How to add multiple extensions?

Have a good day !!

How to add multiple extensions at once, like bulk extensions on FreePBX ?
Thank you guys.

This is possible when using Module Backup.

Just upload an XML file:

<sip>
   <phone>
      <extension>600</extension>
      <callerid>Stive</callerid>
      <secret>]?VpBfMh3!64</secret>  
   </phone>
   <phone>
      <extension>601</extension>
      <callerid>Ivan</callerid>
      <secret>]?VpBfMh3!64</secret>
   </phone>
</sip>
