+===== EPDDI =====
+[[epddi|EPDDI]] is available only at temporary events. EPVPN does not offer EPDDI.
+Offering EPDDI on EPVPN would require us to purchase a license we do not currently hold, build a multi-OMM setup, and operate and maintain a permanent SIP-DECT installation. We’ve decided against taking on the licensing costs and ongoing maintenance.
+===== FAQ and Troubleshooting =====
   * If your SIP client fails to register, check the server and the credentials for your **EPVPN** extension in GURU3.
