10 Best Mitel Alternatives in 2026

Most businesses are moving away from Mitel due to the upcoming 2026 MiCloud shutdown, high costs, and poor customer support. Its limited integrations, outdated interface, and missing AI features are also pushing teams to seek modern cloud alternatives.

• Micloud Connect shutdown: Mitel is shutting down its MiCloud Connect service, designed for VoIP Calling, by 2026. The closure means that existing customers will lose access to the service, along with technical support and feature updates.
• Price: Many companies find Mitel’s pricing doesn’t match the value, especially as they scale. Users are looking for more affordable cloud options due to their high subscription costs, add-on fees, and maintenance expenses.
• Poor customer service: Users often report slow response times and limited support during outages. The delayed assistance is a major concern for any business.
• Limited integrations: Mitel offers limited integration with modern business tools. Users often face difficulties connecting their phone system with essential apps like CRMs, helpdesks, and collaboration software.
• Lack of advanced features: Mitel phone system lacks stronger analytics, AI support tools, and advanced call management tools like call routing, transfer, and forwarding, that modern businesses need.
• Frequent software issues and complex navigation: Some users report struggling with bugs, outdated UI, and a learning curve that slows onboarding. Users today look for an easy-to-use, feature-rich telephony platform without any errors or issues.
