This article explains setting up SBC Edge to use the Music-on-Hold feature.

SBC SWe Lite supports playing MOH from Microsoft Teams during call hold scenarios.

Microsoft Teams uses different call flows for MOH :

  1. SIP REFER based MOH (MOHv1)
  2. SIP RE-INVITE based MOH (MOHv2)

SBC SWe Lite supports both these different call flows.
