title: How do I set initial value for ngx-intl-tel-input
body: <p>I am using ngx-intl-tel-input for phone number validation in my Angular project.</p>
  
  <pre><code>&lt;form #f="ngForm" [formGroup]="phoneForm"&gt;
  &lt;ngx-intl-tel-input 
  [cssClass]="'custom'" 
  [preferredCountries]="['us', 'gb']" 
  [enablePlaceholder]="true"
  [enableAutoCountrySelect]="true"
  [value]="'+91 8888888888'"
  name="phone" 
  formControlName="phone"&gt;&lt;/ngx-intl-tel-input&gt;
  </code></pre>
  
  <p></p>
  
  <p>I need to set value for the field which is coming from server.</p>
  
  <p>I have used <code>[value]</code> attribute, but it doesn't seem to be working.</p>
