Disaster Recovery

Disaster Recovery is a crucial aspect of any modern communication system. It refers to the ability to smoothly continue telephony services in the event of a disaster or unforeseen event. With this new feature, Yeastar P-Series Software Edition users can create a PBX replica in a redundancy site and ensure uninterrupted telephony services in case of a primary site failure.

The geo-redundant setup boasts the following key advantages:

  • Real-time data mirroring to the redundancy site. No data loss or manual backup is required.
  • Automatic failure detection & fallback, ensuring minimal downtime during critical situations such as natural calamities, power outages, or network failures.
  • Inbuilt SD-WAN service for secure remote server networking or bring your own VPN service
  • Instant notification by call and email for any PBX server failure or automatic failover
  • Super simple setup
  • Can be combined with PBX Hot Standby (local redundancy setup) to build a higher level of system redundancy


  • This self-managed Disaster Recovery feature is currently only available for P-Series Software Editon.
  • This feature requires an additional PBX redundancy server to function.
