VERDICT

Should I use Mitel?

Business & hybrid communication solutions - mitel.com

Depends. A fit for mid-market, multi-site orgs with IT/telecom staff, partner budgets, or legacy Mitel hardware. Small teams and security-sensitive buyers should pick RingCentral, GoTo, or Nextiva instead.

  • Anyone wanting transparent self-serve pricing
