Fixed Issues

The following list contains fixes and improvements made to the Vocera Voice Server 5.7.x platform.

Fixed Issues in Version 5.7.0.89 (HF3)

The following list includes items fixed or improved in this version of the Vocera Voice Server.

  • CRVC-22061 In certain rare situations involving poor wifi connectivity, the VCG incorrectly sends a flood of silent RTP packets causing calling issues on VCS clients. This situation is now prevented by limiting the number of silent RTP packets used to correct lost RTP packets.
  • CRVC-22152 In certain situations, customers experience failover after a broadcast ends. This issue has been resolved.

Fixed Issues in Version 5.7.0.87 (HF2)

The following list includes items fixed or improved in this version of the Vocera Voice Server.

  • CRVC-21958 In certain situations, when a VCS client loses connectivity while in an instant conference, the session can fail to properly clear on receiving clients. This situation has been properly handled.
  • VCXP-15447 A mismatch in voice grammars caused Vocera Voice Server 5.7 to be incompatible with non-US locales resulting in failed recognitions. This incompatibility has been addressed.

Fixed Issues in Version 5.7.0.84 (HF1)

The following list includes items fixed or improved in this version of the Vocera Voice Server.

  • VCXP-15351/CASE-2602 Speech ports were not fully released after a pending allocation event. This resulted in a network traffic, which lead to a timeout in Nuance grammar load.

    This issue has been resolved by removing reference to unused patientname grammar as it was increasing grammar load time for each mainmenu request.

  • CRVC-22017/CASE-2711 Voice Server crashes on pressing the Call button when VMI alert is enunciated from multiple VMI clients sent with no response options.

    This issue has been addressed.

Fixed Issues in Version 5.7.0.82

The following list includes items fixed or improved in this version of the Vocera Voice Server.

  • VCXP-15059 Slow speech port leak makes Genie busy, and no speech ports are available until they failover.

    This issue has been resolved.

    CRVC-20796 A potential memory leak overwhelmed the system and impacted overall system performance.

    This issue has been addressed.

  • CRVC-20870 In some situations, the Voice Server may fail when a transferred call is accepted and then put on hold.

    The Voice Server no longer fails in this situation.

  • CRVC-20957 In rare situations, when a user calls a person whose calls are forwarded, the Voice Server may fail if the recipient of the forwarded call logs out just before the call is announced.

    This situation no longer occurs.

  • CRVC-21322 In some situations, the Bulk Assignment button in the Devices module of the Administration Console does not list available devices.

    The Bulk Assignment button now displays devices correctly.

  • CRVC-21458 You cannot set the Number of Days parameter on a VRS Report Scheduler package for the Device Last User Access report.

    The Number of Days parameter now works correctly.

  • CRVC-21474 In the Staff Assignment module, the columns do not align correctly with the header on the Assignments tab.

    The columns are now aligned correctly.

  • CRVC-21561 If you select a specific user in the parameters for the User Activity report in a VRS package, you cannot return the parameter to the default All Users setting.

    The VRS parameters now operate as expected.

  • CRVC-21118 A race condition involving VCS dialing an extension and immediately hanging up caused the VCG to stop sending keepalive signals to VMP. Once this occurs, the VCG will no longer properly process calls and will need to be restarted.

    This situation no longer occurs.

  • CRVC-21192 Certain rare scenarios involving bulk updates of the group forwarding information resulted in invalid configurations being saved.

    These scenarios no longer happen.
