User Manual

This manual covers daily operation of the FusionGate console: reading the dashboard, configuring SIP registration, managing SIMs, and interpreting call records. For first-time setup, see the Installation Guide.

Dashboard Overview

The FusionGate dashboard provides a real-time view of your gateway status and call activity.

Main dashboard elements

Status indicators

Throughout the console, colored status pills communicate health at a glance:

• 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

1. Incoming SIP call: your softswitch routes a VoIP call to FusionGate.
2. SIM selection: FusionGate selects an available SIM based on rotation rules.
3. GSM call placed: the device places a native GSM call to the destination.
4. Audio bridge: audio is bridged between SIP and GSM in real time.
5. Call termination: the call ends when either party hangs up.

Call quality settings

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 the same SIM.

SIP Settings

The SIP account connects FusionGate to your softswitch so VoIP calls can be routed to the gateway. Configure these fields under Settings → SIP Account.

Once saved, the Connection Status indicator transitions through Registering to Online when registration succeeds. A Offline state indicates the gateway is not registered.

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 distribute traffic and extend SIM life:

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

FusionGate includes automation to minimize manual intervention.

Self-healing

• Auto-reconnect: automatically re-registers SIP if the 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 a specified time.

Behavior shaping

Pacing controls smooth out traffic patterns:

• Call pacing: randomized delays between calls within a configurable range.
• Variable duration: avoids repeating patterns in call lengths.
• Rest periods: SIMs rest after a configurable number of calls.
• Location simulation: periodic cell-tower changes (where supported).

Scheduled tasks

Configure automated tasks:

• Daily statistics export.
• Automatic log cleanup.
• Scheduled service restarts.
• Peak / off-peak hour configurations.

Monitoring & CDR

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 the following fields:

Statistics dashboard

• Hourly / daily / weekly / monthly call volumes.
• Success-rate trends.
• Per-SIM performance metrics.
• Peak usage times.
• Export to CSV / JSON.

Event logs

Comprehensive logging for troubleshooting:

• SIP signaling messages.
• Registration events.
• Call-state changes.
• System events and errors.
• Automation actions.

Troubleshooting

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 the device IP to the softswitch ACL.

Solution: open Settings → SIP Account, verify all fields, and try UDP if TCP fails.

Calls fail with "No Route"

Possible causes:

• No active SIM available.
• All SIMs at their daily limit.
• Number format incorrect.

Solution: check SIM status, reset daily counters, and verify number-format settings.

Poor audio quality

Possible causes:

• Weak GSM signal.
• Network congestion.
• Codec mismatch.

Solution: relocate the device for better signal, use the G.711 codec, and adjust the jitter buffer.

SIM shows "No Signal"

Possible causes:

• SIM not properly inserted.
• SIM deactivated by carrier.
• Airplane mode enabled.
• Device in a poor coverage area.

Solution: reseat the SIM, check with the carrier, and verify that airplane mode is off.

Collecting logs for support

1. Go to Settings → Diagnostics.
2. Tap Export Debug Logs.
3. Choose the time range (the last 1 hour is recommended).
4. Logs are saved to the Downloads folder.
5. Send the logs to our team via the Contact page.

Best Practices

• Keep devices charged: maintain 50%+ battery or use always-on power.
• Use quality SIMs: postpaid or unlimited prepaid plans work best.
• Monitor regularly: check the dashboard daily for issues.
• Update the app: install FusionGate updates promptly.
• Back up configurations: export settings before major changes.
• Rotate SIMs: replace SIMs showing high failure rates.
