Announcing UC320W 2.1.3(0) Limited Deployment Release


Today we are announcing the release of the  Cisco UC320W 2.1.3(0)  Limited Deployment Firmware release.  This release is available only via the Cloud by installing the attached Platform Modification File (PMF).   This is the 2.1.1(7) firmware with several key fixes/improvements added:

  • Critical compatibility issue with Adobe Flash Player version 11.  If you try to access a UC320W that is running a firmware version lower than 2.1.2 with Adobe Flash Player 11, you will only see a blue screen when trying to access the UC320W Configuration Utility.  This compatibility issue prevents the UC320W Configuration Utility from launching.
  • FXO based caller ID detection fix.
  • Inbound SIP trunk calls to voicemail fail to detect DTMF digits fix.
  • Call setup delay improvement.
  • Garbled Auto Attendant prompts when using G.729a CODEC fix.

Please see the 2.1.3 Release Notes for additional details.
