No Audio on Tanberg EX90

                   We have about (4) Tanberg EX90 devices and over the last few months the audio is no longer working, no dial tone on touchscreen user interface.  We can hear users on a conference they can't hear us.  I am trying to determine if this is a hardware, software or a networking issue. 

Our network just migrated to VoIP on a Cisco platform.  Could it be a networking issue that is causing this?

We are at software version TC5.0.1. 275220 on the EX 90 and TT3.0.1.220275 on the touchscreen, is there a known issue with those versions that could be causing this?

Could this just be a hardware issue?

You could test two of the devices by setting them to direct dial and dial one's IP address from the other - this will bypass most things in the path that could be causing the issue and you'll be able to see if the devices work or if they're all faulty.

Are you EX90s registered to a VCS, or ar they now, with your network changes, registered to the Cisco call manager, and if so, have they been configured appropriately?

Another thing you may wish to look in to is upgrading the software from version TC5.0.1 - this is very old, and is subject to a number of vulnerabilities (See http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20130619-tpc).  The latest version is TC7.0.2.
