Customization

Learn how to customize WUCall's behavior.

Can I customize the SMS message?

Yes! You can customize the auto-reply message for each rule:

1. Go to Rules in the app
2. Tap on a rule to edit it
3. Modify the Message field
4. Save your changes

The default message is: "Thank you for calling, what is it about?"

You can personalize this to match your style or include your name.

How do I create custom rules?

1. Go to Rules in the app
2. Tap the + button to add a new rule
3. Configure the rule:
   • Name: A friendly name for the rule (e.g., "International calls")
   • Phone prefixes: Number patterns to match (e.g., "+44" for UK numbers)
   • Action: Whether to reject calls and send an SMS
   • Priority: Lower numbers = higher priority

What are phone prefixes?

Phone prefixes are the beginning of phone numbers used to match calls:

Prefix	Matches
+1	US and Canada
+44	United Kingdom
+336	French mobile
+337	French mobile
+331	French landline (Paris)
(empty)	All numbers (catch-all)

You can add multiple prefixes to a single rule.

How does rule priority work?

Rules are evaluated in priority order (lower number = higher priority):

1. When a call comes in, WUCall checks rules starting with the lowest priority number
2. The first matching rule is applied
3. If no rules match, the call rings normally

Example:

• Rule A (priority 10): Block +336, +337 (French mobile)
• Rule B (priority 20): Block all unknown

A French mobile number will match Rule A first.

Can I temporarily disable screening?

Yes! Simply tap the shield button on the home screen to toggle protection on/off. Your rules and settings are preserved.
