IMPORTANT NOTICE for Mediant 9000 SBC and Mediant VE/SE/CE

From Version 7.2.202 (incl.), when using any transcoding/DSP functionality, the device must be configured to use the "Optimized-for-Transcoding" profile, by the SBCPerformanceProfile parameter. However, the parameter's value is not automatically set to this profile in all upgrade scenarios.

  • If you are upgrading from a version earlier than 7.2.158, for the parameter to be automatically set to this profile, first upgrade the device to Version 7.2.158 before upgrading it to Version 7.2.2xx.
  • If you are upgrading directly to Version 7.2.2xx from a version earlier than 7.2.158, then configure the device to this profile, using any of the below management methods. Once you have configured the parameter, you must save your configuration to flash with a device reset.
    1. ini file: SBCPerformanceProfile = 2
    2. CLI: configure system > sbc-performance-settings > sbc-performance-profile optimized-for-transcoding
    3. Web: 'SBC Performance Profile' = Optimized-for-Transcoding (SBC General Settings page - Setup menu > Signaling & Media tab > SBC folder > SBC General Settings)
