Create Automated Dialer + 3CX Integrated IVR

Project: Auto Dialer with IVR + 3CX Integration

I need a simple automated dialing system with the following features:

Core Requirements:
• Use a SIP trunk with a static caller ID (I will provide SIP details)
• Upload and dial multiple phone numbers (CSV or manual input)
• Automatically call numbers (sequential or limited parallel dialing)

IVR Function:
• When a call is answered, play a recorded message
• The recipient can press 1 to be transferred to a live agent
• Detect DTMF input reliably

3CX Integration:
• System must connect to 3CX
• When user presses 1, transfer the call to:
• A queue, ring group, or extension in 3CX
• Agents will answer calls via 3CX

Admin Panel (Very Simple UI):
• Upload/manage phone numbers
• Start / pause / stop campaigns
• Upload IVR audio
• Basic live call status (ringing, answered, transferred)
• Call logs/reporting

Suggested Tech (open to alternatives):
• Asterisk or similar for call handling
• Web-based dashboard (simple and easy to use)

Other Notes:
• Must support call transfer (SIP REFER or similar)
• Limit concurrent calls to avoid overload
• Clean, stable, and easy to operate system
