If you have an active support agreement with Mitel for your Mitel MiVoice Connect platform, you can access the latest software. Contact our team to discuss your options for upgrading your Connect system.

What is Mitel Connect?

Mitel Connect is the new software release that replaces ShoreTel 14.2. Mitel Connect takes your ShoreTel system to new highs with brand-new software, upgraded switches, modernized phones, improved HQ Director, and a new desktop application designed to increase your productivity and communication.

While Mitel Connect introduces new telephones, switches, and applications, most of the ShoreTel telephone models and switches remain fully compatible with the latest software, meaning that customers may not need to upgrade phones or switches. Below you will see the list of telephones and switches that are not compatible with Mitel Connect:

  • Switches: SG-40, SG-60, SG-120/24, and SG-T1 (Not T1k)

  • Telephones: IP100, IP210, and IP560

No need to worry. If you have any of the devices listed above as part of your phone system, our consultants will work with you to find the most effective way to replace these devices as you migrate to Mitel Connect.

How to start the upgrade process?

The planning process for the upgrade can take a few weeks, depending on the size of the system. We suggest you schedule a meeting with your Account Manager to schedule a No-Cost system review and discuss a plan that fits your needs when upgrading your Mitel Connect system.

What if you don’t want to migrate to Mitel Connect?

For companies that currently have an In-House phone system but are looking to simplify their communications, moving your communications to the cloud is the smartest choice. Contact one of our consultants to discuss options available if you are considering moving your communications to the Cloud.
