From On-Premise to the Cloud: How to Transition Your PBX with Minimal Risk
Many Canadian businesses still operate with on-premise PBX systems—reliable, familiar, but increasingly inflexible in today’s digital-first world. As remote work becomes permanent and customer expectations rise, the shift to the cloud is no longer a “nice-to-have”—it’s essential.
But change brings concern: What happens to our call flow? What if we lose service during migration? Is our team ready?
That’s where Iristel comes in—to make the transition smooth, secure, and stress-free.

Why Move to the Cloud?
Here’s what you gain by migrating your phone system to Iristel’s cloud communications platform:
- Scalability – Instantly add or remove users as your business grows
- Business Continuity – Cloud redundancy means fewer outages and faster recovery
- Remote Enablement – Your team stays connected from anywhere
- Lower Total Cost of Ownership – No need to maintain aging hardware
- Built-in Features – Auto-attendants, voicemail-to-email, mobile apps, call analytics, and more
5 Steps to a Low-Risk PBX Migration with Iristel
1. Audit Your Current Setup
We help you assess your existing PBX hardware, call flows, extensions, and carrier services. This ensures we replicate what works—while modernizing what doesn’t.
2. Create a Migration Plan
Our team maps out a phased migration plan with rollback options. Whether it’s all at once or location by location, we adapt to your pace.
3. Port Your Numbers Safely
We coordinate the number porting process to avoid downtime. You keep your numbers, and we ensure calls route correctly from day one.
4. Hybrid Options Available
Not ready to retire your PBX just yet? No problem. We can integrate your on-premise system with SIP trunks while you prepare for full migration later.
5. Onboarding & Training
Your team gets full onboarding, from how to use the softphone app to managing voicemail and auto-attendants. We also provide recorded or live training if needed.


What About Risks?
Here’s how Iristel mitigates common concerns:

- Centralized call handling across provinces
And not a single call was dropped during migration.
