AMAI Voice
AMAI Voice is an AI-first platform that combines voice agents with artificial intelligence, proprietary telephony (FreeSWITCH + SIP Trunk), and a management dashboard in one solution.

When to choose AMAI Voice?
AMAI Voice is the best option if you identify with any of these scenarios.
You want AI agents to handle calls
You're not looking for a PBX with classic IVR, but for voice agents with artificial intelligence that can hold natural conversations, answer questions, schedule appointments, and resolve inquiries autonomously.
You want to automate customer service
Your human agents spend hours on repetitive calls. An AMAI Voice agent can handle 80% of incoming calls automatically, freeing your team for higher-value tasks.
You are a distributor and want to resell
AMAI Voice offers white-label and multitenant management for distributors. You can offer AI voice agents under your own brand to your clients, something Fonvirtual does not allow.
You prefer to pay for usage, with no commitment
AMAI Voice uses a pay-per-use model without long-term contracts. You only pay for the minutes consumed by your AI agents, with no fixed monthly fees per user.
When to choose Fonvirtual?
Let's be fair: Fonvirtual is a great option in certain scenarios.
You need ISO certifications and a track record
If your company requires providers with ISO 27001 and ISO 9001 certifications and a proven track record of over 15 years in the Spanish market, Fonvirtual offers that guarantee and stability.
You are looking for a traditional PBX with many features
If you need a classic virtual PBX with extensions, voicemail, call queues, recording, and all the typical PBX features, Fonvirtual has a mature catalog of over 50 proven functionalities.
