Combined VoIP Validation

​
isZimVoip()

Validates if a number belongs to any Zimbabwe VoIP provider.

voipNumber
String
required
The VoIP number to validate
Returns: bool - true if valid Zimbabwe VoIP number from any provider, false otherwise Implementation: 
static bool isZimVoip(String voipNumber) =>
    isAfricom(voipNumber) ||
    isDandemutande(voipNumber) ||
    isLiquid(voipNumber) ||
    isPowertel(voipNumber) ||
    isTelco(voipNumber) ||
    isTelone(voipNumber) ||
    isZarnet(voipNumber);

​
Usage Example

// Accepts any Zimbabwe VoIP provider
if (LocalRegex.isZimVoip('0868812345')) {
  print('Valid Zimbabwe VoIP number');
}

LocalRegex.isZimVoip('0864412345');  // true (Africom)

Complete Example

import 'package:localregex/localregex.dart';

void validateVoipNumber(String number) {
  // Check specific provider
  if (LocalRegex.isLiquid(number)) {
    print('Liquid VoIP number');
  } else if (LocalRegex.isPowertel(number)) {
    print('Powertel VoIP number');
  } else if (LocalRegex.isTelone(number)) {
    print('TelOne VoIP number');
  } else if (LocalRegex.isAfricom(number)) {
    print('Africom VoIP number');
  } else if (LocalRegex.isDandemutande(number)) {
    print('Dandemutande VoIP number');
  } else if (LocalRegex.isTelco(number)) {
    print('Telco VoIP number');
  } else if (LocalRegex.isZarnet(number)) {
    print('Zarnet VoIP number');
  }
  
  // Or check if it's any Zimbabwe VoIP
  if (LocalRegex.isZimVoip(number)) {
    print('Valid Zimbabwe VoIP number');
  } else {
    print('Not a Zimbabwe VoIP number');
  }
}

// Example usage
void main() {
  final numbers = [
    '0864412345',  // Africom
    '0867712345',  // Liquid
    '0868812345',  // TelOne VoIP
    '0771234567',  // Mobile (not VoIP)
  ];
  
  for (final number in numbers) {
    validateVoipNumber(number);
  }
}

​
Best Practices

Use Specific Validators: When you know the expected VoIP provider, use the specific validation method (e.g., isLiquid()) for stricter validation.
Flexible Input: All VoIP validation methods accept numbers with or without country code prefixes (0, 263, +263).
VoIP vs Landline: TelOne has both landline numbers (validated by isZimLandline()) and VoIP numbers (validated by isTelone()). Make sure to use the correct validator based on the number type.
