PIN-protected entry points in any call flow

The PIN Gate node prompts the caller for a numeric code and routes them down one of two paths based on whether they got it right. Configurable retry count and graceful "max attempts" handling.

What this lets you do

• Protect a direct-dial extension behind a PIN — common for after-hours emergency lines.
• Gate a conference bridge so only people with the code can enter.
• Lock a "transfer to voicemail without ringing" branch.
• Build a simple authentication step before a sensitive IVR option.

Setup

1. Drop a PIN Gate node into a flow.
2. Set the PIN.
3. Set max retry attempts (default 3).
4. Wire two outputs: Correct PIN and Failed PIN.
5. Save.

Worth knowing

Failed attempts go down the "Failed PIN" branch — typically you'd route them to an "access denied" message and hang up, or back to the main IVR for another try. The node uses Asterisk's native digit collection, so it interoperates correctly with overlap dialing and DTMF detection settings on every supported phone.
