Citrix Session Management


  • Users can login through web browser with Citrix receiver web client plugin or Citrix receiver desktop client. Reference -

  •  On login user pairs the BToE App by entering passcode generated by the VVX phone.


  • Based on installation option passcode (encoded IP address) shall be cached at BToE app client. On subsequent VDI sessions it will reconnect the phone automatically with cached passcode (encoded IP address).

    Note: Caching passcode option is recommended for persistence desktop sessions with dedicated VVX phone work space users.


  • On successful pairing the user will use the SFB client running on XenDesktop to do click to dial, answer incoming calls and join conference calls. On call establishment audio rendered on paired VVX phone.


  • BToE app shall unpair with VVX phone on:
    User explicitly logs off
    User disconnects the Citrix receiver window (controlled through config at time of BTOE installation, by default this is disabled)
    Citrix session times out (controlled through config at time of BTOE installation, by default disabled)
