As a long-standing Mitel Platinum Partner, CTPros has supported Mitel and ShoreTel environments for decades — and is now one of the most experienced partners in the country to help clients navigate the platform's end-of-life timeline and plan the right path forward.
Mitel has filed for Chapter 11 bankruptcy. MiVoice Connect has reached End-of-Sale, and a full End-of-Life timeline is now published — licensing support ends December 2025, full platform EoL arrives December 2029. That timeline is real, and it means every organization still running a Mitel or ShoreTel system needs a plan.
CTPros has been in this with clients from the beginning. The depth of experience CTPros has with these systems — and with the migration paths away from them — is exactly what organizations need right now. The goal isn't to alarm anyone. It's to make sure clients understand their options and move on their own timeline with an experienced partner beside them.
CTPros starts every Mitel and ShoreTel engagement with a full PBX audit — assessing the current hardware and software environment, identifying deficiencies, documenting what's in place, and building a clear picture of what the migration needs to account for. The audit is the foundation of a well-planned transition. It's also the starting point for clients who aren't sure where they stand.
For organizations that need to stay on Mitel or ShoreTel through part or all of the EoL window, CTPros continues to support existing environments — maintaining system performance, resolving issues, and keeping the platform operational while the client plans and executes their transition.
CTPros has guided clients through Mitel and ShoreTel migrations to every major cloud platform. The migration process starts with the PBX audit, moves through platform evaluation and selection, and covers porting, configuration, integration rebuilds, and a structured cutover that protects continuity throughout. CTPros owns the full migration — not just the destination platform.
For organizations currently working with another Mitel or ShoreTel partner who want to switch to CTPros, the Change of Partner process is straightforward. CTPros has facilitated many of these transitions and can walk new clients through the process quickly so the change doesn't create a support gap during the transition.
For clients managing on-premise Mitel systems alongside Microsoft Windows Server environments, CTPros maintains a compatibility reference page — documenting which Microsoft Server updates are safe to install with each Mitel build version. Available in the Legacy Resources section below.
CTPros-produced training videos for ShoreTel and Mitel Connect users — covering platform features, configuration, and common tasks for existing users who need self-service reference material. Available in the Legacy Resources section below.
Organizations still running Mitel or ShoreTel systems have a window to plan and execute a migration — but that window has a defined end. CTPros has the experience to help clients move deliberately rather than reactively, and to make sure the destination platform is the right fit before the migration begins.

For organizations that need to remain on Mitel or ShoreTel through part of the EoL window, CloudCare provides ongoing support — break/fix resolution, adds/moves/changes, vendor escalation management, and 24-hour mission-critical availability — so the system stays operational while the migration is planned and executed.
One of the most common migration destinations for organizations leaving Mitel/ShoreTel. CTPros has guided many Mitel-to-RingCentral migrations and can walk through the process from PBX audit through go-live.
A strong UCaaS option for organizations evaluating their post-Mitel platform. CTPros implements and supports the full Zoom environment for organizations making the transition.
For organizations with contact center operations looking for a CCaaS destination after Mitel, CTPros implements and supports Talkdesk as part of the migration.
The PBX audit is the right first step — it gives CTPros and the client a clear picture of what's in place before any platform recommendation is made. Start there.
