Corrections and Modifications

This release also includes the following corrections or modifications:


Now, the SIP stack is able to send its first message on the TCP/TLS connection. Previously, SIP stack sometimes failed to send the first message properly. (GVP-21626)


Media Control Platform now performs bargein correctly, when it receives a DTMF between issuing MediaPlay and the actual play. (GVP-21619)


Media Control Platform no longer terminates unexpectedly when the length of an MRCP packet is split across packets. (GVP-21615)


Media Control Platform no longer terminates unexpectedly when the length of an MRCP packet is split across packets. (GVP-21604)


Media Control Platform no longer stops reacting to OPTIONS calls from Resource Manager. Previously, a race condition could occur when MCP tried to send CPD results at the same time that the SIP transaction timer fired. This conflict could cause MCP to freeze and not respond to OPTIONS calls from Resource Manager. (GVP-21601)


An existing setting for the video_output_type option was modified to enable Media Server to identify the speaker in a conference, to the other attendees.

Option: video_output_type
Application: MCP
Section: conference
Valid values: single (this new setting is the default), mixed
Takes effect: Immediately

  • Set to single to specify single stream video output—the video stream from one conference participant is sent to every conference participant. This setting enables Media Server to identify the loudest participant in an audio-and-video conference as the speaker. Details:
    • All participants who are not the speaker, see the speaker in their conference video viewer.
    • The current speaker sees the previous speaker, or the conference's first participant if there is no previous speaker.
    • In a conference with only two participants, they always see each other, even if neither is speaking.
  • Set to mixed to specify mixed stream video output&emdash;the video streams from multiple conference participants are combined into one frame and sent to each participant, i.e., everyone sees everyone else.
(GVP-21574)

During a three-or-more-party conference, Media Control Platform no longer sends out audio packets between telephone-event packets of a DTMF. During a two-party conference recording, MCP no longer adds silence audio packets between telephone-event packets of a DTMF. Previously, the audio/telephone-event interleaved packets could cause problems with SBCs, leading to problems interacting with IVRs. (GVP-21571)


Media Control Platform now sends VAR and custom VAR data to the Reporting Server correctly. (GVP-21570)


64-bit Windows Media Control Platform deployments can now send Maintainer email notifications successfully. (GVP-21564)


Media Control Platform no longer terminates once every 49.7 days, due to a race condition related to Fetch Audio timers. (GVP-21525)
