Mitel phone system migration

Keep compatible Mitel phones. Choose a new voice path.

Compare on-premises and cloud business phone systems with a model-by-model plan for your existing Mitel handsets.

Options after Mitel’s financial restructuring

Mitel completed its financial restructuring in June 2025. Your phone system choices still depend on your equipment, requirements and support arrangements.

If you operate a Mitel phone system, we can help you evaluate whether to maintain the current platform, move to an on-premises VoIP system, or host your new voice platform in the cloud. We review licence and support status, phone models, SIP firmware, provisioning, call flows and connectivity before recommending a path. See Mitel’s restructuring update.

Fraser Valley IT Voice can support many existing Mitel SIP handsets, but compatibility is model and firmware dependent. We test a representative handset and required functions such as BLF, paging, voicemail and transfer before committing to a fleet-wide migration.

On-premises or cloud business phone systems

Whether you have a small office or hundreds of handsets across several sites, we can assess your Mitel estate and quote a phased migration. We can work with your current phones where supported and identify only the devices that require replacement. See Fraser Valley Voice features and pricing.

Migration choices

On-premises PBX at your office or data centre
Cloud hosted business phone system
Hybrid or staged phone migration
Reuse of compatible Mitel SIP handsets
New phones where existing models are unsuitable
Mobile, desktop and web calling options
Number porting and call routing changes
Paging, intercom and analog device review

We map extensions, DIDs, auto attendants, queues and business hours, then plan handset provisioning, testing and cutover. Existing equipment can often reduce waste and upfront costs, subject to a compatibility assessment. We also plan for power, network and internet resilience at each site.
