It has been some time since any firmware was released for the UC320W whilst it may be EOL the support has not ended, are their plans to update the firmware?

Cisco dropped support for this unit shortly (14 months) after we bought it. Has many quirks that Cisco never addressed. Used to think Cisco products were very good; now I will never buy anything they make. Though EOL support doesn't end till 2016 though announcing EOL has lead to NO updates from support.
