TalkVoip works with any standard SIP provider or PBX system, including:

• FreePBX / Asterisk
• 3CX
• VoIP.ms
• Twilio
• Vonage
• Sipgate
• Any RFC 3261 compliant SIP server

Contact your provider for the specific server settings (host, port, transport).

To connect TalkVoip to FreePBX:

• In FreePBX, create an extension (PJSIP or Chan_SIP)
• Note the extension number and secret (password)
• In TalkVoip Settings, enter:
  • Username: Your extension number
  • Password: The extension secret
  • Domain: Your FreePBX server IP or domain
  • Port: 5060 (or 5061 for TLS)
• Tap Register to connect

Common causes of registration failure:

• Wrong credentials: Double-check your username and password
• Server address: Verify the host address is correct
• Port/Transport: Try different combinations (5060/UDP, 5061/TLS)
• Firewall: Ensure SIP traffic isn't blocked
• Account status: Confirm your account is active with your provider

BLF (Busy Lamp Field) keys allow quick call pickup and extension monitoring:

• Go to Settings and enable "Show BLF Keys"
• Configure your slot range (default: 71-78)
• BLF keys appear below the dial pad when enabled
• Tap a key to pick up a call on that slot

Currently, TalkVoip focuses on high-quality audio calls. Video calling is planned for a future release.
