Dashboard Overview
The FusionGate dashboard provides a real-time view of your gateway status and call activity.
Main Dashboard Elements
| Element | Description |
|---|---|
| Connection Status | Shows SIP registration status (Online/Offline/Registering) |
| SIM Status | Individual status for each SIM slot (Connected/No Signal/Disabled) |
| Active Calls | Current calls in progress with duration and destination |
| Today's Statistics | Call count, total minutes, success rate for the current day |
| System Health | Battery, memory, network quality indicators |
Status Indicators
- Green — Online/Connected/Healthy
- Yellow — Warning/Registering/Low Signal
- Red — Offline/Error/Critical
Call Handling
FusionGate handles the conversion between VoIP (SIP) and GSM calls automatically.
Call Flow
- Incoming SIP Call: Your softswitch routes a VoIP call to FusionGate
- SIM Selection: FusionGate selects an available SIM based on rotation rules
- GSM Call Placed: The device places a native GSM call to the destination
- Audio Bridge: Audio is bridged between SIP and GSM in real-time
- Call Termination: Call ends when either party hangs up
Call Quality Settings
| Codec | G.711 (μ-law/A-law), G.729 supported |
| Echo Cancellation | Enabled by default, adjustable sensitivity |
| Jitter Buffer | Adaptive, 20-200ms range |
| DTMF | RFC 2833 and in-band supported |
Call Limits
Configure limits to protect your SIMs and comply with carrier policies:
- Max Concurrent Calls: Per SIM and total device limits
- Daily Call Limit: Maximum calls per day per SIM
- Call Duration Limit: Maximum length per call
- Cool-down Period: Minimum time between calls on same SIM
SIM Management
Manage your SIM cards for optimal performance and longevity.
SIM Status View
For each SIM slot, you can view:
- Carrier name and network type (3G/4G/5G)
- Signal strength (dBm)
- Today's call count and minutes
- Current status (Active/Resting/Disabled)
- Phone number (if available)
SIM Rotation
FusionGate automatically rotates between SIMs to prevent detection and extend SIM life:
| Rotation Mode | Description |
|---|---|
| Round Robin | Alternate between SIMs for each call |
| Load Balance | Distribute calls evenly based on daily usage |
| Priority | Use primary SIM until limit, then switch to secondary |
| Time-Based | Switch SIMs based on time schedule |
SIM Health Monitoring
FusionGate monitors SIM health and alerts you to issues:
- Low balance detection (for prepaid SIMs)
- Registration failures
- Unusual call failure rates
- Network deregistration
Automation Features
FusionGate includes powerful automation to minimize manual intervention.
Self-Healing
- Auto-Reconnect: Automatically re-registers SIP if connection drops
- SIM Recovery: Handles SIM pop-ups and network issues automatically
- Watchdog: Restarts services if they become unresponsive
- Scheduled Reboot: Optional daily reboot at specified time
Human-Like Behavior
Stealth features to avoid carrier detection:
- Call Pacing: Random delays between calls (configurable range)
- Variable Duration: Avoid patterns in call lengths
- Rest Periods: SIMs rest after configurable number of calls
- Location Simulation: Periodic cell tower changes (if supported)
Scheduled Tasks
Configure automated tasks:
- Daily statistics export
- Automatic log cleanup
- Scheduled service restarts
- Peak/off-peak hour configurations
Monitoring & Reporting
Real-Time Monitoring
Monitor your gateway status from anywhere:
- Push Notifications: Alerts for critical events
- NOC Integration: API endpoints for your monitoring system
- Telemetry: Continuous health data reporting
Call Detail Records (CDR)
Each call is logged with:
| Call ID | Unique identifier |
| Timestamp | Start and end time |
| Source | Caller ID from SIP |
| Destination | Called number |
| Duration | Call length in seconds |
| SIM Used | Which SIM slot was used |
| Status | Answered/Busy/Failed/No Answer |
| Disconnect Reason | SIP code or GSM cause |
Statistics Dashboard
- Hourly/Daily/Weekly/Monthly call volumes
- Success rate trends
- Per-SIM performance metrics

Troubleshooting
Common Issues
❌ SIP Registration Fails
Possible causes:
- Incorrect credentials — verify username and password
- Network issues — check internet connectivity
- Firewall blocking — ensure SIP ports are open
- IP not whitelisted — add device IP to softswitch ACL
Solution: Check Settings → SIP Account, verify all fields, try UDP if TCP fails.
❌ Calls Fail with "No Route"
Possible causes:
- No active SIM available
- All SIMs at daily limit
- Number format incorrect
Solution: Check SIM status, reset daily counters, verify number format settings.
❌ Poor Audio Quality
Possible causes:
- Weak GSM signal
- Network congestion
- Codec mismatch
Solution: Relocate device for better signal, use G.711 codec, adjust jitter buffer.
❌ SIM Shows "No Signal"
Possible causes:
- SIM not properly inserted
- SIM deactivated by carrier
- Airplane mode enabled
- Device in poor coverage area
Solution: Reseat SIM, check with carrier, verify airplane mode is off.
