Comcent Review (2026): Voice Infrastructure on Your Own SIP Trunk

Managed voice infrastructure on your own SIP trunk: browser dialers, queues, call recording, AI transcription, and a real-time voice bot — cloud plans or free self-hosted open source

Category: audio · Pricing model: freemium (free self-host) · Official site: comcent.io

What Comcent does

Comcent is a voice-infrastructure platform: browser dialers, call queues, call recording, AI transcription, and a real-time voice bot — either hosted and managed on Comcent Cloud or self-hosted for free on the open-source Community Edition (AGPL-3.0). You bring your own carrier or SIP trunk (Twilio, Telnyx, and others), and Comcent charges no per-minute talk fee on calls — you pay for the infrastructure and for optional AI minutes. Unlimited seats are included in every plan, and self-hosting takes about 30 seconds to install on any Linux box with a public IP (a $12/month VPS is enough).

Who it’s for

Support and sales teams that need phone features (dialer, queues, recordings, transcripts) without building telephony; agencies and SaaS products that embed a phone widget into a CRM; and engineering teams that would rather run the whole stack themselves. It is not a voice-synthesis tool — for generating speech, a TTS platform is the right fit.

Key features

• Browser dialer and embeddable widget (CRM integration)
• Dynamic call-flow charts for visual routing
• Call queues and recording (retention varies by plan)
• AI transcription and “AI Insights” (per-minute, toggle on)
• “Transfer intelligence (live)” for live call transfer logic
• Real-time voice bot
• BYO carrier or SIP trunk; unlimited seats on every plan
• Comcent Cloud (managed) or Community Edition (free, AGPL-3.0)
• Prepaid-wallet billing; USD, with INR via Razorpay in India

How to use Comcent

1. Sign up at comcent.io (cloud) or self-host the Community Edition with its one-command Docker installer.
2. Connect your SIP trunk or carrier.
3. Configure dialers, queues, and call flows.
4. Turn on AI transcription/Insights for the calls you want analyzed.
5. Embed the widget in your app or CRM where needed.

Limitations

• Concurrent-call caps per plan (5/20/50); extra concurrency costs $3–5/month each.
• Recording retention varies by plan (30 days / 1 year / 3 years).
• AI minutes are metered beyond included allotments ($0.012–0.020/min depending on plan).
• Self-hosting is your ops burden (Linux, Docker, ports, TLS).
• Prepaid wallet: payments are non-refundable, and carrier minutes are paid to your own carrier.
