Release notes

Added the following new features and changes

  • MSML <gain> Attributes tgtlvl and maxgain - adds support for the MSML<gain> attributes tgtlvl and maxgain for Automated Gain Control (AGC) settings in conferences that were previously configurable on a global level. MSML applications can use these attributes to provide low level control over the AGC gain levels on a conference by conference basis. The MSML <gain> tgtlvl attribute is used to set the desired target level for AGC, while the MSML <gain> maxgain attribute is used to set that the AGC may apply to the conference.
  • PowerMedia XMS codec profile is now supported through the RESTful Management API - Users can take advantage of the RESTful Management API to programmatically set the codec profile used to specify ordering of codecs for outbound calls or null SDP answers. Applications can now set unique codec profile during runtime for the PowerMedia XMS to use on a call-by-call basis.
  • PowerMedia XMS Release 4.0 Service Update 3 includes a behavior change for primitive termination cause in MSML. See release notes for detail.
