Business Phone Systems in Miami

FastPBX is a VoIP business phone system provider based in Miami, Florida. We serve businesses nationwide from our office at 12485 SW 137th Ave Suite 105, Miami, FL 33186, and Miami businesses get a provider that’s right here in South Florida. Our cloud phone systems give small and medium-sized businesses the features of a big company, without a PBX box in the closet or a long-term contract.

Why Miami businesses choose FastPBX

• A Miami-based provider. FastPBX is headquartered in Miami, so you’re working with a local company.
• Local Miami phone numbers. Choose a local number for the areas you serve (305 and 786 cover Miami-Dade), subject to availability, or keep the number you already have.
• Built for hurricane season. Your phone system runs in the cloud, not in your office. If a storm knocks out your power or internet, call continuity forwards calls so your customers still reach you, and the mobile app lets your team answer from anywhere.
• 24/7 U.S.-based support. Talk to a real person, any time.
• No contracts. Try any plan free for 15 days, with a 15-day money-back guarantee.

VoIP features for your Miami business

Every FastPBX plan includes unlimited calling to anywhere in the U.S. and Canada and business text messaging. As you grow, add an auto attendant to greet callers, extension dialing, ring groups and call routing, voicemail to email and call recording. See all features.

Phones and installation

Use desk, cordless and conference phones from Cisco, Polycom and Grandstream (browse hardware), or answer on your computer and cell with no hardware at all. FastPBX phones are plug and play, and we also offer professional installation. See how business phone system installation works.

Local numbers, toll free and virtual numbers

Want a Miami presence without an office here, or a toll free number for customers across Florida and the country? Get a virtual phone number: local, toll free or vanity, ringing wherever your team works.
