Release Notes:

The following new PowerMedia XMS features are available:

  • Cloud License Server Deployment - introduces cloud license server-based licensing deployment options through a revised product licensing mechanism. The new licensing mechanism provides a cloud-based network-wide licensing scheme to the PowerMedia XMS/MRB solution, in addition to a node-locked license mechanism.
  • Amazon Polly and Speech Profiles - adds support for Amazon Polly for Text-to-Speech (TTS) capabilities and speech profiles for dynamic selection of Text-to-Speech voices. Amazon Polly ( is an Amazon Web Service (AWS) that turns text into lifelike speech to build speech-enabled products using dozens of languages and voices.
  • SIP TLS Support - adds support for SIP Transport Layer Security (TLS), a security mechanism for SIP call control that operates on the transport layer. SIP TLS is the method used to secure the SIP signaling exchange using an authentication procedure between trusted SIP endpoints.
  • DTMF Digit Masking - supports the ability to mask DTMF digits that are recorded to the diagnostic log files. The ability to mask DTMF digits is important for security practices because DTMF digits can often carry personal information such as credit card info, social security numbers or private pin codes.
  • HTTP Client Authentication - provides HTTP client authentication by allowing users to enable HTTP client certificates. HTTP client certificates are used to identify the client and authenticates the client to the server for the server to verify the client’s identity and has permission to retrieve data.
  • Transient Recordings - introduces support for transient recordings, which are recordings that are associated with the call session and are deleted from the system when the session ends.
  • Configuration of RESTful API Username/Password - has been updated to support configuration of username and password for the RESTful Management API and RESTful Media API through the WebGUI.
  • Start/Stop Services Individually - adds support for individually starting and stopping system services. Users can now start and stop optional services without requiring a full system restart.
  • Provision for Dedicated SIP Control Channels - has been updated to support dedicated SIP control channels without the need to over-provision PowerMedia XMS ports. The dedicated control leg is a media-less SIP connection that then can be used to establish multiple conferences and send API commands.
  • Native Record H.264 to .mkv Files - has been updated with the capability to record native H.264 video to the Matroska (.mkv) file container.
  • Additional H.264 Video SDP Configuration - adds support for additional configuration of H.264 video SDP parameters.
  • NETANN Global Configuration Disable DTMF Clamping - a new global NETANN (Network Announcements) configuration parameter has been exposed to disable DTMF clamping in NETANN conferences.
  • Increased SDP Size Handling - has been updated to support larger SDP sizes, up to 12 KB. The increased SDP size handling is important for calls with large SDP payloads, especially WebRTC negotiations that advertise many candidates
  • Increased SIP INFO (MIME Buffer) Handling - has been updated to support larger SIP INFO MIME buffer sizes, up to 60 KB. Some MSML applications can require large SIP INFO payloads, especially to communicate many commands in a single script.

The following new PowerMedia MRB features are available:

  • MRB High Capacity - PowerMedia MRB has been enhanced to support up to 50 PowerMedia XMS instances to manage up to 100,000 total media sessions in a PowerMedia XMS media server cluster.
  • SIP Notification of Resource Moved - PowerMedia MRB has been enhanced to support up to 50 PowerMedia XMS instances to manage up to 100,000 total media sessions in a PowerMedia XMS media server cluster.
  • Failover of DTMF Listeners - PowerMedia MRB adds support for re-establishing DTMF listeners on call legs that are in a conference.
  • Preserve SIP Request URI - PowerMedia MRB adds a configuration option to preserve the SIP Request URI (User Request Indicator) through the PowerMedia MRB.
  • SIP (MSML) Control Channel Reuse - PowerMedia MRB has been updated to support applications that utilize a dedicated SIP control channel for control of multiple conference instances
  • TCP Upgrade for Large SIP Messages - PowerMedia MRB was upgraded with the ability to convert SIP messages from UDP to TCP when the packet size is greater than the maximum datagram MTU size.
