabling the integration broadly.
- Bottom line: The strongest migrations treat Aircall as a business-process and adoption project, not only a telephony replacement.
A legacy phone system may still carry calls reliably, but reliability alone is not enough. Teams need calling to follow the customer record, support distributed work, and adapt when responsibilities change. This cross-industry playbook covers how to move to Aircall without treating porting, network readiness, CRM design, and user adoption as afterthoughts.
Why Replace a Legacy Phone System?
Organizations replace legacy calling because their operating model has changed. Older systems can make administration slow, keep call context separate from CRM data, and complicate distributed work. The goal is a more consistent path from conversation to action.
| Legacy-system constraint | What to evaluate with Aircall |
|---|---|
| Ongoing administration and unpredictable operating burden | How easily admins can add users, change routing, manage numbers, and see call activity without a specialist queue. |
| Limited features or visibility | Whether queues, IVR, analytics, recordings, and collaboration settings support the actual customer journey. |
| Calling data outside the CRM | How caller context, activity logging, dispositions, and follow-up work should appear in the system of record. |
| Difficulty scaling teams or locations | How roles, business hours, routing, and devices can be adjusted as the organization changes. |
Before selecting settings, document the business outcome behind the move: fewer missed calls, faster follow-up, consistent routing, clearer supervisor oversight, or a better connection between calling and CRM work. That outcome becomes the test for each design decision.
Plan the Migration Before You Configure
Start with discovery. Inventory every number, queue, IVR menu, voicemail, business-hours rule, integration, device, and user group. Flag publicly published and business-critical numbers, then map the current caller journey and its failure points.
Assign an executive sponsor, a business owner for routing, IT for network and device readiness, CRM owners for data behavior, and frontline champions for training. Aircall’s admin and supervisor getting-started guide organizes onboarding around numbers, teams, users, integrations, and analytics. Give each workstream an accountable owner and acceptance criteria.
Build a timeline around dependencies, not a single launch date. Include a pilot, tests for inbound and outbound scenarios, a routing-rule change freeze, and a staffed support window after launch.
Port Numbers Early and Keep a Fallback Plan
Number porting transfers an existing number from the current provider to Aircall. It is often the highest-risk migration step because a carrier controls the final date and can reject mismatched details or documents. Aircall’s official porting guide advises verifying availability, required documents, and country-specific timing before submission.
- Create a number inventory. Record every number, its current carrier, account holder, service address, billing details, usage, associated routing, and business criticality.
- Validate ownership details. Reconcile the information against the current carrier’s records before submitting documents. Small mismatches can cause a rejection or delay.
- Sequence the request. Start with the most complex or business-critical porting dependencies, but consider a lower-risk pilot number if the organization needs to validate its internal process first.
- Keep the current service active. Do not cancel the losing carrier before the port completes. Maintain existing routing and voicemail until you have confirmed the number is working in Aircall.
- Plan the cutover. Assign an owner to test inbound calls, outbound caller ID, transfer behavior, queues, voicemails, and CRM logging immediately after the number moves.
Use a written contingency plan for each critical number. It should name the business owner, the test callers, an alternate contact route, the escalation path, and the exact condition for communicating a delay. A backup number, temporary forwarding path, or prominently staffed alternative channel can protect customer access while the team resolves a porting issue. Make that plan visible to service, sales, operations, and leadership before cutover.
Set Up the Network, Devices, and Calling Environment
Cloud calling depends on the quality and stability of the network at each work location. Ask IT to test office, home, and mobile working conditions before launch, rather than troubleshooting call quality only after users are live. Aircall’s network requirements and recommendations state a minimum of 100 Kbps upstream and downstream for each concurrent call and a rough planning estimate of 1 Mbps per person, in addition to the bandwidth required by other applications. IT should also review firewall allowlisting, Quality of Service, Wi-Fi coverage, VPN behavior, and a backup connection for critical users.
| Option | Best fit | Migration consideration |
|---|---|---|
| Aircall Workspace softphone | Teams that work across laptops, home offices, shared spaces, or multiple locations. | Standardize headsets, browser or app permissions, sign-in steps, and a quick troubleshooting path. |
| Desk-phone workflow | Roles that need a fixed physical endpoint or are accustomed to a shared reception-style environment. | Confirm device compatibility, physical placement, power, network connection, and user coaching before cutover. |
| Mixed model | Organizations with varied roles and work environments. | Document which device is primary for each role so call handling and support expectations stay clear. |
Run a structured test script with representative users. Test numbers, inbound and outbound calls, transfers, queues, voicemail, headsets, caller ID, remote access, and degraded-network behavior. Treat each failed test as a design input, not a training workaround.
Design CRM Integration Before You Turn It On
A phone migration creates value when call context reaches the people and records that need it. Start by deciding which data matters: caller match, call direction, outcome, duration, recording access, voicemail, tags, notes, owner, follow-up task, and reporting fields. Then decide where each element belongs and which system is authoritative. This is especially important when a call could relate to more than one contact, company, deal, ticket, or case.
