Three powerful modes, one platform

Every SIP user can switch between modes depending on their workflow — no extra setup required.

Mode 1

Manual Dialer

Classic browser-based SIP dialer. Type a number, hit call. Full DTMF support for IVR navigation and keyboard shortcuts for speed.

  • Dial any number from browser — no app needed
  • Physical keyboard support for fast dialing
  • DTMF tones during call (navigate IVR menus)
  • Captures called party's keypresses in real time — saved to DTMF history log
  • Crystal clear WebRTC audio
  • Incoming calls with accept/reject
🎤 Mode 2

Auto-Dialer — Agent

Upload a CSV list of numbers and let the system dial them one by one automatically. When someone answers, you talk. When you hang up, the next call starts after a configurable delay.

  • Upload CSV — one number per line
  • Auto-dials next number after each call ends
  • Configurable wait time between calls (default 10s)
  • Real-time progress tracker with answered/busy stats
  • Called party's DTMF keypresses shown live on dialer screen and saved per number
  • Pause, resume, or stop at any time
🔊 Mode 3

Auto-Dialer — IVR

Fully automated. Upload your number list and an audio recording. The system calls each number server-side, plays your message when answered, and moves to the next — even with your browser closed.

  • Upload MP3 or WAV recording
  • Runs entirely on the server — no browser needed
  • Works 24/7 without user interaction
  • Captures DTMF keypresses from called party — logged per number in campaign dashboard
  • Tracks answered / busy / no-answer per number
  • Pause, resume, or stop remotely from dashboard
🔁 Mode 4

IVR + Live Transfer

Combines automation with human touch. Plays your recorded message automatically — if the customer is interested and presses your chosen key, the call instantly transfers to your live agent.

  • Plays IVR recording automatically (server-side)
  • Customer presses your chosen key (1–9) to connect
  • IVR stops instantly, call transfers to your dialer
  • Your browser dialer rings — pick up and talk
  • No interested? Call ends automatically

Up and running in minutes

Connect your existing SIP server — no reconfiguration needed on your users' end.

01

You provide your SIP server

Works with any Asterisk, Magnus Billing, FreePBX, or compatible PBX system. We run a one-command setup script.

02

We configure your tenant

Your company gets an isolated account. SIP users are imported automatically from your Magnus server.

03

Agents open the browser

No app, no plugin. Agents log in with their SIP credentials, choose a mode, and start calling immediately.

04

Calls bridge through Janus

Our Janus WebRTC Gateway bridges browser audio to your SIP server in real time. Your SIP infrastructure stays completely hidden.

Everything your call center needs

A complete outbound calling platform with enterprise-grade features, ready out of the box.

🌐

Works in Any Browser

Fully compatible with Chrome, Firefox, Edge, and Safari. No extensions or plugins — just open a URL and call.

📝

Campaign Manager

Create unlimited campaigns per user. Upload CSV lists, set your delay between calls, track progress in real time, and pause or stop at any moment.

🔊

Server-Side IVR Engine

IVR campaigns run directly on the server — no browser or agent required. Upload any MP3 or WAV file and let it run 24/7 unattended.

Manager Self-Service Portal

Each company has a manager who can add, remove, enable, or disable SIP users independently — no support ticket needed.

🛡

SIP Server Fully Hidden

Users never see your SIP domain or server IP. All traffic proxied through our WebRTC gateway — your infrastructure stays private.

🏢

Multi-Tenant Architecture

Every company runs in complete isolation. Separate users, SIP servers, campaigns, and manager access. Unlimited users per tenant.

🔁

Smart IVR-to-Agent Transfer

IVR campaigns that convert. When a customer presses your chosen key, the recording stops instantly and the call transfers live to your browser dialer — no separate hardware needed.

📊

Call Result Tracking

Every campaign number is tracked as Answered, Busy, No Answer, Transferred, or Failed. View progress and stats live as the campaign runs.

One-Command Setup

Paste one command into your Magnus/Asterisk server — it configures everything automatically. No manual SIP configuration needed.

🔢

Remote DTMF Capture

Capture keypresses entered by the called party — across all modes. IVR campaigns log digits server-side via RFC 2833. Manual and Agent calls capture them live via Janus WebRTC events and display them on the dialer screen in real time. All logs are viewable per call and auto-purged every 4 hours.

📞

Live Calls Monitor

Admins see every active call across all tenants in real time — SIP user, number, mode, and live duration. Managers see their own agents. The dashboard counter updates every 10 seconds automatically.

📋

Call Notes

After every call, agents are prompted to write a quick note and optionally schedule a callback. Notes are stored per phone number and can be reviewed anytime. IVR campaign notes are managed from the campaign dashboard.

🚫

Blacklist / DNC

Build a Do-Not-Call list per tenant. Numbers on the blacklist are automatically filtered out when a campaign CSV is uploaded — they never get dialed. Manage the list manually from the campaign page at any time.

📅

Callback Scheduler

Schedule a follow-up call for any number directly from the post-call screen. A badge on the dialer shows pending callbacks at a glance. Mark callbacks as done to keep the list clean.

Work Hours & Call Limits

Admins can set allowed calling hours and a daily call limit per tenant. Managers can set individual daily limits per SIP user. When a limit is reached the campaign pauses automatically and the agent is notified.

🔗

Webhook Integration

Configure a webhook URL and receive a POST request after every call. The payload includes phone number, duration, result, call mode, DTMF digits pressed, and the agent's note — ready to pipe into n8n, Zapier, or any CRM.

📊

CDR Reports

Full call detail records for every level. Admins see all tenants with company name. Managers filter by SIP user. Agents see only their own calls. Filter by date range and status. Export to CSV in one click.

🎙

IVR Maker

Create professional IVR announcements instantly. Type your script, choose an AI voice (6 OpenAI voices), preview it live, and download as MP3 — ready to use in your IVR campaigns without leaving the platform.

Your SIP server stays invisible

Unlike traditional softphones, CellHub Dialer never exposes your SIP infrastructure to end users.

  • SIP server IP and domain never reach the user's browser — all traffic proxied through Janus.
  • Protects your PBX from direct internet exposure, significantly reducing attack surface.
  • Users cannot reverse-engineer your SIP infrastructure from browser dev tools or network logs.
  • TURN relay ensures WebRTC works even behind strict firewalls and NAT.
  • Each tenant is fully isolated — one company cannot access another company's data.
  • Session-based auth: credentials never stored in URLs, cookies, or local storage.
