Yeastar Blog | S-Series New Firmware: Security Upgrade for Your PBX

We are very pleased to announce the new firmware version 30.10.0.28 for S-Series VoIP PBX. In this new version, we’ve made massive improvements to the system security and fixed some vulnerabilities that might be exploited by hackers, especially when your PBX is being used in a public network. This security update will better protect S-Series VoIP PBX against attacks and make your phone system more secure. We recommend you update the firmware as soon as possible.

Changes since firmware release 30.10.0.17.

  • Fixed the issue that Max Call Duration setting could not take effect.

Queue