For Salesforce, Aircall describes its integration as enabling calls within Salesforce and supporting the logging of call details. Configure it against the organization’s record model, not a generic default. Pair the rollout with a review of Salesforce implementation and advisory priorities so dispositions, tasks, permissions, and reports reflect the workflow users actually follow.
For HubSpot, Aircall’s official integration overview highlights bringing call information into HubSpot and displaying caller information before a call begins. Test how call activity should be associated with contacts, companies, deals, and tickets. Teams that need to align calling with lifecycle data and service work should also review their HubSpot CRM strategy and optimization.
For another CRM or a custom stack, validate the integration method, authorization model, field mapping, error handling, reporting behavior, and retention rules before rollout. A robust calling-to-CRM design is an integration project, not merely an app installation. Vantage Point’s system integration and data migration services can help define the data flow and test the handoffs.
Train for Adoption, Not Just Feature Awareness
People need to know more than where the dial pad moved. Create role-based practice for agents, managers, administrators, and CRM owners. Agents should practice answering, transferring, tagging, using dispositions, finding call context, and recovering from common connection issues. Managers should practice queue oversight, coaching workflows, and escalation. Administrators need a runbook for users, numbers, routing, permissions, and changes.
Use champions from each team to run realistic scenarios before launch. Keep a short, searchable job aid beside the normal workflow and gather feedback during the first days of use. Connect the change plan to advisory and change-management practices so training, communications, and support reinforce the new operating model.
Go Live in a Controlled Way, Then Optimize
Choose a launch window with enough support coverage to test critical scenarios and respond quickly. Use a command center with named owners for telephony, network, CRM, and user support. Watch successful connection rates, abandoned or missed calls, queue behavior, CRM logging exceptions, user-reported issues, and the volume of temporary workarounds. Record every issue with an owner and resolution date.
After the first week, compare the live experience with the baseline. Remove routing rules that no longer fit, refine IVR language, correct CRM mappings, and update training. Ongoing optimization is often where the migration becomes a durable operational improvement rather than a one-time technical event.
Common Migration Pitfalls and How to Avoid Them
| Pitfall | How to avoid it |
|---|---|
| Submitting a port request with mismatched carrier details | Reconcile the current carrier record, documents, and number inventory before the request is sent. |
| Cancelling the old service too early | Keep the losing carrier active until the number has ported and inbound, outbound, and routing tests pass. |
| Configuring CRM logging without business rules | Document record association, required fields, ownership, permissions, and exception handling first. |
| Launching before remote-network testing | Test representative locations, firewalls, Wi-Fi, VPNs, headsets, and backup connectivity before training. |
| Training only one power user | Train by role, publish job aids, name team champions, and staff a launch support channel. |
When Should You Expect Payback?
There is no responsible universal payback date for an Aircall migration. The timing depends on the current operating burden, number of users, network changes, adoption quality, and whether the CRM integration removes real work rather than adding another screen. Do not promise a return before the workflow is stable.
Instead, establish a baseline before launch and review it in stages. In the first 30 days, measure cutover stability, call handling, user confidence, and integration accuracy. From days 31 to 60, look for fewer manual handoffs, cleaner CRM activity, and routing changes that improve the caller experience. From days 61 to 90, compare the fully adopted workflow with the original baseline and decide which improvements are durable. This creates an organization-specific case for payback without relying on vendor averages or unsupported ROI claims.

Frequently Asked Questions
How long does it take to port numbers to Aircall?
Number-porting timing varies by country, carrier, number type, document completeness, and whether the losing carrier accepts the request without changes. Confirm the country-specific requirements with Aircall, submit accurate information early, and do not schedule go-live solely around an assumed port date.
Can we keep our existing business phone numbers when moving to Aircall?
Yes, eligible existing business numbers can generally be moved through a porting process, subject to carrier and country requirements. Verify availability and documents first, keep the current service active, and test every critical number after the transfer.
Should we use softphones or desk phones with Aircall?
Choose the device model based on the role, work setting, and support needs. Softphones are often practical for flexible or distributed teams, while a desk-phone workflow may suit fixed or shared locations; a mixed approach can work when it is documented and supported.
How should Aircall integrate with Salesforce or HubSpot?
Aircall integration should be designed around the CRM records, fields, permissions, and reports that support the customer workflow. Test caller matching, activity association, outcome capture, and exception handling before rollout so the integration improves data quality instead of creating duplicate or incomplete activity.
What should we test before an Aircall go-live?
Test inbound and outbound calls, caller ID, transfers, queues, voicemail, CRM logging, headsets, user permissions, remote networks, and escalation procedures. Include real users and representative customer scenarios so the team can correct issues before a business-critical caller encounters them.
