Enable or Disable ICE (Interactive Connectivity Establishment) for Linkus Mobile Client

ICE (Interactive Connectivity Establishment) is a technique used to establish direct connections between Yeastar PBX and Linkus, improving call quality by reducing network latency and packet loss. You can enable or disable ICE for users' Linkus Mobile Clients on PBX web portal based on their actual usage scenarios.


  • PBX Server: Version or later
  • Linkus Mobile Client:
    • Linkus Android Client: Version 5.3.12 or later
    • Linkus iOS Client: Version 5.3.6 or later


  1. Log in to PBX web portal, go to Extension and Trunk > Extension.
  2. Click beside the desired extension user.
  3. Click the Linkus Clients tab, then select an option from the drop-down list of ICE.
    Note: If you disable ICE, video calls will be unavailable on the user's Linkus Mobile Client.

  4. Click Save.


The ICE setting is synchronized to the extension user's Linkus Mobile Client, and will take effect when the extension user quits and reopens the APP or re-logins to the APP.

Note: Extension users can also change the ICE setting on their Linkus Mobile Clients (Path: Account > Settings > Audio Options > ICE), and the updated setting will be automatically synchronized to the PBX.
