Switch from Avaya
Replacing your Avaya phone system with 3CX
Many businesses still run Avaya IP Office or older Avaya hardware that's aging out, and they're unsure where the product line is heading. 3CX gives you a modern, software-based phone system that runs in the cloud or on hardware you control, with MIS handling the migration end to end.

Why businesses move
Common frustrations with Avaya
Aging hardware
Proprietary cabinets, cards, and handsets get harder and more expensive to repair every year.
Roadmap uncertainty
Ownership and product changes leave many Avaya customers unsure what support will look like in a few years.
Remote work gaps
Older systems weren't designed for staff who work from home or need full features on their cell phones.
Side by side
Avaya vs. 3CX with MIS
| Avaya | 3CX + MIS | |
|---|---|---|
| Where your system runs | Typically on-site proprietary hardware | Your choice: 3CX-hosted, your own cloud (Azure, AWS, Google Cloud), or on-prem |
| Hardware | Proprietary phones and expansion modules | Open-standard SIP phones from many manufacturers, or no desk phone at all |
| Remote and mobile users | Often requires extra licensing or VPN | Built in with the 3CX apps |
| Who you call for help | Varies by reseller | MIS engineers who know your setup. Real people, no ticket black hole |
| Updates | Major upgrades are often projects | Regular software updates, managed by MIS |
Comparison reflects general platform characteristics. Specific features and terms vary by plan and edition; MIS will confirm details for your situation.

FAQ
Switching questions
Can 3CX run on-site like our Avaya did?
Yes. 3CX can run on a server in your building, in your own cloud account, or hosted by 3CX. MIS will recommend the right fit.
Do we have to replace every phone?
Avaya handsets are generally proprietary, so most will be replaced. Many teams use the 3CX apps for some users and reduce the number of desk phones they need.
