Prerequisites

Before you begin, make sure you have:

• A FlyNumber account
• At least one active FlyNumber and the phone system enabled
• A valid email address for receiving the activation code

Security Architecture

The phone system app uses WebSocket Secure (WSS) protocol for all communications:

• Provides a secure, encrypted channel for real-time voice and data
• Uses TLS encryption to protect all app traffic
• Ensures enterprise-grade security for communications

Notes

After receiving your activation email:

Outbound Call Format

When making calls, dial in full international format:

• Include country code and full number — a leading + or 00 also works; all three styles connect identically
• Don't dial in national format: drop any leading trunk 0 and add the country code
• Examples:
  • USA/Canada: 19176282411 (country code 1)
  • UK: 442036031157 (country code 44)

Important Permissions

Make sure to allow:

• Microphone access for calls
• Notifications to receive incoming calls when the app is closed

On an iPhone, Focus mode can silence the app — turn Focus off or allow the app through in your Focus settings if calls aren't ringing. Permissions you declined can be changed later in your device's system settings.
