Open-source call center software, built for your team
Fonemonk gives your team a real agent desktop for live calls, queueing, and presence. Self-host it under AGPLv3, or let us run it for you.
A call center your team actually runs
A real agent desktop
Live call queueing, presence, and a browser softphone for human agents to answer and make calls
Real call analytics
Volume, outcomes, and trends pulled straight from your call history, not a sample chart
Open source, AGPLv3
The full platform is on GitHub. Self-host it on your own infrastructure, or run it hosted with us
See it running on your own call flow
Tell us a bit about your setup and we'll walk you through Fonemonk's agent desktop and call routing live.
Built for real agents, not a demo
Queueing, presence, and a browser softphone your agents use every day. It's open source, so you can see exactly how it works and change it

Engineered for security
Enterprise-grade security measures to protect your call and customer data

Get your team up and running with Fonemonk in just 2 hours
Fully auditable

How Fonemonk stacks up
Self-host for free, or let us run it for $20/seat — either way you bring your own Twilio/Plivo account and pay their real rates. No vendor lock-in, no shared account behind the scenes.

* That's Twilio's/Plivo's own standard per-minute rate, billed directly to your own account — not a Fonemonk fee. Connect your account in Settings → Calling.
Competitor pricing is publicly listed, annual billing where offered, as of August 2026 — compiled from each vendor's pricing page; confirm current rates directly with them before deciding, since SaaS pricing changes often. Dialpad's Contact Center tier is shown (not its cheaper basic phone plan) since it's the closest match to Fonemonk's queueing/agent-desktop feature set.

Don't just take our word for it. See what our customers have to say about their experience.
We self-host Fonemonk on our own infrastructure. The queueing and agent desktop just work, and we're not locked into anyone's roadmap but our own.
Sarah Johnson
Sales Manager, TechCorp
The analytics dashboard provides insights we never had access to before. It's helped us make data-driven decisions that have improved our conversion rates.
Michael Chen
Marketing Director, GrowthLabs
Customer support is exceptional. Any time we've had an issue, the team has been quick to respond and resolve it. Couldn't ask for better service.
Emily Rodriguez
Operations Lead, StartupX
We've tried several similar solutions, but none compare to the ease of use and comprehensive features of Fonemonk. It's been a game-changer for our sales team.
David Kim
CEO, InnovateNow
Being able to read the actual code before we trusted it with customer calls made the security review a non-issue. Try doing that with a closed-source vendor.
Lisa Patel
Sales Director, RemoteFirst
Implementation was seamless, and the ROI was almost immediate. We've increased our sales pipeline by 40% since switching to Fonemonk.
